Russo-Ukrainian War: PZL M28 Skytruck Gunship

Source: TF1Info.fr

     A dramatic screen capture from a video shot by a French TF1 media team for “Journal de 20 Heures” (“The 8pm News”) freezes the moment when an explosion of a Russian Geran-2 drone after being hit by the gunner bathes the aircraft in light. The story appeared on the news show on February 4, 2026 and follows a civilian crew flying a PZL M28 Skytruck equipped with a 7.62mm M134 minigun as they fly a mission to hunt down and destroy Russian drones.

     The PZL M28, built by PZL Mielec, is an improved variant of the original PZL An-28, a license built Antonov An-28 (NATO reporting name Cash) utility aircraft. PZL Mielec, today, is the only source for the An-28 and its derivatives. The PZL M28 first flew in the summer of 1993 and has remained in production ever since for both military and civilian customers. Crewed by two men, the PZL M28 can carry 17 paratroopers, 19 civilian passengers, or 5,071 pounds of cargo.

     Power comes from two Pratt & Whitney Canada PT6A-65B turboprop engines, each delivering 1,100 horsepower and each driving a Hartzell 5-bladed, reversible, constant-speed propeller. 602 gallons of fuel provide an operational range of 989 miles at an altitude of 9,800 feet with an endurance of 6.2 hours. Maximum speed is 221 miles per hour with a cruise speed of 152 miles per hour. Stall speed is 75 miles per hour. The PZL M28 can attain an altitude of 9,800 feet in 6 minutes with a maximum ceiling of 25,000 feet. Total length of the aircraft is 43 feet, a height of 16.1 feet, and a wingspan of 72.5 feet.

     The M134 minigun, originally developed by General Electric in 1960, entered U.S. military service in 1963 and it remains in production in various forms to this day. It is a 6-barrel, air-cooled, electrically driven rotary weapon which is chambered for the 7.62x51mm cartridge. The six barrels allow for an unprecedented rate of fire (depending on setting, between 2,000 to 6,000 rounds per minute) by having one barrel firing, two barrels in the cartridge extraction phase, with the remaining three barrels being loaded with a round. As only one barrel is firing in a rotation cycle, it permits cooling of the other barrels. The M134 requires an external power source to drive the barrels with the most common being electric though pneumatic or hydraulic power sources could also be used. Muzzle velocity is 2,800 feet per second with a maximum range of up to 2 miles. The M134 is fed using M13 disintegrating linked belts pushed into the weapon via a feed chute. A delinker strips off the link prior to the round being fed into the M134. Ammunition belts are from 500 to 5,000 rounds each. Typical ammunition boxes hold 1,500-, 3,000-, and 4,400 rounds. Standard sights are iron post but optics can be fitted.

     In the screen capture, the M134 is using an electric drive, the power cable visible just ahead of the rear spade grips. The ammunition feed chute is seen forward of the power cable. The L-shaped mount directly fitted to the M134 is standard U.S. military issue but the rest of the mount is custom built to accommodate the weapon within the PZL M28. The aircraft in the news story has 150 kills of which 115 are confirmed. During the filming of the story, the gunner scored five victories against drones. The destruction of the drone that resulted in the image was close enough to the PZL M28 that, upon landing, the ground crew found shrapnel holes in the plane's fuselage from the detonation.

The German Empire's "Flying Tank": The Junkers J.I

Source: Author's collection

     Military aviation in 1918 was, in many respects, a far cry from where it was in 1914. Aircraft were faster, more maneuverable, better armed, and more reliable. Aerial observation was a role aircraft fulfilled throughout World War I where the “eye in the sky” conducted reconnaissance on enemy positions and movements, served as spotters for artillery, and other tasks. Such missions were fraught with danger as the deployment of aircraft in roles which brought them close to the enemy meant the enemy developed the means to destroy them. By 1918, the advances of anti-aircraft weapons from ad-hoc solutions to dedicated anti-aircraft guns made the skies hazardous. In 1917, the Inspektion der Fliegertruppen (abbreviated to Idflieg; Inspectorate of Flying Troops) introduced the “J-class” of aircraft which were armored dual-role liaison/ground attack airplanes fitted with armor plate to reduce their vulnerability to ground fire. Typically, J-class planes were simply existing models with added armor. However, there was one such plane whose features would herald future ground attack aircraft: the Junkers J.I.

     In the photograph, a British soldier casts his gaze on the remains of a Junkers J.I (or it could be in the process of being scrapped postwar) and the wreckage amply displays the key features of the J.I. The J.I was of all-metal construction but as can be clearly seen, the J.I incorporated a fully armored “bathtub” which encompassed the 200hp Benz Bz.IV engine, pilot, and the observer. The armor, 5mm thick, also protected the fuel tanks and radio equipment. Other features which were designed to improve survivability included push-rod and bell cranks to operate the flight control surfaces instead of the usual steel cabling and a gravity feed fuel tank which enabled continued fuel flow to the engine in case the fuel pump failed. If the fuel in the gravity tank was exhausted, the J.I had a manual fuel pump the observer could use to move fuel from the main tanks into the engine. 

     For defensive armament, the observer had a rear firing, flexible mounted 7.92mm MG14 machine-gun with five ammunition drums of 200 rounds each. The J.I could also be fitted with two downward firing machine-guns when deployed as a ground attack craft though this was rarely done. 

     The first J.I aircraft were taken into service in August of 1917 with the first combat deployment occurring during Germany’s Spring Offensive (Kaiserschlacht; Kaiser’s Battle) which commenced in March 1918. Crews of the J.I nicknamed it the “Möbelwagen” (“Furniture Van”) due to the sluggish handling but they appreciated the protection. Source depending, either no J.I aircraft were lost to enemy fire or only a single J.I was brought down, the French claiming one from an anti-aircraft machine-gun firing armor piercing ammunition. In all, 227 J.I aircraft were built.

Messerschmitt Me 163B V13: Abandoned in Pölzen

Source: U.S. Army Signal Corps

     Found by troops of Combat Command A, 9th. Armored Division, 1st. U.S. Army in April 1945 was the remains of Messerschmitt Me 163B V13, Werk Nummer (W.Nr.) 10022, fuselage code VD+EV. The location was a airfield hangar in Pölzen, Germany located to the northeast of Leipzig. While the men of Combat Command A likely did not know it at the time they came across the ruins of the aircraft, the V13 had been the start of the further development of the Me 163 rocket fighter that ultimately culminated in the Messerschmitt Me 263 (also designated as the Junkers Ju 248).

     One of the most serious problems with the Me 163B rocket interceptor was the ravenous consumption the Walther HWK 509 A-2 bi-fuel rocket motor had for the reactant propellants, T-Stoff and C-Stoff. Once the Me 163B achieved operating altitude, the aircraft had only 2.5 minutes worth of powered flight left before the tanks ran dry. Typically, given the volatile and explosive nature of the fuels, pilots would often exhaust the entire fuel supply rather than risk having fuel onboard while in combat, let alone coming to a landing which risked causing a detonation if the touchdown was rough. In combat operations, it meant that the range of the Me 163B was severely restricted and unless airfields operating the rocket fighter were near known bomber routes, the Me 163B was more or less impotent. In fact, when U.S. Intelligence determined an airfield was housing a Me 163 unit, they advised U.S. Army Air Force bomber units to simply plot bombing strike avenues to avoid the airfield. Another problem with the Me 163B was that is had no landing gear outside of a central skid. It took off atop a two-wheeled dolly which was then jettisoned once the plane was airborne. Upon landing, it had to be recovered by a special trailer pulled by a three-wheeled tractor called a Scheuschlepper. The V13 was the first step in overcoming the first of these two main concerns with the fighter.

     The V13 was the first to trial a new Walther rocket engine, the HWK 509 C. While the fuels were the same, the biggest difference was the addition of a cruise chamber. The HWK 509 C's main chamber produced 3,750 pounds of thrust but the cruise chamber only provided 660 pounds of thrust. The idea was that for take-off, both chambers would be engaged for a total of 4,410 pounds of thrust. Once the aircraft was at operational altitude, the main chamber would be shut off and the aircraft would fly only on the cruise chamber. As such, the new engine provided up to 6.5 minutes of powered flight before the fuel ran out. The V13 was much the same as the standard Me 163B except that the tail was modified to accommodate the cruise chamber which was to be used in the new development of the aircraft which was then called the Me 163D. The first flight of the V13 took place in December 1943 and the last known flight occurred on May 14, 1944. Two other Me 163B aircraft were part of the Me 163D project and these were the V10 (W.Nr. 10019, fuselage code VD+ES) and the V18 (W.Nr. 10027, fuselage code VA+SP). The V10, having originally been used to test a BMW rocket motor and a revised fuel tank system, was repurposed to trial the tricycle landing gear that was to be used on the Me 163D. The V18 was also refitted with a HWK 509 C engine and on July 6, 1944, pilot Rudolf Opitz took the aircraft up for a calibration flight and the engine was at maximum thrust and as it accelerated, the critical Mach number was exceeded. Opitz cut fuel to the engine which put the V18 into a steep dive Optiz was only able to recover feet from the waters of the Baltic Sea. After landing, the entire rudder was missing and readings taken during the flight showed the V18 had attained a speed of 702mph.

     The results of testing with the V10, V13, and V18 culminated in the Ju 248 which was a nearly complete redesign of the Me 163 fighter. The designation Junkers Ju 248 came into play as work on the project was shifted to Junkers in the spring of 1944 in light of the Messerschmitt company's other development work and production obligations. The name would revert to Me 263 by August of 1944. The new aircraft utilized a new fuselage that incorporated a bubble canopy, retractable landing gear, and a HWK 509 C-4 bi-fuel engine which it was estimated would give the Ju 248 a maximum powered endurance of between 9 to 15 minutes altitude depending. While better than the maximum 7.5 minutes of total powered endurance with the Me 163B, it was not a significant increase overall though the ability to be more mobile on the ground lowered the time it took to for ground crews to turn the aircraft around for another sortie. 

     As it was, the Ju 248 V1 was completed and performed well in unpowered, towed testing but it was never flown under power and ended up captured by the Soviets who shipped it back to Russia for study. The Mikoyan-Gurevich I-270 rocket interceptor, first flown in 1946, drew heavily from the Me 263 but the entire concept of a rocket powered, point interceptor was flawed and the I-270 was abandoned.

Avia B.534: Pre-War Fighter Excellence

Source: Author's collection

     The Avia B.534 is considered by some to be the most important Czechoslovakian aircraft built during the 1930s and was certainly the most well known to many nations of the time. It was also the most prolific in terms of production numbers with 566 of all B.534 types being constructed. The man behind the B.534 was František Novotný and throughout 1932, he designed the B.34/2 with the first prototype taking to the air on May 25, 1933. The aircraft, now designated the B.534-I, was turned over for testing and on September 10, 1933, the public got to see the new fighter at an exhibition. The second prototype was completed in late September 1933 and featured a fully enclosed cockpit. Extensive testing was carried out through the first half of 1934 with April 14, 1934 standing out when test pilot Václav Kočí flew the second prototype to a Czech national speed record of 227.2mph. The Czech Air Force (Vzdušné Síly) finally put in an order for the B.534 on July 14, 1934 with an initial purchase of 34 aircraft with first deliveries occurring in October 1935. The most numerous version in service was the B.534-IV, with 253 being built, and that is the aircraft shown here.

     The B.534-IV was powered by a Hispano-Suiza HS 12Ydrs 12-cylinder, liquid-cooled V engine developing 850 horsepower which gave the aircraft a top speed of 245mph at 14,435 feet and a climb rate of 2,953 feet per minute. The B.534-IV had a wingspan of 30.1 feet, a length of 26.1 feet, height of 10.2 feet, and a wing area of 253.61 square feet. Armament consisted of four 7.92x57mm Kulomet vz. 30 machine-guns fitted in the forward fuselage with 250 to 300 rounds of ammunition per gun. If need be, six 22 pound bombs or four 44 pound bombs can be carried on underwing racks. The loaded weight of the B.534-IV was 4,674 pounds and with full tanks, the fighter had a range of 360 miles. At the time the B.354-IV entered service, it was superior to many of the fighters fielded by the British, U.S., and the Soviet Union. In fact, even in 1937, the B.534 stood up well against many fighters, only being truly bested by the Messerschmitt Bf 109B.

     The aircraft in the photograph belonged to the Slovak Air Force (Slovenské Vzdušné Zbrane) which came into existence when the Slovak State (Slovenský Štát) began on March 14, 1939 following its declaration of independence from Czechoslovakia. A client state of Germany, Slovak forces participated in the German invasion of Poland, the only other Axis country to do so. Slovak units under Field Army Bernolák (Slovenská Poľná Armádna Skupina "Bernolák") fought in Poland from September 1 through September 16, 1939, subordinated to the German 14. Armee under Heeresgruppe Süd (Army Group South). The Slovaks were victorious in seizing territory in a disputed region along the Poland-Slovakia border. Later, in 1941, the Slovak Expeditionary Army Group and later the Pilfousek Brigade fought in Russia, being attached to the German 17. Armee. However, the Slovak forces lacked command structure, had logistical problems, and were short on motorized transports and despite seeing some frontline combat, were usually relegated to rear-area security operations. Involved in the Russian campaign were three Slovak Air Force squadrons. The B.534-IV aircraft used by the Slovak Air Force had been former Czech Air Force planes but by mid-1942, the fighter was long eclipsed by superior designs and was removed from front-line service and distributed to training units.

     The B.534-IV seen here has a German Balkenkreuz painted on the fuselage, no doubt to aid in identification and prevent friendly fire incidents. The emblem on the tail rudder was that of the Slovak Air Force and consisted of a double cross on a field within a circle. In this case, the cross is blue on a red field within a white circle. Some aircraft had a red cross on a blue field. This emblem was repeated on the top of the wings and on the bottom of the lower wings. In addition, some B.534-IV aircraft added the German Balkenkreuz beside the Slovak emblems. Later, Slovak Air Force aircraft used their own version of the Balkenkreuz that consisted of a blue cross with white borders with a red circle in the center. The overall color was a dark green with whitish-gray undersides.

     The Slovak Air Force ceased to be when the Slovak State came to an end on April 4, 1945 when Slovakia fell to the Russians during the Bratislava–Brno Offensive and both Slovakia and Moravia were returned to Czechoslovakia. Other users of the B.534-IV during the war was Bulgaria which operated some 48 to 78 aircraft (which they called the “Dogan“, or Hunting Hawk), Germany (mostly as training aircraft and glider tugs), and Romania (which used several as glider tugs). 

     Today, no complete B.534 exists in the world. A replica B.534-IV is on display at the Prague Aviation Museum in Kbely, Czechoslovakia while another replica, a cannon-armed Bk.534 variant, is on display at the Slovak Technical Museum at Košice International Airport, Slovakia. Both replicas incorporate some original parts but the majority of the components had to be fabricated. There is also a airworthy replica, though not to scale (it is 30% smaller than the actual B.534) that was built by Stanislav Fiala starting in 2002. The first flight took place in 2009 but following testing, needed modifications which made Ultralight certification difficult. It was not until October 2012 was the replica certified and it carries the code OK-QAB-1. Power comes from a Walter Mikron III engine with the frame being chrome-molybdenum tubing with wooden wings and tail surfaces. The plane is painted in the colors of the 1. Letecky Pluk (1st. Air Regiment), either the 32. Letka or 34. Letka (32nd. or 34th. Squadron), of the Czech Air Force.

Russo-Ukrainian War: The Sukhoi Su-24MR Fencer-E

Source: ArmyInform

     Photographed in late May 2024, the Sukhoi Su-24MR (NATO reporting name Fencer-E) “Yellow 11” rests in its revetment. The aircraft belongs to the 7th. Tactical Aviation Brigade “Petro Franko”. The Su-24MR is the dedicated reconnaissance variant of the Su-24M tactical bomber and first entered service in 1983 with production ending in 1993 after 130 examples were built.

     Externally, the Su-24MR looks much like the Su-24M upon which it is based. But, there are some visible differences which tell them apart. The first can be seen underneath the fuselage, along the centerline, a bit forward of the side intakes. In place of the Gryazev-Shipunov GSh-6-23M rotary 23mm cannon, a fairing contains a AP-402M panoramic 90.5 focal length camera and behind it, a “Aist-M” (“Stork-M”) TV camera/reconnaissance system. Of interest, the cassette cartridge that stores the photographs taken by the AP-402M can be jettisoned, the cartridge falling to earth via parachute.

     Another external means to tell the Su-24MR apart from the Su-24M assumes it is fitted with a SRS-14 “Tangazh” (“Pitch”) ELINT (Electronic Intelligence) pod, as fitted here underneath the fuselage. The SRS-14 is designed to detect emitting radars then determine their origin point, the type of radar(s), and the mode the radars are operating in. Another specialized pod which is used is the Shpil'-2M (“Spire”) laser imager with a 25cm resolution. Altitude affects the image quality so that when flying at low altitudes, the quality improves to almost photographic levels. The “Spire” can be used day or night and the image data can be transmitted to ground stations in real time.

     On the outer pylon of the right wing looks to be a M-341 Efir-1M (“Ether-1M”) radiation detector. It measures radioactivity levels and records the data onto magnetic tape or, if desired, the pod can transmit the data to ground stations. The drop tanks are PTB-3000 models which hold 793 gallons of fuel each.

     The nose-mounted Orion-A radar suite used by the Su-24M is replaced with a RDS-BO “Shtyk” (“Bayonet”) SLAR (Side-Looking Airborne Radar). The minimum range of the radar is .2 of a mile to a maximum range of 17 miles. The RDS-BO (sometimes designated the M-101) is a pulse-only radar, is able to classify ground targets, and is equipped with a moving target indicator. This data is compiled via the BCR-1 intelligence complex (which also assesses information taken in from other sensors).

     Because the Su-24MR is unarmed, it is fitted with extensive defensive systems, collectively called the BKO-2M Karpaty complex. It consists of the SPO-15M Bereza (“Birch”) which alerts the crew to being “painted” by radar and also homing radar as used by missiles. Against infrared homing missiles, the L-082 Mak-UL (“Poppy”) detector is fitted for alerting to missiles that utilize infrared seeker heads. Another piece of the complex is the SPS-161/162 Geran-F (“Geranium-F”) radar jammer along with the APP-50A flare dispenser. The entire complex was controlled by a Neon-F digital computer system.

     Other reconnaissance equipment include the A-100 oblique mounted camera which has a 1,000 focal length. The aperture for the camera is mounted underneath the left air intake. Finally, there is a “Zima” (“Winter”) infrared sensor system mounted beneath the right air intake and it can just be seen near the rake fitted to the edge of the intake.

     “Yellow 11” first saw combat during the Donbas War when, on July 2, 2014, a separatist fired MANPADS (Man Portable Air Defense System) struck the aircraft while it was operating over Slavyansk, Donetsk Oblast. The strike caused a fire which forced the crew to shut down one of the engines. The stricken Su-24MR was able to return to base but upon landing, a new fire started which caused significant damage before it was extinguished by ground crew. It would take many months to repair the aircraft but in April 2015, “Yellow 11” was back in service.

Russo-Ukrainian War: The Sukhoi Su-24M Fencer-D w/ Vympel Kh-29L

Source: Reddit

     A Sukhoi Su-24M (NATO reporting name Fencer-D) belonging to the 7th. Tactical Aviation Brigade “Petro Franko” sorties for a mission. This particular photograph started appearing in social media in early November 2024 though given the color of the foliage, it was taken much earlier (possibly in August 2024).

     Based on the minimal armament and lack of external fuel tanks, the mission may be a training one or a combat mission within the standard range of the Su-24M. Speaking of armament, the visible weapon is a Vympel Kh-29L (NATO reporting name AS-14 Kedge-A) air-to-surface missile. By no means is the Kh-29 missile new, having first appeared in service in 1980 with development having begun in 1975. Primarily, the Kh-29 family of missiles is used against targets such as buildings, bridges, airfields, hardened shelters, and even against large naval vessels.

     The Kh-29L is powered by a solid fuel rocket motor that pushes the missile through the air at a maximum speed of 1,400 miles per hour. The operational range is 6 miles. The missile is brought onto target by semi-active laser homing. This is accomplished using the integral Kaira-24 laser designator fitted into the Su-24M. The laser has a maximum range of 11.5 miles and so while the Kh-29L could travel further, its range is limited to that of the designator. The Kaira-24 is more of a targeting system that consists of the laser designator (called Spire) which is tied into the ILS-31 HUD (Heads-Up Display) used by the WSO (Weapon Systems Officer). The Kh-29L arms within 1.2 miles and has a flight envelope as high as 3 miles in altitude down to as low as 200 meters off the ground.

     Curiously, the Kh-29L is missing the vanes on the seeker head and the four rotating ailerons on the forward portion of the missile.

     Of interest is the yellow underside of the Su-24M. At the start of the Russo-Ukrainian War, both sides used Soviet-era aircraft, to include the Su-24M and Su-24MR (of which Russia still has some 300 in service). As such, in April 2022, the 7th. Tactical Aviation Brigade painted the undersides of their Su-24 aircraft yellow to enable Ukrainian ground forces to easily identify them and avoid any further friendly fire incidents. The dragon is a rendition of the brigade's crest that consists of a heraldic black dragon. Finally, the insignia beneath the cockpit is actually the “winged archer” logo used by the Sukhoi Design Bureau (which is part of the Sukhoi Aviation Military Industrial Combine or Sukhoi AMIC) which designed and built the Su-24.

Russo-Ukrainian War: The Sukhoi Su-24M Fencer-D

Source: ukraine_defense on Instagram

     The only tactical bomber the Ukrainian Air Force currently fields in the Russo-Ukrainian War is shown here: the Sukhoi Su-24M. Often called by its NATO reporting name, Fencer-D, the Su-24 entered service with the Soviet Union in 1974 and although production of the Su-24 ceased in 1993, it remains in front-line service with six nations of which Ukraine and Russia are included in that number. This particular Su-24M belongs to the 7th. Tactical Aviation Brigade “Petro Franko” which is the only unit within the Ukrainian Air Force that operates the Su-24. The brigade has suffered heavy losses, most occurring in the opening months of the Russo-Ukrainian War which started in February 24, 2022 with the Russian invasion. In 2022, the unit lost a total of 24 aircraft with sixteen crew killed in action and three missing in action. To date, the last confirmed loss of a Su-24 occurred on March 1, 2023 with the loss of both crew members. A report by the International Institute for Strategic Studies in February 2024 gave the inventory of surviving aircraft at thirteen with five being the Su-24M and the remainder being the reconnaissance variant, the Su-24MR (Fencer-E).

     The Su-24M started to appear in Soviet units in 1983. Power comes from two Lyulka AL-21F-3A turbojets with each engine capable of 17,000 pounds of thrust. With the afterburner engaged, this increases to 24,700 pounds of thrust each. Clean and without afterburners, the Su-24M can achieve a maximum speed of 1,028 miles per hour near the plane's service ceiling of 36,000 feet. At sea level, the top speed is 817 miles per hour. At full thrust, the Su-24M has a climb of 30,000 feet per minute. For range, the average is 382 miles with a 6,614 pound load of ordnance and external fuel tanks. The Su-24M has 24,471 pounds of onboard fuel and without ordnance but with external fuel tanks, the ferry range is 1,724 miles. The Su-24M has a two man crew, the pilot and the WSO (“Whizzo” or Weapon Systems Officer), and they sit side-by-side in the cockpit. Each is provided with a Zvezda K-36D ejection seat.

     The Su-24 has variable swept wings which have four sweep settings. For take-off and landing, the wings are swept at 16 degrees while for cruising, the sweep is either 35 degrees or 45 degrees altitude depending. The final sweep setting is 69 degrees to reduce the aspect ratio and provide for maximum speed. The variable wings also allow for a low landing speed for such a large aircraft at 140 miles per hour. The original model, the Su-24 (Fencer-A), was capable of 1,440 miles per hour at 57,400 feet but since the usual mission profile was low altitude, the complex (and heavy) variable intake ramps were removed in later models such as the Su-24M to lower weight and simplify maintenance. It did, however, drop the maximum speed to what is outlined above.

     The only on-board armament is a single Gryazev-Shipunov GSh-6-23M rotary 23mm cannon which is provided with 500 rounds of ammunition. There are eight hardpoints with four on the underside of the fuselage and two per wing. The outer wing hardpoints can swivel to remain in place as the wings change sweep angles. A total of 17,635 pounds of stores can be carried by the Su-24M, to include the full array of Soviet-era missiles, rockets, and bombs. This was one of the factors that caused the high rate of attrition of the Su-24M in 2022 as the aircraft had no munitions that could be fired at Russian targets outside of Russian anti-air defense ranges. When the Ukrainian Air Force began to receive Western aerial weapons capable of stand-off ranges (meaning, the weapon can be deployed against Russian targets without the aircraft being within anti-aircraft gun or missile ranges), the Su-24M became the primary delivery system. By consequence, there have been no confirmed Su-24M losses since March 2023.

     The Su-24M shown here is equipped with two Storm Shadow cruise missiles which have been provided to Ukraine by Great Britain. France has also provided Ukraine with the Storm Shadow though in French use, it is called the SCALP-EG (Système de Croisière Autonome à Longue Portée – Emploi Général meaning Long Range Autonomous Cruise Missile System – General Purpose). The Storm Shadow was designed by Matra BAe Dynamics and is built by MBDA with the first missiles becoming operational in 2003. At a cost of 2.5 million U.S. dollars each, the Storm Shadow is powered by a Microturbo TRI 60-30 turbojet which generates 1,200 pounds of thrust. This gives the missile a 729 miles per hour. Maximum range is 342 miles. Guidance is a combination of GPS, an inertial navigation system, infrared thermography, and TERPROM (Terrain Profile Matching). Steering is accomplished by four vertical and two horizontal tailplanes. Target data is programmed into the Storm Shadow prior to mission launch and once the missile is released, the mission profile cannot be changed nor terminated. The 990 pound warhead uses a multi-stage BROACH penetrator (Bomb Royal Ordnance Augmented Charge). It consists of a shaped charge which strikes first, punching through exterior concrete, earth, or armor, which then permits the follow-on charge to detonate inside the target. The usage of TERPROM provides the Storm Shadow with resistance to Russian GPS signal jamming. Ukrainian Su-24M launch the Storm Shadow from the inboard wing hardpoints using a pylon adapter taken from former Royal Air Force Panavia Tornado GR4 multi-role aircraft. Underneath the fuselage is a PTB-3000 external fuel tank that holds 793 gallons of fuel. The downward pointing fins on the front of the tank ensure the tank falls away from the aircraft if it has to be detached in flight. Other stand-off munitions currently known to be used by Ukrainian Su-24M aircraft are domestically made gliding bombs, the venerable Kh-25ML tactical air-to-surface missile (NATO reporting name AS-10 Karen), U.S. supplied JDAM-ER (Joint Direct Attack Munition-Extended Range) guided bombs, and French supplied AASM HAMMER guided bombs.

     Other equipment on the Su-24M include the Puma navigation/attack suite (consisting of two Orion-A radars which permit day/night capability), Relyef terrain clearance radar (allows for automatic piloting at low altitudes), Orbita-10-58 computer, Shchel helmet-mounted sights for the crew, multi-function displays, digital moving-map generator, Sirena radar-warning receiver, active ECM (Electronic Countermeasure) suites (which can be seen as the triangular protrusions at the top of the vertical stabilizer and on the intake sides), capability to carry chaff and flare dispensers, inflight refueling capability, PNS-24M inertial navigation system, Tekon track/search system for guided munition use, and a Kaira-24 laser designator with TV-optical display.

Russo-Ukrainian War: The Sukhoi Su-25M1 Grach

Source: UKR_Air_Patrol on Instagram

     Another Soviet-era aircraft seeing heavy use in the Russo-Ukrainian War is shown here, the Sukhoi Su-25 Grach (“Rook”; NATO reporting name Frogfoot). Currently, all of the Su-25 aircraft in the Ukrainian Air Force are operated by the 299th. Tactical Aviation Brigade “Vasyl Nikiforov”. The particular aircraft in the photograph (which is not recent) is “Blue 08”, a Su-25M1, that was flown by Captain Vladyslav Voloshyn until the aircraft was shot down on August 29, 2014 by a MANPADS (Man Portable Air Defense System) or a SAM (Surface-to-Air Missile) system during the Battle of Ilovaisk which ran from August 7 to September 2, 2014. Voloshyn successfully ejected and it took him four days to make his way back to Ukrainian lines. The Su-25M1, and variants of it, remain the mainstay of the brigade's attack aircraft. The Su-25 is a dedicated ground attack/close air support aircraft, analogous to the U.S. Air Force's Fairchild Republic A-10 Thunderbolt II. Production started in 1978 with the first Soviet Air Force units fielding the Su-25 beginning in 1981. The last Su-25 rolled off the manufacturing line in 2017.

     The Su-25M1 (which is a Ukrainian modernization of the standard Su-25) is powered by two Tumansky (Gavrilov) R95Sh axial-flow, non-afterburning turbojets with each engine providing a maximum of 9,037 pounds of thrust. This is enough to provide the Su-25M1 with a maximum speed of 590 miles per hour at sea level. Maximum range is around 620 miles though with 9,700 pounds of war load and two external fuel tanks, a combat range of 470 miles can be achieved. The engines provide for a rate of climb of 11,400 feet per minute and the Su-25M1 has a service ceiling of 23,000 feet.

     Befitting a ground attack/support aircraft, the Su-25 has a number of features to enable it to survive and operate. In the nose is a Kylon-PS laser rangefinder/target designator, a DISS-7 Doppler speed/drift sensor beneath the cockpit (paired to the KN-23-1 [see below]), SSP-2I fire warning system with two UBSh-4-2 fire extinguishers, ASO-2V chaff/flare dispensers, SPO-15 Beryoza (“Birch”) radar homing warning system, AKS-5 gun camera, SO-69 transponder, SRZO-2 Khrom-Nikel IFF (Identification, Friend or Foe) interrogator with a SRO-2M Khrom IFF transponder, KN-23-1 navigation suite (which includes the RSBN-6S short-range radio navigation system, ARK-15M automatic direction finder, RV-15 radio altimeter, UUAP-72 angle-of-attack indicator/accelerometer, SVS-1-72-18 air data computer, PVD-18G-3M and PVD-7 pressure probes, and a MRP-56P marker beacon receiver), R-862 transceiver, R-828 VHF transmitter-receiver, and a ASP-17BTs-8 computing gun sight.

     The pilot sits within a tub made of ABVT-20 titanium alloy armor plates which range between 10mm to 24mm thick. The pilot is provided with a K-36L ejection seat and just behind the headrest is a 6mm thick plate of steel armor secured to the bulkhead. The canopy windshield is made of 65mm thick TSK-137 triplex bulletproof glass. To see behind him, the pilot has a rear facing periscope (atop the canopy) and two rear-view mirrors in the canopy frame. Because the Su-25 is not meant for high altitude flight, the cockpit is not pressurized. The cockpit is, however, NBC (Nuclear Biological Chemical) protected by an overpressure system and dust filters. The pilot wears a KP-52M oxygen mask, the aircraft's oxygen system providing a oxygen mix at altitudes of 1.2 to 4.3 miles and over that, up to the Su-25's ceiling, the pilot breathes pure oxygen. In case of ejection, the seat includes a BKO-3VZ emergency oxygen system.

     Other protective systems in the Su-25M1 include 20mm thick protective material around the fuel tanks while the fuel tanks themselves are fitted with explosion-suppression polyurethane foam. The Su-25M1 has two independent hydraulic systems that operate flight controls, braking, and the landing gear and this provides for redundancy in case of damage. The engines are capable of surviving, and will continue to operate, after taking a direct hit from a 23mm cannon shell. Despite this, armor plating is fitted on the underside of the aircraft, forward of the engine cowlings, as well as around the engine exhaust zone and rear parts of the engine nacelles. Armor is also added to the rear fuselage sides as well as armor fitted to the underside of the main service fuel tank within the fuselage. Flight controls, namely the elevator control rods, are duplicated to enhance survivability. In the tailcone are two PTK-25 cruciform brake parachutes.

     The main weapon of the Su-25M1 is the VPU-17A cannon installation that consists of a single Gryazev-Shipunov GSh-2-30 twin-barrel 30mm cannon which is provided with 250 rounds of belted ammunition. The cannon has a maximum rate of fire of 3,000 rounds per minute with a range of 1.1 miles. There are eleven hardpoints (four on each wing and three centerline) on the Su-25M1 which enables the aircraft to carry up to 8,800 pounds of stores. Common weapons carried include the S-5 55mm unguided rocket, the larger S-8 80mm unguided rocket, FAB-250 (550lb.) and FAB-500 (1,100lb.) free-fall bombs, and more recently, French-made AASM HAMMER guided bombs. If available, the Su-25M1 can utilize the SPPU-22 cannon pod which is equipped with a Gryazev-Shipunov GSh-23 twin-barrel 23mm cannon and 260 rounds. Auxiliary fuel capacity can come from either the PTB-800 (176 gallons) or PTB-1150 (253 gallon) drop tanks. Up to four tanks can be carried.

     Specifically, the Ukrainian modernization program was carried out by MiGremont and included adding a new GPS receiver, upgrading the radio communication systems, enhancing the gun sight, and adding a digital flight data recorder. The modernization has allowed the Su-25M1 to fire the S-13 122mm unguided rockets.

     The 299th. Tactical Aviation Brigade started the Russo-Ukrainian War with twenty-four Su-25 of various models (to include two-seat trainers) operational. Since April 2023, mothballed Su-25s have been withdrawn from storage and refitted to replace losses. Another two Su-25 were obtained from Macedonia. Speaking of losses, there have been 10 confirmed Su-25 losses (based on their fuselage numbers) with nine pilots killed and one captured by Russian Federation forces. Another ten aircraft have also been reported lost (though what their fuselage numbers are isn't known) in combat and on the ground with the loss of four pilots as confirmed killed with another two pilots probable KIA. One pilot, Roman Vasyliuk, was shot down on March 14, 2022 and captured but later released on April 24, 2022 in a POW swap.

     As for Russian losses, to date, the Russian Air Force has lost thirty-eight Su-25 aircraft as confirmed by the Oryx website.

Russo-Ukrainian War: The Mikoyan MiG-29 Fulcrum

Source: Reddit

     A Mikoyan MiG-29 (NATO reporting name Fulcrum) of the 40th. Tactical Aviation Brigade “Ghost of Kyiv” sporting an impressive tally of bombing missions, 69 in all. The MiG-29 is the most numerous fighter in the Ukrainian Air Force and the majority of them are operated by the 40th. The most numerous version in Ukrainian service is the MiG-29 (Product 9.13) Fulcrum C which appeared in 1989.

     The MiG-29 is powered by two Klimov RD-33 turbofan engines fitted with afterburners and each engine is capable of 11,110 pounds of thrust without afterburner and 18,340 pounds of thrust at full afterburner. This provides for a maximum speed of 1,520 miles per hour (just at Mach 2). The airframe is rated for +9 g forces. With 998 gallons of onboard fuel (excluding drop tanks), the MiG-29 has a maximum combat range of 560 miles when loaded out with six AAMs (Air-to-Air Missiles). With just internal fuel and no munitions, the range is 890 miles. Ferry range, with three drop tanks, is 1,802 miles. Rate of climb is 1,082 feet per second which means the MiG-29 can attain it's 60,000 foot service ceiling in a little under a minute.

     The only onboard armament is a single Gryazev-Shipunov GSh-30-1 30mm autocannon which is provided with 150 rounds. A short recoil operated weapon, the GSh-30-1 has a maximum rate of fire of 1,800 rounds per minute with an effective range of 1.1 miles. The autocannon can fire ammunition to allow the pilot to engage ground targets but in the Russo-Ukrainian War, such an attack is too great a risk with the prevalence of MANPADS (Man Portable Air Defense Systems) and other anti-air weapons. As such, it is likely Ukrainian MiG-29s carry ammunition suitable for air combat and such rounds have distance-armed, delayed action fuzes.

     The MiG-29 has seven hardpoints, one underneath the fuselage and three per wing. All together, the MiG-29 can carry 8,818 pounds of war load. Common AAMs used by Ukraine include the Vympel R-73 (NATO reporting name AA-11 Archer) and the older Vympel R-27 (NATO reporting name AA-10 Alamo). Interestingly, because of the lack of air-to-air combat between Ukrainian and Russian fighter jets, many R-73 missiles are being repurposed as SAMs (Surface-to-Air Missiles) for use by air defense ground forces. Befitting the bomber role, the MiG-29 can carry four of the common Soviet-era FAB-250 550 pound bomb or the larger FAB-500 1,100 pound bomb. Likewise, Russia is making heavy use of both types of bombs against Ukrainian targets. In some instances, the Russians have created wing packages that allow the bombs to glide, extending their range. However, the Ukrainians are using primarily non-Soviet munitions but offering similar glide capacity. The first is the JDAM-ER fitted to GBU-62 bombs. The Joint Direct Attack Munition-Extended Range is a kit that turns a regular free-fall 1,000 pound GBU-62 bomb into a guided weapon. The kit consists of a tail unit affixed to the rear of the bomb that contains an inertial navigation system, GPS module, steerable fins, and a autopilot. Around the bomb's body is a series of strakes that provide a measure of lift to extend the glide range. At a optimal release altitude, the JDAM-ER can attain a range of 46 miles. Another tool in the Ukrainian Air Force's arsenal is the similar French AASM 250 HAMMER (see the link below for more information).

     Other systems of the MiG-29 include a Phazotron NO19E Rubin airborne radar for target tracking and engagement (maximum search range of 93 miles), OEPrNK-29 series optronic Infrared Search and Track (IRST) system (9 mile range), digital fly-by-wire flight controls, SPO-15LM Beryoza RWR (Rear Warning Radar), Gardeniya-F1U jammer, SRZP-1 IFF (Identification, Friend or Foe), SRO-1P transponder, SN-29 navigation system, SUO-29M weapon selector, ILS-31 HUD (Heads-Up Display), FKP-EU gun camera, and the Schchel-3UM-1 helmet-mounted target designator.

As a side note, the MiG-29 Fulcrum C is nicknamed the “Gorbatov”, or “Hunchback”, due to the expanded and extended spine of the airframe to accommodate additional fuel capacity. It is also sometimes called the “Fatback”.

     From the opening of the Russo-Ukrainian War in February 2022 to date, the 40th. Tactical Aviation Brigade has lost ten MiG-29 fighters during combat sorties at the cost of eight pilots. The most notable non-combat unit loss was Major Andrii Pilshchykov, call sign “Juice”, who was killed during a mid-air collision with another jet during training on August 25, 2023. He was flying a Aero L-39M1 Albatross trainer. Pilshchykov was a very public advocate for the push for Ukraine to receive General Dynamics F-16 fighters and he was also a philanthropist in obtaining equipment to outfit Ukrainian pilots.

Vultee A-31 Vengeance: Training Mishap

(Author's Collection)

     A Vultee A-31 Vengeance after a belly landing, waiting for recovery. The Vengeance was a dive-bomber originally designed to meet a requirement for the French Armée de l'Air and suitably impressed with the aircraft, submitted an order for 300 examples with delivery to begin on October 1940. However, the fall of France in June 1940 put an end to the order. Fortunately for Vultee, the British were seeking a dive-bomber as well, having seen the success of the German Junkers Ju 87 “Stuka” first hand. In short order, Vultee had a new order for 300 aircraft. 

     Following the U.S. entry into World War Two, the U.S. Army Air Force (USAAF) repossessed any available Vengeance and soon requested Vultee to produce more for both the USAAF as well as for Lend-Lease. The Vengeance was flown by the Royal Air Force (almost all in the Burma Theater of operations with others serving as target tugs), the Royal Australian Air Force, Brazil, and the Free French Air Force. 

     The U.S., however, never deployed the Vengeance into combat. Instead, the aircraft it possessed served as trainers and target tugs. USAAF Vengeance aircraft were devoid of any weaponry and often, like this one, carried little in the way of markings. This particular Vengeance was likely utilized as a training aircraft as it does not appear to be carrying high visibility paint which was typical of target tugs. Brazil was the last operator of the Vengeance, removing them from service in 1948.

Messerschmitt Me 410A-1/U1: 2. Staffel (Fern)/Aufklärungsgruppe 122

(Author's Collection)

     In August 1943, a Messerschmitt Me 410A-1/U1 carrying the identification code of 'F6+WK' on the fuselage was captured intact by the British in Trapani, Sicily. The aircraft belonged to the 2nd. Staffel (Fern) of Aufklärungsgruppe 122 (2.(F)/Aufkl.Gr.122; 2nd. Squadron (Remote), Reconnaissance Group 122) that had been based at Trapani from January 1942 to June 1943. 2./Aufkl.Gr.122 was stood up on January 4, 1936 and conducted reconnaissance missions against the British Isles in 1939 flying Dornier Do 17 and Heinkel He 111 aircraft. During the 1940 campaigns against France and the Low Lands, the squadron had transitioned to the Junkers Ju 88 and the Messerschmitt Me 110 and as the war shifted to the Eastern Front, the squadron was exclusively flying the Ju 88. Starting in May 1943, the squadron received a number of Me 410A-1/U1 aircraft to supplement their Ju 88s.

     The Me 410, nicknamed the “Hornisse” (“Hornet”), was the evolution of the earlier, unsuccessful, Me 210 which was supposed to be the successor to the Me 110 heavy fighter. However, delays in development didn't see the type enter production until January 1943 and it never fully replaced the Me 110. Power came from two Daimler-Benz DB 603A 12-cylinder, inverted-V, liquid-cooled engines, each generating 1,750 horsepower for take-off and 1,625hp at 18,700ft. This gave the Me 410 a maximum speed of 388mph at 21,980ft. in altitude. The A-1/U1 model was a modification of the Me 410 from heavy fighter to that of a fast photo reconnaissance aircraft. This involved the removal of the two 7.9mm MG 17 machine-guns from the nose to allow for the fitting of either a Rb 20/30, Rb 50/30, or Rb 75/30 camera. This left the forward firing armament of two 20mm MG 151 cannons, each with 350 rounds. Fitted to each side of the fuselage was a barbette-mounted 13mm MG 131 machine-gun which was remote controlled and provided a measure of rear defense. Each of these machine-guns was provided with 500 rounds of ammunition.

     Following the capture of 'F6+WK', it was found to carry the Werknummer (Work Number) of W.Nr. 10018. This aircraft was built at Messerschmitt's Augsburg facility and it had the radio call sign of 'DI+NN'. It was decided to keep the aircraft for evaluation and so it was ultimately given the Foreign Equipment number of FE-499. After being prepared for shipment, it was placed aboard a transport and sent to the United States and arrived at Wright Field in Dayton, Ohio in January 1944. On April 1, 1944, FE-499 was still in a disassembled state in Hanger Three and it would not be until October 4, 1944 was it finally fully assembled. At some point, FE-499 was sent to Freeman Army Airfield (located in Seymour, Indiana) which was the location of the Foreign Aircraft Evaluation Center (FAEC), the latter established at the airfield on June 11, 1944. That FE-499 was there came from an inventory book that listed it on May 17, 1946. However, FAEC was soon stood down by mid-1946 as there was little need for it any longer. Nevertheless, records still showed FE-499 at Freeman Army Airfield on August 1, 1946 where it was designated as a display aircraft. It is believed to have been transported to Air Technical Service Command's storage facility in Park Ridge, Illinois and ultimately, it ended up in the hands of the National Air and Space Museum where it remains today, housed in unrestored condition at the Paul E. Garber Preservation, Restoration, and Storage Facility located in Silver Hill, Maryland.

     Source depending, FE-499 has been listed as a Me 410A-3 model, which was the definitive photo reconnaissance version which carried two cameras rather than one. It was not possible for 2.(F)/Aufkl.Gr.122 to have had the Me 410A-3 as the type was not received by units until October 1944, long after 2.(F)/Aufkl.Gr.122 had left Trapani (though it remained in Italy, based in various locations, until May 1945). In any case, only 1.(F)/Aufkl.Gr.122 and 3.(F)/Aufkl.Gr.122 ever received any of the Me 410A-3 models. Also, some sources claim that FE-499 was a Me 210 that was brought up to Me 410 standards. This was done to many Me 210 airframes and in some cases, Me 210 aircraft were built from the outset as Me 410. However, it is believed that none of these conversions were used outside of development testing for the Me 410 program, equipment trials, and armament trials. A review of Heinz Mankau and Peter Petrick's book Messerschmitt Bf 110/Me 210/Me 410 published by Aviatic Verlag in 2001 does not list the Werknummer 10018 in their roster of known Me 210 and Me 410 work numbers and in any case, most of the work numbers which began with 100XX were listed as Me 410 models with construction dates in 1943 whereas most of the conversions were done in 1942. Still, there are gaps in Mankau and Petrick's lists so we have to assume that the work number for FE-499 is accurate though it could be disputed that it is a converted Me 210.

     As a note, the unit emblem for 2.(F)/Aufkl.Gr.122 consisted of a blue shield upon which was a man wearing black boots and khaki shorts, a wide brimmed hat, and a shirt riding on a black bomb with a bellows camera under one arm. Beneath this was the motto “Holzauge sei wach!” which literally means “Wooden Eyes Be Aware!” but a more contemporary translation is “Keep Your Eyes Peeled!” This emblem was located on the left side of the forward fuselage.

Convair B-36D Peacemaker: No Match for Mother Nature

(Author's Collection)

     At 6:42pm on September 1, 1952, a tornado tore through Carswell Air Force Base (AFB) which was located northwest of Fort Worth, Texas. Among other units, stationed at Carswell was the 11th. Bombardment Wing, which had been activated back in February 1951 and under the 8th. Air Force. The wing flew the enormous Convair B-36 “Peacemaker” bomber which had the nickname of the “Aluminum Overcast” and to which Lt. General James Edmundson once described flying the massive aircraft as “sitting on your porch and flying your house around.” The tornado, boasting sustained wind speeds of over 90mph, struck the B-36 flight line directly and commenced to tossing the huge bombers about with ease. Two-thirds of the entire B-36 fleet was put out of service with some 72 bombers being damaged. 

     The only complete loss was B-36D “2051” (Serial No. 44-92051) shown in the photograph. The tornado easily lifted the bomber from its parking spot so that it came to grief off the tarmac. The encounter with the tornado snapped the tail off, broke a wing, and stripped off engine cowlings and other pieces of the airframe. Around the clock repairs would see the 11th. Bombardment Wing back to full strength by October 1952. The remains of “2051” were removed from Carswell AFB and utilized as a ground target for nuclear weapon testing. Of note, the 8th. Air Force badge can be seen on the tail. Also of note, Carswell AFB was closed in 1994 and is now the Naval Air Station Fort Worth Joint Reserve Base.

The Lloyd 40.05: Strange Solution for a Common Problem


     Until the introduction of Anthony Fokker's Stangensteuerung (literally Rod Control) interrupter gear in 1915 which allowed for a forward firing machine-gun to fire through the propeller arc with some measure of safety, the various combatants of World War One had to use other solutions to permit a machine-gun to fire forwards. At first, pilots and observers used pistols and rifles against enemy aircraft but soon after, machine-guns became the standard aircraft armament. A simple solution, used by the Nieuport 10 as an example, mounted a Lewis or Hotchkiss machine-gun on top of the upper wing, firing forwards. While clearing the propeller arc, the position of the machine-gun made reloading a difficult prospect for the pilot. Another solution was to put the engine in the rear of the fuselage. Pusher designs, such as the de Havilland D.H.2 and Farman F.40, permitted a clear field of fire for the gunner who was positioned in the front of the aircraft, forward of the pilot. Yet another relatively common solution was the use of wedge shaped deflector plates fitted to the back of the propeller that would deflect bullets away from the blades. One type of aircraft that used these deflectors was the Morane-Saulnier L scout plane. While somewhat effective, there was no guaranty that the deflected bullets wouldn't strike the aircraft. Perhaps the most bizarre solution in order to permit a machine-gun to fire forward and not destroy the propeller in the process was put forward by the Hungarian Lloyd Repülőgép és Motorgyár Részvénytársaság (Lloyd Aircraft & Motor Works, Inc.) company.

     The Lloyd Works (Ungarische Lloyd Flugzeug und Motorenfabrik AG in Austrian) manufactured the Lloyd C.II, C.III, and C.IV two-seat, single-engine biplane reconnaissance aircraft for the Kaiserliche und Königliche Luftfahrtruppen (K.u.K. LFT;Austro-Hungarian Aviation Troops). The C-series of aircraft were quite conventional in design which made the appearance of the Lloyd 40.05 (it was also called the FJ for Flugzeug Jäger or Aircraft Hunter) all the more striking when it commenced development in 1915. A Lloyd engineer by the last name of Melczer decided that an optimum solution to permit a forward firing machine-gun a good range of fire and still retain a tractor propeller (meaning, a front mounted engine) was to position the observer/gunner above the upper wing. To accomplish this, the entire forward portion of the Lloyd 40.05 featured a fully enclosed position that consumed the space between the fuselage and the upper wing. On the left side of the enclosure were clear panels to give some measure of side vision for the observer when seated and performing reconnaissance tasks. At the top of the enclosure was the open gun station which had a short windscreen in the front and armament consisted of twin 8mm M.07/12 Schwarzlose machine-guns on a flexible mounting. Just beneath the windscreen, in the direct front of the aircraft, was a radiator for the motor. While the observer had a clear view when manning the gun station, the same could not be said for the pilot. Sitting directly behind the observer's enclosure, the pilot had no forward view unless he moved his head to look from side to side. To add to the pilot's situation, the exhaust stacks for the engine were positioned on the right side of the enclosure, directly in line with the pilot's head which meant the slipstream likely carried any fumes and smoke into his face.

     The Lloyd 40.05 was powered by a MAG-Daimler 6-cylinder, water-cooled, inline piston engine that developed 160 horsepower. It drove a two-bladed, fixed pitch wooden propeller. The aircraft stood at 10.2 feet high, was 22.8 feet long, had a maximum wingspan of 36.8 feet, and a total wing area (top and bottom wings) of 270 square feet. The fully loaded weight was 2,120 pounds. The maximum service ceiling was 16,404 feet and the maximum operational range was 310 miles.

     The first prototype of the Lloyd 40.05 took to the air in January 1916 and needless to say, the K.u.K. LFT was not impressed with the design and flat out rejected it. The reasons were many and included poor handling in the air, the difficulty for the pilot to land the aircraft, slow speed due to the friction drag produced by the large frontal surface area of the plane, and that by 1916, interrupter gears were being used more and more, removing the need for other solutions to provide safe forward weapon firing. Lloyd, in a desperate bid to try to interest the K.u.K. LFT in the aircraft, converted the 40.05 into a single-seat fighter, eliminating the observer and in place of the gun station, a Type-II VK (Versuchs Kompanie) gun container was fitted, firing forward, with a single 8mm M.07/12 Schwarzlose machine-gun. The shape of the container earned the Type-II VK the morbid nickname of “Kindersarg” or "Children's Coffin”. Since the 40.05 was relatively unchanged outside of the modification to fit the gun container, the K.u.K. LFT again quickly rejected the aircraft as all the flaws of the two-seat version remained. In all, only two Lloyd 40.05 aircraft were built.

Douglas B-26B Invader "Brown Nose": 731st. Bombardment Squadron

(Author's Collection)

     A Douglas B-26B Invader belonging to the 731st. Bombardment Squadron (BS), 3rd. Bomb Group (BG). Prior to 1948, the aircraft was designated A-26B. The 731st. BS (at this time, part of the 452nd. BG), a U.S. Air Force (USAF) Reserve unit stationed near Long Beach, California, was activated for duty in the Korean War. The squadron flew their B-26Bs across the Pacific, landing at Iwakuni Air Force Base (AFB) in Japan in November 1950. 

     Upon arrival, the unit was placed under the 3rd. BG. “Brown Nose” and other 731st. B-26B aircraft conducted 2,000 sorties amounting to 9,000 flying hours from November 1950 to June 25, 1951. After that date, the 731st. was inactivated and became the 90th. BS which moved to Yokota Army Airfield (also in Japan). The extensive sortie tally on “Brown Nose” while flown with the 731st. was removed after the transfer. The 90th. would eventually be rotated back to the U.S. but not before they amassed numerous missions with a specialty for targeting rail lines (especially with trains on them) as well as marshaling yards. “Brown Nose” would be later upgraded to the B-26K standard which featured more powerful engines but removed the wing mounted machine guns. 

     “Brown Nose” would see action in the early years of the Vietnam War and on May 1966, the USAF changed the B-26K designation to A-26A. The A-26A was retired from service in 1969 when their airframes reached their maximum airworthiness level.

Consolidated B-24J "Ho Hum": 400th. Bombardment Squadron


     “Ho Hum”, a Consolidated B-24J (#42-109983) of the 400th. Bombardment Squadron (BS; the “Black Pirates”), 90th. Bombardment Group (BG; the “Jolly Rogers”). The 400th. BS was activated on April 15, 1942 and soon moved to Willow Run Airport near Ypsilanti, Michigan to commence conversion training on new model B-24 bombers (at this time, the B-24D). By the close of 1942, the 400th. BS was flying missions out of Queensland, Australia. Japanese targets in Palau, southern Philippines, New Guinea, and others felt the iron rain delivered by the “Black Pirates.” In January 1945, the 400th. BS moved to the Philippines, flying out of McGuire Field which was located on the Philippine island of Mindoro. From there, targets included Luzon and Formosa among others. The war, however, would end for “Ho Hum” and most of her crew on April 8, 1945. 

     Shortly after take-off for a mission against Japanese targets near Shinchin, Formosa, “Ho Hum” exploded and crashed into the waters off Penden Island. Rescue personnel who rushed to the scene were able to save 2LT Andre L. Sikes, SSG Drezol W. Gault, and SGT Richnel J. Shaut but the rest of the crew went down with the wreckage and their bodies never recovered. Killed were 2LT William P. Boceal, 2LT James C. Kotsakos, 2LT Charles F. Sinning, TSGT Alfred R. Foterson, TSGT Walter J. Schneider, SSG Adrian V. Tapscott, and CPL William G. Hatley. The survivors, all of which were classified as being in serious condition, were likely taken to one of the evacuation hospitals located in the Philippines (probably the 92nd. Evacuation Hospital) where they were stabilized and treated until they could safely be flown to the 13th. Station Hospital in Townsville, Australia to complete recovery. The cause of the explosion was determined to have been due to a failure somewhere in the fuel transfer system which moved fuel from one tank to another (a B-24 had eighteen fuel tanks).

     Today, the former site of the 13th. Station Hospital is partly occupied by the Holy Spirit Primary School. McGuire Field is today the San Jose Airport, having opened in 1951 following a renovation of the former airfield facilities after the abandonment of the field by the U.S. when World War Two ended. The 400th. BS was deactivated on January 27, 1946. It would be reactivated as the 400th. Missile Squadron on July 1, 1964 before being deactivated again on October 4, 2005. During these years, the unit was equipped with the LGM-30B Minuteman I, LGM-30G Minuteman III, and finally the LGM-118 Peacekeeper (better known as the MX Missile).

Consolidated B-24H “Darling Darlene”: 826th. Bombardment Squadron


     The Consolidated B-24H “Darling Darlene” belonged to the 826th. Bombardment Squadron, 484th. Bombardment Group, 49th. Bombardment Wing, 15th. Air Force. The bomber carried the serial number 42-52633. The nose art was painted by Joseph Dickman. Legible crew names include LT W.D. Rowland (navigator) and LT J.J. Petrie (co-pilot). The position behind the co-pilot was the radio operator/top turret gunner. The bomber was one of the original assigned to the 826th. BS and her crew chief was James Jones, Jr. The bomber was flown to Torretto Field on March 20, 1944. The airfield opened on February 1944 and was located a little under 9 miles from the Italian town of Cerignola. It would serve as the base of operations for the 484th. BG. The 826th. BS conducted long range bombing missions into Italy, France, Austria, Germany, Czechoslovakia, and Hungary, striking Axis infrastructure and military targets. 

     While on a mission on June 9, 1944, “Darling Darlene” suffered combat damage while over Munich, Germany which caused one engine to fail. The bomber put down at Vis Air Base on the Croatian island of Vis. Repairs were effected there and the bomber would return to Torretto Field. “Darling Darlene” would survive the war, returning to the U.S. on May 29, 1945. Torretto Field would be shut down and abandoned on August 1945, the land returned to agricultural use. 

     The 826th. BS would shift roles in May 1945 when it came under the control of Air Transport Command, the B-24s used as ferries for personnel and cargo transport. In July 1945, the 826th. was stood down.

Consolidated Liberator B Mk.VI "V-Victor": Accident Over Monfalcone

     British bomber crews, like their American counterparts, faced a multitude of dangers. Enemy fighters and fighter-bombers, anti-aircraft fire, and even mechanical issues all posed hazards. But another danger was “friendly fire” accidents and this photograph is evidence of that. On March 16, 1945, the Consolidated Liberator B Mk.VI (the British designation for the B-24H) “V-Victor” (code KK320) of No. 37 Squadron RAF (Royal Air Force) was part of a bombing raid on the ship and marshaling yards in Monfalcone, Italy. “V-Victor” was piloted by Squadron Leader Lionel C. Saxby while other members of the eleven man crew included Pilot Officer (P/O) G.T. Barker (navigator), K.H. Westrope (tail gunner), Wally Lewis (top turret gunner), and Cliff Hurst (radio operator). Included in the raid were bombers from No.70 Squadron RAF of which one of the aircraft was another Liberator B Mk.VI, “R-Roger”. Both squadrons were part of No.231 Wing RAF which itself was part of No. 205 Group RAF, flying out of Tortorella Airfield in Italy. As the bombers reached their targets over Monfalcone, at 12,000ft., they began to release their payloads that consisted of 1,000lb GP (General Purpose) bombs. It isn't exactly known if “R-Roger” or “V-Victor” drifted from formation but the pilot of “R-Roger” was not aware “V-Victor” was now almost directly underneath them.

     Two bombs from “R-Roger” struck “V-Victor”. The first bomb hit directly on the top turret, shattering it while crumpling the upper fuselage, and then passed through the fuselage, creating a significant tear in the aluminum skinning. Fortunately for Wally Lewis, he had not been manning the turret at the time but was actually struck by the bomb as it passed through the fuselage, the glancing blow enough to render him unconscious. Cliff Hurst, whose radio station was located near the turret, suffered numerous small injuries from the shards of metal that whipped through his compartment, helped by the buffeting winds howling through the shredded fuselage. The second bomb struck the port, inner engine, buckling the cowling to the point the winds ripped away several pieces. The bomb also skidded off the cowling and knocked the propeller off in addition to causing the engine to trail smoke. Immediately after the hits, “V-Victor” quickly lost altitude and entered into a dive. Some of the crew made ready to abandon the stricken plane but Squadron Leader Saxby was able to recover from the dive and piloted “V-Victor” back the 300 miles to Tortorella Airfield, landing the bomber without incident. The photograph shows “V-Victor” after landing, the crew and maintenance men examining the damage. Baxby can be seen in the fuselage gash while the navigator, P/O Barker, is looking over the wrecked turret from a hatch while a mechanic assesses the extent of the engine damage.

     Although the damage was significant, it wasn't too severe that it could not be repaired. However, “V-Victor” was written off on April 26, 1945. In part, the decision to not repair the Liberator could have been due to the fact that the squadron was relocating to Aqir, Palestine beginning on October 2, 1945 and not long after, in December 1945, moved to Shallufa, Egypt where No.37 Squadron was eventually stood down on March 31, 1946.

Northrop P-61B-1 "The Spook": 548th. Night Fighter Squadron

(U.S. Army Signal Corps)

     On April 20, 1945, the Northrop P-61B-1 Black Widow (serial number 42-39405) named “The Spook” was returning to Central Field located on Iwo Jima following a night patrol. Aboard was pilot Lieutenant Melvin Bode, radar operator Lieutenant Avery J. Miller, and gunner Staff Sergeant John Hope. “The Spook” was part of the 548th. Night Fighter Squadron (NFS), 7th. Air Force and tasked with performing combat air patrols and nocturnal escort operations for the Boeing B-29 Superfortresses of the 20th. Air Force flying out of both Saipan and Iwo Jima. Heavy fog obscured the landing field and so Lt. Bode decided to make a blind landing with the assistance of the airfield's AN/MPN-1 unit. The AN/MPN-1 (Mobile, Pulsed, Navigation aid) consisted of a 2 ½-ton 6x6 truck that mounted two PE-127 power units, an air conditioning unit, and spare parts for the radar trailer it towed. The trailer contained a radar set that provided range and azimuth data out to 30 miles and up to 4,000 feet in ceiling. In addition to the radar, the trailer housed HF (High Frequency) and VHF (Very High Frequency) communication to aircraft via a SCR-274 transmitter and BC-342 receiver. The operator, who had a booth inside the trailer, provided guidance to the pilot based on the radar readings. Unfortunately, “The Spook” was caught by a strong cross wind during the landing, causing the plane to drift. It clipped a parked P-61B (“Anonymous III”) before belly landing off the main runway. No injuries were sustained but it was the last flight for “The Spook” as the damage was too extensive to repair and so the aircraft was written off. The last entry known for “The Spook” was on June 6, 1949 where the aircraft was checked into Clark Field in the Philippines for reclamation (ergo, scrapping).

     The 548th. NFS was a fairly short lived unit. Activated on April 10, 1944, the unit deployed to Central Field, Iwo Jima in late January 1945 following months of training, patrol missions around Hawaii, and having to wait for their P-61 aircraft to be modified for operations in the Pacific Theater. Arriving at Central Field by the close of February 1945, the unit commenced long range patrols over the ocean. On several occasions, aircraft of the 548th. NFS encountered Imperial Japanese Air Force (IJA) Mitsubishi G4M bombers that more often than not, upon seeing the P-61s, jettisoned their payload and retreated. While this did not make for many kill scores for the unit, they were a deterrent which protected the airfields from attack. On June 13, 1945, the unit relocated to Ie Shima island near Okinawa and conducted nocturnal patrols over the Okinawa area and towards the end of the war, shifted to nocturnal intruder raids and conducting weather observations for B-29 bombers raiding the Japanese home islands. When the war ended, the ground personnel were reassigned to the Army of Occupation in September 1945 while the unit's aircraft were put into storage in Okinawa and Clark Field in the Philippines. All told, the 548th. NFS downed five enemy aircraft: three Mitsubishi G4M bombers, one Nakajima Ki-44 fighter, and one Nakajima A6M2-N floatplane. On December 19, 1945, the unit was inactivated. The unit was revived again as the 548th. Special Operations Training Squadron from October 15, 1969 to July 31, 1973 where the unit training pilots and crews of the Republic of Vietnam Air Force in how to fly and operate the Douglas C-47 Skytrooper, AC-47 Spooky gunship, and to a lesser extent, the EC-47 Phyllis Ann electronic warfare aircraft. For a third time, the unit was revived, this time as the 548th. Combat Training Squadron on July 1, 1994 and it remains active to this day out of Barksdale Air Force Base in Louisiana with a detachment based at Fort Polk, Louisiana.

     As for the P-61, it was the only “built from the ground up” night fighter deployed by the Allies during World War Two. It was powered by two Pratt & Whitney R-2800 Double Wasp 18-cylinder, air-cooled, radial piston engines that drove 4-bladed Curtiss Electric constant-speed propellers. These engines gave the P-61 a top speed of 366mph at 20,000 feet. Armament consisted of four 20mm AN/M2 Hispano cannons in a ventral tray with 200 rounds per gun and four .50 caliber M2 Browning machine-guns in a remotely operated, 360 degree traverse upper turret with each gun provided with 560 rounds of ammunition. For ground attack, the P-61 could carry up to four bombs up to 1,600 pounds each or six 5” HVAR (High Velocity Aircraft Rocket) unguided rockets. Avionics included the SCR-720 search radar and the SCR-695 tail warning radar. A total of 706 examples of the P-61 were built and the type was retired from service in 1954. Only four aircraft are known to exist today and includes a P-61C-1 (serial number 43-8353) on display at the National Museum of the U.S. Air Force at Wright-Patterson Air Force Base in Dayton, Ohio. It is painted in the livery of “Moonlight Serenade”, a P-61B-1 that was operated by the 550th. NFS.

     Finally, as a side, the coloration of “The Spook” was all black with red propeller spinners and cowl flaps with the propeller tips in yellow. The underside of the nose had a smiling pair of lips in red with white teeth, a white eye with a black dot and green iris with a gray bottom eyelid on either side of the nose and on the front, a white outline of a stylized human nose. The name of the aircraft consisted of “The” in white cursive with “Spook” in white with both of the “o” in the name being angry eyes with gray irises inside each “o”.

 

Northrop P-61A-1 "Nightie Mission": 6th. Night Fighter Squadron

(U.S. Army Signal Corps)

     The Northrop P-61 Black Widow was the first dedicated night fighter to be built and deployed by the U.S. Army Air Force (USAAF). It was also the first fighter to be designed with internally mounted radar equipment. Heavily armed with four forward firing Hispano M2 20mm cannons in the fuselage and a dorsal turret equipped with four Browning M2 .50cal. machine-guns, the P-61 saw service in all theaters in World War Two. 

     This photograph depicts “Nightie Mission”, a P-61A-1-NO belonging to the 6th. Night Fighter Squadron (NFS), being serviced in preparation for a mission. Sent to the Pacific Theater, the 6th. NFS operated from Saipan with the first sortie being flown on June 25, 1944. The primary mission of the 6th. NFS was to defend the Saipan airfields from Japanese attack given that Boeing B-29 Superfortresses were using Saipan as a launch point for attacks against the Japanese main islands. The 6th. NFS had a long history, being activated in 1917 then stood down in 1947. However, in 2017, the unit was reactivated as the 6th. Weapons Squadron and will be equipped with the Lockheed-Martin F-35A Lightening II for the purposes of generating weapons instruction material for pilot training. 

     Returning to “Nightie Mission”, pilot 1LT Francis “Lil Ab” Eaton, Radar Operator 2LT James “Chief” Ketchum, and gunner S/Sgt. William Anderson, III claimed a kill of a Mitsubishi G4M “Betty” bomber on July 7, 1944. This would be the only kill “Nightie Mission” was to achieve. The aircraft was written off on August 5, 1945 due to extensive damage caused on the ground by a typhoon.

The Messerschmitt Me 163B-1a: A Captured Komet

     The Messerschmitt Me 163 “Komet” was the world’s first operational rocket fighter, entering combat for the first time with the test unit Erprobungskommando 16 on May 13, 1944. Because of the highly limited endurance (7.5 minutes of powered flight), the Me 163 was deployed as a point defense fighter, flying from bases close to known Allied bomber flight paths. The high speed while under power meant interception of the Me 163 was difficult at best. The combat service of the Me 163, taken as a whole, was underwhelming. When Me 163 bases were discovered, bombers would simply fly around them, out of range of the Komet. The high speed, while giving defending escorts fits, meant the Me 163 pilot had mere seconds to line up a bomber, fire, and bank away to avoid collision. Only the most skilled pilots could achieve hits. Finally, once the fuel was used up, the Me 163 was no more than a glider and so the Allied fighters would attack Komet bases before the Me 163s could sortie or would simply wait until the Me 163s expended their fuel and would “bounce” them as they glided back to their base.

     This particular Komet, a Me 163B-1a (the type most deployed in combat), belonged to II.Gruppe of Jagdgeschwader 400 (JG 400) [II/JG 400]. It carried the Werk Nummer (Work Number) 191301 and was captured by the U.S. and given the Foreign Equipment (FE) number 500 (FE-500). The plane was sent to Freeman Field in the U.S. and while there, was refurbished to make it ready for flight testing. On April 12, 1946, FE-500 was air freighted in a Fairchild C-82 Packet to Muroc, CA (now Edwards Air Force Base). Once there, the FE number was replaced with a “T-2” number after the Technical Data Laboratory (which evaluated Axis aircraft) became part of the T-2 Intelligence section. Starting on May 3, 1946, T-2-500 underwent numerous unpowered gliding flights, being towed into the air by a Boeing B-29 Superfortress. Nearly all of the flights were carried out by Gustav E. Lundquist (seen here in the cockpit). T-2-500, although the highly reactive fuels T-Stoff and C-Stoff were available, did not fly under power as it was discovered that the laminate on the wooden wings was failing and so T-2-500 was put into storage, ending up in Silver Hill in 1954. 

     The aircraft was put on public display in unrestored condition but in 1996, the aircraft was lent to the Mighty Eighth Air Force Museum who restored the Komet. In 2011, it was returned to the Smithsonian and is currently on display at the Steven F. Udvar-Hazy Center in Chantilly, Virginia.
