Fruit of Compromise
The T-34-85 was a very modern tank at the end of WWII, but it was no secret that the tank would soon be obsolete. The Czechoslovakian military realized this too. On October 17th, 1945, a meeting of the General Staff was held where its commander, Divisional General Bohumil Boček approved the tactical-technical requirements for the Tank všeobecného použití (TVP), a main battle tank. The requirements were clearly inspired by the T-34-85, but the implementation details varied significantly.
Development of the TVP was behind schedule. The military-technical institute (Vojenský technický ústav, VTU) where the tank was being developed presented a concept in March of 1946. CKD and Skoda were supposed to develop their own tanks based on it. The result was the Skoda T 40 project, a significantly different tank from the initial TVP. This project, presented in December of 1946, was already unsatisfactory by next year. As a result, the TVP was reworked in 1948, and resulted in the Skoda T 50 and CKD T 51. SPGs were also designed on the chassis of these tanks.
