Description


Armament

The vehicle was armed with the 5 cm PaK 38 gun with 32 rounds of ammunition and without any secondary armament. It was primary intended to by use by German airborne troops, who needed such vehicle that could be transported by plane. The 5 cm PaK 38 was mounted on top of the engine compartment, with one man on each side. A limited traverse mount allowed 40° traverse and – 10 + 20° elevation. Ammunition was stored alongside the driver in the place that was formerly occupied by the commander. To cope with the recoil loads imposed on the very small chassis, a spade was lowered at the rear of the vehicles. The armor ranged from 8 – 14.5 mm. The fighting compartment, was the area behind the antitank gun’s armored gunshield. This offered protection only from 7.92mm armor ammunition. Self-propelled gun was operated by the crew of three people: the driver he was placed inside the vehicle, gunner who was placed left of the gun and loader. who was right of the gun.


Hull and casemate

The dimensions of this vehicle were: width 1.83m, length 3.57m and height 1.44m (VK 302). Combat weight is in the range of 4.5 tons, it could reach up to 30 km/h with its Borgward 6M RTBV six-cylinder 50 hp engine, with operational range of 150 km. There is no information if any of these vehicles were equipped with a radio, and if there was any room for it. In September 1941, another light fighting vehicle prototype was ordered. This was to be armed with the 10.5 cm LG recoilless gun designed by Rheinmetall-Borsig for paratroops use. A Krupp proposal a 360° traverse turret configuration. Only one mock-up model was completed.


Production and action

It was planned to produce some 200 vehicles, but only two were ever built and these were sent off for troop trials in July 1942. However, by that time the 5 cm PaK 38 was no longer a viable anti-tank gun and the whole project was abandoned. Little is known about their combat performance.
