The 40M Nimród was a World War II Hungarian self-propelled anti-aircraft gun based on a license-built copy of the Swedish Luftvärnskanonvagn L-62 Anti II tank. Originally, it was intended to be used both in the anti-aircraft and tank destroyer roles, but it proved to be ineffective against Soviet tanks like the KV-1 tank. Therefore, it was primarily utilized against lightly armored vehicles and for air defense.
The 40M Nimród was based on the chassis of the Hungarian 38M Toldi
tank, which was itself based the Swedish Landsverk L-60B
tank; however the chassis of the Nimród was longer. The vehicle had a crew of six men: commander, driver, two loaders and two gunners.
The vehicle's only armament was a 36M 40 mm Bofors
anti-aircraft gun also made in Hungary
under license. The gun fired the usual anti-aircraft ammunition as well as a Hungarian anti-tank
round. It had a rate of fire of 120 rounds per minute and a penetration of 46 mm at 100 m and 30 mm at 1000 m. The Nimrod carried 160 rounds.
Late in the war, the vehicle was issued with the 42M "Kerngranate" round. This was a rocket grenade fitted over the muzzle in the fashion of a rifle grenade.
