Kharkovchanka , code name: Manufacture 404S, is a model of Antarctic off-road vehicle. Based on the AT-T tractor platform (itself based on the T-54 tank).

In 1974–1975, a second generation Kharkovchanka was designed and built for Antarctic service. The largest design difference was the movement of the cab and engine back out in front of the main massive rectangular body structure, as well as the addition of auxiliary power generation for electricity and heat when the main engine was not operating. Three second generation Karkovchankas came off the production line in the fall of 1975.
