Praga V3S

The Praga V3S is an all-terrain multi-purpose truck, produced since 1953 in Czechoslovakia, it was especially designed for the armed forces and was also exported to 72 foreign countries. Praga produced the truck until 1964, after which the Bratislava company BAZ rolled out these vehicles till 1990. Around 130 thousand units were manufactured. The truck was among the best off-road cargo vehicles of its time and the Czechoslovak Army used it for more than half a century. It was the longest produced Czechoslovakian truck.

Development
For the development till prototype stage of the truck, designers were given only four months, they have been inspired mainly by the American Studebaker US6 and Russian ZiL. Due to the design of axle gearboxes (axles are positioned high above the wheels axis), the V3S has a high ground clearance, this structure provides great terrain passability, but on the other hand limits the maximum speed (60 km/h). The V3S was a durable, popular and extremely adaptable truck built in various versions and widely exported, therefore it is not difficult to see V3S based vehicles still hard at work nowadays.

It is relatively noisy, but works reliably even in extreme conditions. Climbing ability is up to 75% (without tow).
