Char B1 bis (n° 416) “Hautvillers”: Knocked Out at Stonne

Source: Reddit

     Looking at a map of France, today the village of Stonne is a tiny speck consisting of 2.77 square miles of land area and 39 residents. Yet, between May 15 and May 17, 1940, Stonne was the epicenter of a brutal see-saw battle between an ad-hoc force of French Army troops and the German Army, led by the 10th. Panzer Division along with other elements, to include the crack Infanterie-Regiment "Großdeutschland".

     While Stonne itself had absolutely no military value, the land it was situated on most certainly did. Immediately to the north of Stonne sits Mont-Dieu (God's Mountain) which is heavily wooded with only the D 30 road running through it and into Stonne. The village itself sits atop a 330 meter (1,082 foot) elevation with a very steep drop-off into the thick woods north of the village. To the east of Stonne, near the D 30 road's turn into the village, is Le Pain de Sucre (Sugarloaf) which is a conical shaped hill some 335 meters (1,099 feet) high.“Zuckerhut“ (also meaning Sugarloaf), as the point was called in German, offered an excellent observation point. The French realized that the area around Stonne was a natural obstacle to check the German advance further south and so they quickly fortified the area with pillboxes and set up barriers to slow down German troops.

     During the Battle of Stonne, the village exchanged hands seventeen times. The initial day saw elements of the 3e Division d'Infanterie Motorisée already positioned in Stonne but by 0800 hours, Stonne was in German hands, led by 1. Bataillon, Infanterie-Regiment "Großdeutschland". In the course of the day's combat, Char B1 bis tanks belonging to 3e Compagnie, 49e Bataillon de Chars, would see action against the Germans and the knocked out tank shown here was one of them. The tank, n° 416 and named “Hautvillers“, was commanded by Sous-lieutenant Jacques Klein and driven by Caporal-chef Emile Chanel. The names of the radio operator and assistant driver (who was usually a mechanic) that completed the crew are not known. The tank was received by the unit on March 25, 1940. 

     At approximately 1000 hours,“Hautvillers“ had been advancing north towards Stonne over the ground between the D 30 and D 24 roads. A Panzerkampfwagen IV, belonging to Panzer-Regiment 8, spotted the French tank and took it under fire. The Pz.IV's gunner, one Karl Koch, was able to hit “Hautvillers“ three to four times. The results of the successful engagement saw “Hautvillers“ turret jammed, the 47mm gun fitted to it bent, the right side track severed, and a non-penetrating hit on the armor near Caporal-chef Chanel's station. The spalling of the armor on the interior by the strike caused superficial injuries to Chanel and triggered a fire in the tank's electrical system. With such crippling hits, the crew abandoned the tank though all four men would later be captured by German troops. Given the photograph, it is clear the fire consumed the tank, probably causing an ammunition detonation which blew apart much of the upper hull, causing the turret to fall inward. This particular photograph was likely taken well after the battle as much of the debris following the tank's demise is no longer seen laying on the ground. Based on the many photographs taken of the tank by German soldiers, the location of the wreck may be at the intersection of Route de la Berlière (D 24) and Rue du Paquis which is located just outside Stonne proper.

     While German forces ultimately won the Battle of Stonne, the area would not be completely pacified until May 25, 1940.

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.
