Russo-Ukrainian War: The 9K310 Igla-1 MANPADS

Source: General Staff of the Armed Forces of Ukraine

     A soldier belonging to Tactical Group Druzhkivka poses with a 9K310 Igla-1 (NATO reporting name SA-16 Gimlet) MANPADS (Man Portable Air Defense System) surface-to-air (SAM) missile launcher. The word “Igla” in Russian means “needle”. Tactical Group Druzhkivka is a Territorial Defense Force unit that operates in and around Druzhkivka, Donetsk Oblast where MANPADS such as the Igla-1 are useful against UAVs and drones.

     The Igla-1, which first entered service in 1981, is actually a simplified version of the 9K38 Igla (NATO reporting name SA-18 Grouse) which appeared in service in 1983. The reason for this is that development of the 9K38 was taking longer than expected  and so it was decided to push a less complex system into the field to more quickly replace the aging 9K32 Strela-2 (SA-7 Grail) and 9K34 Strela-3 (SA-14 Gremlin) MANPADS.

     That this is a 9K310 Igla-1 is denoted by the 9M313 fire-and-forget missile protruding from the 9P322 fiber-glass launch tube with its distinctive aerospike mounted on a tripod attached to the nose. The later 9K38 replaced this with a longer aerospike attached directly to the missile's seeker head. The aerospike is used to reduce drag during flight. 

     The warhead has a weight of 2.6 pounds of which .9 of a pound accounts for the HE-FRAG (High-Explosive Fragmentation) payload. The missile has two fuzes, one that will detonate the warhead on a direct impact while the second will set off the warhead from a grazing hit on the target. The missile will also attempt to strike the fuselage of the target and to add to the lethality, there is a second charge that will set off any remaining solid fuel for the motor. The seeker head contains two detectors. The first is a cooled mid-wave infrared (MWIR) indium antimonide (InSb) detector for target detection and the second is a uncooled short wavelength infrared (SWIR) lead sulfide (PbS) detector which is used to identify decoy infrared flares. Onboard logic circuits evaluate what the detectors are registering and determine if it is the intended target or flares being deployed to confuse the missile. The missile is also resistant to the U.S. built AN/ALQ-144 series of infrared countermeasure devices.

     The solid fuel rocket motor can push the 9M313 missile to a maximum speed of Mach 1.9 while the missile has a operational range of 3.1 miles with a flight ceiling of 11,000 feet. The missile rolls as it flies, imparting stability and the single set of control surfaces is operated by electrically powered pistons, the energy received from a gas turbine within the missile that is fed by a gas generator. This same gas generator can shunt exhaust over the control surfaces if needed when the airspeed is too low for effective steering. The missile's reaction time is between 5 to 10 seconds and it is capable of engaging an oncoming target with an approach speed of 1,017 feet per second or a retreating target with an egress speed of 853 feet per second.

     The bulbous object the operator's left hand is holding contains a thermal battery but more importantly, it contains liquid nitrogen coolant that keeps the MWIR InSb detector in the seeker head at optimal temperature prior to launch. The Igla-1 can be fitted with the 1L14 IFF (Identification Friend or Foe) to reduce the chance of friendly fire. The 9P519 grip stock, which also contains the 9B328 power supply unit, is detachable and can be detached from a spent launch tube and attached to a fresh one to launch another missile as long as the power supply has enough charge.

Russo-Ukrainian War: The Corsair ATGM

     A Ukrainian anti-tank team on the practice range with a “Корсар” (“Corsair”) anti-tank guided missile system. In some publications, the entire system is designated the RK-3 “Корсар” based on the nomenclature of the missiles. Speaking of such, the 107mm missile leaving the tube is a РК–3ОФ (RK-3OF) HE-FRAG (High-Explosive Fragmentation) munition, one of three missile types the Корсар is able to fire. The other two are the РК–3К (RK-3K) tandem-warhead AT (Anti-Tank) missile and РК–3И (RK-3I) inert warhead practice missile. The Корсар isn't a new system with State Design Bureau “Luch” out of Kyiv, Ukraine having commenced development in 2013. After trials, the first 50 examples of the Корсар were delivered to the Ukrainian Army in 2017. In 2018, testing with the Корсар was done using a thermal imaging camera and the final version, shown in this photograph, was accepted for service in 2020.

     The Корсар is designed to be lightweight portable missile system to facilitate not only lessen the burden of infantrymen who have to “hump” the Корсар around the battlefield but also to utilize the missile system on armored vehicles without adding unnecessary weight to the overall vehicle. The SPU-3 tripod, with the thermal imager, weighs 26 pounds while the PN-KU guidance system with the launch rail weighs 18 pounds. The average missile weight is 34 pounds. The typical Корсар crew is 2 men. The Корсар breaks down into four components: the SPU-3, the thermal imager, the PN-KU, and the launch rail. These components can be carried in nylon/water resistant backpacks while the PN-KU and thermal sight are carried in a plastic, impact resistant dry box carry case.

     The Корсар's missiles utilize SALG (Semi-Automatic Laser Guidance). SALG works by “painting” the target with a laser beam but the missile's seeker doesn't “ride” the beam towards the target. Instead, it picks up the reflected laser energy and aligns itself towards the strongest reflection. SALG is not as robust as true laser beam guidance and targets using HR (Highly Reflective) paint can affect the laser's energy reflection strength while smoke can also interfere with the laser. In addition, laser warning systems can pick up SALG laser designators. The PN-KU does utilize a low power laser to reduce the detectability by laser warning systems. Where SALG excels is in low cost, the ability to lock onto other types of laser designators (manufacturer agnostic), and the ability for the Корсар system to shift positions after launch. The latter is important given the launch signature of the Корсар which would betray the anti-tank team's location and that the operator needs to keep the target “painted” until the the missile hits. The ability to move to another location and reacquire the target without the missile instantly going out of control during the few seconds the guidance stops, even if only a few feet from the initial launch point, can increase team survivability against retaliatory fire. In regards to the backblast, injury would result to anyone within a 30 degree cone from the rear of the launch tube, out to a distance of 32 feet.

     The RK-3OF is meant to engage emplacements, soft targets, buildings, and bunkers out to a range of 1.5 miles. The thermal imager permits night engagements out to a range of 1 mile in addition to aiding in target identification. The missile is also equipped with a shock core which is a shaped charge that lets it more easily penetrate hardened fortifications made from concrete and other similar materials. The missile can also drill through 50mm of RHA (Rolled Homogeneous Armor) which makes the Корсар lethal to many IFVs (Infantry Fighting Vehicles), APCs (Armored Personnel Carriers), and IMVs (Infantry Mobility Vehicles). However, against tanks, the RK-3OF would struggle. As such, the RK-3K missile would be used to engage tanks as the missile can penetrate 550mm of RHA armor after ERA (Explosive Reactive Armor).

Russo-Ukrainian War: Supacat HMT 600 w/ ASRAAM

Source: Ministry of Defense of Ukraine

     In February 2024, a video appeared online showing this vehicle, a British Supacat manufactured 6x6 HMT 600 (High Mobility Transporter) which is fitted with a launch system for the British ASRAAM (Advanced Short Range Air-to-Air Missile; AIM-132 in U.S. service) short range missile. It was originally believed this was the British Gravehawk SAM system but more recent reports state the pictured “FrankenSAM” is not Gravehawk. The final Gravehawk system is fitted within a standard shipping container which is transported by a Leyland DAF 8x8 DROPS (Demountable Rack Offload and Pickup System) truck. It uses Soviet-era Vympel R-73 missiles that are utilized by Ukrainian Air Force fighters as short range AAMs (Air-to-Air Missiles). As there is a surplus of R-73 missiles (NATO reporting name AA-11 Archer) due to the fact air-to-air combat between Ukrainian and Russian jets is rare, the R-73 is seeing use as a SAM.

     However, the launcher on the Supacat HMT 600 is very similar to the one used on the Gravehawk, down to the shiny bolts that hold it together. In addition, the mast mounted sight is nearly identical to the one used on the Gravehawk. So, it is very possible that some of the equipment and apparatus seen here on the Supacat HMT 600 was incorporated into the final Gravehawk system.

     Returning to the ASRAAM, it entered service in 1998 and it uses a dual-burn, high-impulse solid fuel rocket motor that can accelerate the ASRAAM to speeds exceeding Mach 3 (2,300 miles per hour). The maximum range around 30 miles. For a warhead, the ASRAAM has a 22 pound HE-FRAG (High-Explosive Fragmentation) payload and it can be triggered by one of two means: proximity fuze or impact. The ASRAAM uses LOAL (Lock-On After Launch) which means it can be launched and the onboard inertial guidance system will guide the missile towards the target, making adjustments as necessary to ensure a hit. There looks to be a Chess Dynamics Hawkeye optical suite which provides targeting, tracking, and target identification for the operator. The suite can be used with the ASRAAM to bring it to bear on a target. Speaking of targets, the ASRAAM is primarily deployed against Russian drones, loitering munitions, and cruise missiles.

     As for the HMT 600, it is powered by a Cummins 6-cylinder diesel engine developing 180 horsepower and this provides for a top road speed of 75 miles per hour. The engine is paired to a Allison 5-speed automatic transmission. 53 gallons of fuel provide for a maximum cruise range of 435 miles. The cab is armored though to what level isn't stated in Supacat literature. It is also mine-resistant, in part due to the high wheelbase. Other features include ABS (Anti-lock Brake System), power steering, adjustable ride height, and four-wheel drive. As optional items, the HMT 600 can be fitted with runflat tires, self recovery winch, smoke grenade launchers, a RWS (Remote Weapons Station) mount, and IR lights.

Russo-Ukrainian War: AASM 250 HAMMER ASM

     Secured to one of the four wing pylons of a Ukrainian Sukhoi Su-25M1 Grach (“Rook”; NATO reporting name Frogfoot) is a AASM 250 HAMMER ASM (Armement Air-Sol Modulaire 250 Highly Agile Modular Munition Extended Range Air-to-Surface Missile). More simply called Hammer, the AASM is a French designed, all-weather smart weapon which first entered service with both the French Air Force and Naval Aviation in 2007. The AASM is actually a kit which is fitted to existing free-fall bombs, turning them into guided missiles. The AASM kit can be fitted to 125, 250, 500, and 1,000 kilogram bombs (hence the number in the designation). France, as part of its military aid to Ukraine, has provided Ukraine with around fifty AASM systems per month in 2024.

     The standard AASM (and likely the type provided to Ukraine) consists of a hybrid guidance system which combines a inertial navigation system (INS) with a global positioning system (GPS). This system is held within the finned nose-cap that is secured to the head of the bomb. The INS utilizes motion/rotation sensors whose input goes into a computer which constantly calculates the AASM's position, orientation, and speed. As such, it is essentially a fire-and-forget munition. However, the AASM can be fitted with a enhanced guidance suite which adds infrared homing. Without the infrared capability, the AASM can hit a target within 10 meters of the aim point. With the infrared homing, this improves to a single meter. A third option replaces the infrared homing with laser guidance system that permits on-target hits and can even allow the AASM to strike mobile targets. The second set of nose fins can rotate their angle, permitting the AASM to maneuver.

     Attached to the back of the bomb body is a  “range extension kit” which consists of a solid-fuel rocket motor and a “aerodynamic unit” consisting of four fins. When dropped at altitude, the AASM can achieve a maximum range of 43 miles but if dropped at low altitude, the range diminishes to a maximum of 9 miles.

     Assuming the usage of a U.S. Mk. 82 250 kilogram bomb (which the AASM can be fitted to), the payload is usually 196 pounds (89 kilograms) of Tritonal explosive. This results in a blast radius of 80 meters by 30 meters with a lethal area stretching out to 2,400 square meters with fragments having speeds of between 1,700 to 5,458 miles per hour.

     To date, in Ukrainian service, the Hammer is being launched from not only the Su-25 but also from Mikoyan MiG-29 fighters (NATO reporting name Fulcrum) using modified pylons.

Russo-Ukrainian War: The FGM-148 Javelin

     The ATGM (Anti-Tank Guided Missile) shown here in the hands of a soldier of the 5th. Detachment, Special Operations Center “Omega” was an absolute game changer during the opening months of the Russo-Ukrainian War which commenced on February 24, 2022. The weapon? The FGM-148 Javelin. The effectiveness was so great that it spawned the image of “Saint Javelin” (the Virgin Mary cradling a Javelin) and saw Russian tanks sprout the so-called “cope cages” (raised slat armor over the turret top) in a vain attempt to deal with the missile. Ukraine had received over 8,000 Javelin systems by February 2023 with the majority being delivered by the United States. The FGM-148 entered service with the U.S. military in 1996 and was the replacement for the M47 Dragon ATGM.

     What makes the Javelin effective is two-fold. The first is that the missile is capable of using what is called a “top attack” engagement profile. This means the missile strikes the target from above. On most tanks, the armor thickness of the top of the hull (front and rear) as well as the top of the turret is thin and thus relatively easy to penetrate. The second is that the Javelin is a fire-and-forget weapon. Once the gunner obtains a target lock, upon launch, the missile guides itself to the target.

     The Javelin is a two-part system. The main part, which is reusable, is the CLU (Command Launch Unit). The CLU is fitted with a day sight which provides 4X magnification but for night operation, the CLU has a 4X magnification thermal sight which is very sensitive to infrared radiation. The night sight also has a 12X magnification to enable the operator to identify the potential target. Once the target is identified and is to be engaged, the operator switches to a 9X magnification FOV (Field of View) for the missile's seeker. Here, the operator sets his aim and the target information is transmitted to the missile's guidance system. Once the operator sets the lock after depressing a launch trigger, the missile fires after a very short delay. The CLU has a weight of 14 pounds and a loaded missile tube is 35 pounds. The tube is single-shot and once fired, the CLU is detached from the spent tube and secured to a new one.

     The 127mm missile uses a solid fuel rocket motor which permits an effective range of 1.6 miles when used by a dismounted tank hunter team (usually two men) or, if the launcher is mounted on a vehicle, up to 2.95 miles of effective engagement range can be achieved. The 19 pound, contact fuzed warhead consists of a tandem-charge HEAT (High-Explosive Anti-Tank) payload. The first charge is designed to defeat ERA (Explosive Reactive Armor), permitting the second charge to strike the target's armor underneath. The Javelin is said to be capable of penetrating at least 760mm of RHA (Rolled Homogeneous Armor) after ERA. This is well able to defeat nearly all modern main battle tanks. Though the Javelin often uses its top attack ability, it can be fired directly at targets such as fortifications or if a armored vehicle is too close to permit a top attack. Maximum altitude for a top attack is 490 feet and for direct attack, 200 feet.
