M-28 / M-29 Weasel Amphibious Vehicle
M-28 or M-29 Weasel Amphibious Vehicle
The Weasel began development in 1942, to meet a requirement by the First Special Services Force for transportation into Norway where the target was power plants supplying Germany with electricity. The vehicle specifications included:
An entirely new and innovative vehicle was needed, under wartime pressures to get it done yesterday. Studebaker Company accepted the challenge of a 180-day schedule to produce the vehicle. In less than 60 days, they had a prototype, which, after testing and improvements, was standardized as the M28 Cargo Carrier. While the mission to Norway was cancelled, the Weasel was a versatile vehicle that could be used for command, radio, ambulance, signal line laying, and light cargo. It operated effectively on difficult terrain such as snow, swamps, sand, deep mud, and lakes. It was used in Europe, the Pacific and Alaska during World War II, and by VJ Day, over 15,000 had been built. During the decades following WW II, the M29C was used in Arctic and Antarctic Operations, supporting explorers and scientists.

The M28 Weasel has two seats with its engine centered in the rear. Its tracks are lightly supported by only four pairs of road wheels. The top run of the track slants upward from the rear sprocket to the higher front drive sprocket. The electrical system is 6 volt.
The M29 Cargo Carrier (Weasel), standardized in November 1943, had four seats and moved the engine to the front right. It has tracks with a mild slant downward to the front, robustly supported by eight sets of road wheels on an improved suspension. The electrical system is upgraded to 12-volts. During production, the track width was increased from 15 to 20 inches.
The final version of the Weasel was the M29C, an fully amphibious version that added watertight cells for buoyancy and twin rudders at the stern. Over 10,600 of the M29C were produced, although some were stripped of their floatation tanks and rudders once in the field.
