The Voroshilovets is a heavy artillery tractor based on the T-24 tank chassis designed to tow large-calibre artillery systems. Development was carried out under the leadership of the chief designer N.G. Zubarev and his deputy D.F. Bobrov in 1935. The Voroshilovets was used by the Soviet Union and Nazi Germany after capture, beginning production from 1939 to August of 1942, where it halted production at the Stalingrad Tractor Factory. Early production started in KhPz in 1939, but production shifted to the Stalingrad Tractor Factory in 1941 after the German invasion until August 1942. 1123 tractors were built within the span of production. It first featured a VD-2 diesel engine in prototype versions, then Kharkiv V2V engine, a detuned version of the V2 engine (used in the T-34 and BT-7M) intended for use in lighter vehicles. It was used until the 1950s.
A downside of the tractor was of the fuel consumption and capacity.
