In the early 50s USSR started developing an ARV build on the hull of T-54 that was just entering production. A prototype vehicle was completed after a short while and was named BTS-1 (BTS - Bronirowannyj Tjagacz Sriednij). Production was launched and it became the basic ARV of the soviet army.
In 1955 BTS-1 was upgraded with a hoist and a small folding crane. This upgraded version was given name of BTS-2. It was build on the T-54 hull and later on the T-55 hull. In the end of the 60s Poland and Czechoslovakia bought the BTS-2 license. Basing on BTS-2 technical data the polish as well the Czechoslovaken army devoeloped a ARV.

When it entered service in 1973 it was not only the best ARV in the whole Warsaw Pact but probably in the whole world. It is still able to carry out tasks that NATO gives ARVs of its class.
