Soviet Union's A-32 and T-32 medium tank

Design

Designed along side the A-20, A. A. Morozov and M. I. Koshkin worked on another design that would be simpler to produce and maintain.5

The T-32 was to only be able to run on tracks.5,7

Prototype

In August 1938 the High War Council, let by People's Commissar for Defense, K. J. Voroshilov, discussed the A-20 and T-32.6 Many on the Council disliked the T-32 as it didn't have the wheel track feature they were wanting.6,7 Stalin however saw the validity of Koshkin's argument and backed the A-32.7 In July 1939, the Kharkov Locomotive Factory had completed the prototypes for the A-20 and T-32.5,6 They were both then tested and it was decided to go with the T-32.5 On December 19, 1939, the People's Commissariat for Defense released the T-32 to the Red Army.6,7 It was soon designated the T-34.6

In 1939 tests were conducted with the T-32 and A-20 and the T-32 was selected as it had better fire power and armor.4

Variants

  • A-32: Based on the A-20 but the main armament was upgraded to 76.2 mm in 19393,4 Ran on wheels or tracks.7
  • T-32: Produced in 1939 and very similar to the A-32, but it no longer had a wheel mode.3,4
