soviet naval 45mm 21k 3D Model

detailed, high-poly model of a soviet 45 mm anti-aircraft '21k' with textures and materials

the 45 mm anti-aircraft 21-k was a soviet design adapted from the 45 mm anti-tank m1937 53-k. this was a copy of a 3.7 cm 1.5 in german designed by rheinmetall that was sold to the soviets before hitler came to power in 1933 that had been enlarged to 45 mm 1.8 in in increase its penetrating power. it was used by the soviet navy to equip almost all of their ships from 1934 as its primary light anti-aircraft. it was used in world war ii and during the cold war as the soviets exported their wwii-era ships to their friends and allies. however it was not very effective as its slow rate of fire and lack of a time fuze required a direct hit to damage targets.
