The GAZ-51 (Russian: ГАЗ-51) is a light truck manufactured by the Soviet vehicle manufacturer Gorkovsky Avtomobilny Zavod. The vehicle was designed before the Second World War and mass-produced together with the all-wheel-drive version GAZ-63 after the end of the war. Under the designation GAZ-93, a tipper was produced on the basis of the GAZ-51.
The GAZ-51 was a 4x2 2.5 ton truck while the GAZ-63 had all-wheel drive.
The ZIS-151 (Russian: ЗИС-151) was a general-purpose truck produced by the Soviet car manufacturer Automotive Factory No. 2 Zavod imeni Stalina in 1948–1958. In 1956, the factory was renamed to Zavod imeni Likhacheva, and new trucks were called ZIL-151 (ЗИЛ-151).
The ZIS-151 was the first major Soviet military all-wheel-drive truck built following World War II, replacing the imported U.S. Studebaker US6 and the earlier Soviet ZIS-6. In early 1948, the cabs were made of wood, soon replaced with a steel cab. Tens of thousands were produced, including specialized versions for hauling different types of cargo. The Soviets also found the trucks an ideal platform for BM-13 Katyusha rocket launchers.
The most famous developments of ZIS-151 were the BTR-152 armored personnel carrier and the BAV 485 amphibious vehicle. Due to de-Stalinization the ZIS-151 was renamed in 1956 to ZIL-151.
In 1958, an improved model, the ZIL-157, was introduced and replaced the ZIS-151. It differed outwardly by its grille and having single rear tires, instead of the ZIL-151's dual tires.
In 1956, the Chinese began building the ZIS-151 under license as the Jiefang CA-30 at First Automobile Works, with slightly more power and angular front fenders. The improved single tire CA-30, introduced in 1958, remained in production until 1986.
