Even before A.M. Ljulka started working on the jet engine, similar work was done in England and Germany, that the first jet engines were tested here in 1937 and the first flight of the jet engine took place in Germany in 1939. But all this happened in deep secrecy. So A.M. Ljulka went this route alone and is rightly considered the founder of the development of jet engines in the USSR.
The V-2 engine was installed before the war on Soviet light tanks BT-7M, medium tanks T-34 and heavy KV-1 and KV-2, as well as on a heavy crawler artillery tractor Voroshilovec. During the war, it was installed on medium tanks T-34, heavy KV and IS, as well as on cars derived from them. In the post-war years, this engine was modernized and its direct descendants are modern tank engines.
