GAZ-60

The GAZ-60 was a Soviet half-track truck built by the Gorky Automobile Plant (GAZ) from 1938. It took the chassis, cab and front axle of the GAZ-AA, the licence-built Ford AA 1.5-tonne truck known as the Polutorka, and replaced the rear axle with a Kegresse-style rubber track bogie, an arrangement first worked out by the NATI institute as the NATI-V3 prototype and tested on late GAZ-AA trucks in 1937. The track system roughly doubled the kerb weight while the 50 horsepower GAZ-M four-cylinder petrol engine stayed unchanged, so top speed fell to about 35 km/h and fuel use rose sharply. About 900 were built in 1939 and 1940, and the Winter War with Finland showed them to be underpowered and prone to track breakdowns. The type was dropped, and the Soviet half-track effort moved on to the ZiS-22 and later types.
