Studebaker US6Produciton year 1945
The Studebaker US6 (G630) was a series of 2½-ton 6x6 and 5-ton 6x4 trucks manufactured by the Studebaker Corporation and REO Motor Car Company during World War II. The basic cargo version was designed to transport a 5,000 lb (2,300 kg) cargo load over all types of terrain in all kinds of weather. Most of these were exported to the Soviet Union under Lend-Lease by the USA during World War II.
In 1939-1940 the US Army Ordnance Corps was developing 2 1⁄2-ton (2,238 kg) tactical 6×6 trucks that could operate off-road in all weather. Studebaker, Yellow Coach (a GM company) and International Harvester all submitted designs that were accepted and went into production in 1941.
A total of 219,882 2 1⁄2-ton (2,268 kg) 6x6 trucks and similar 5-ton (4,536 kg) 6x4 versions in thirteen variations were built. Studebaker was the primary manufacturer, which built 197,678 of them at their South Bend IN plant, while REO produced 22,204 more at their Chicago IL plant from 1944 under a sub-contract.
REO trucks are identical to Studebakers, but REO only built cargo-model trucks with the long wheelbase and without the front-mounted winch, more specifically referred to as the US6 U9. All production by both manufacturers ended in 1945.
The Russian Army particularly enjoyed their Studebaker stocks as they found that the Hercules engine could run on just about any type of gasoline at hand. Standard gross weight limits were regularly exceeded out of sheer necessity and Soviet personnel grew so fond of the American product that they referred to them simply as “Studers”. Eventually, various improvised configurations (never envisioned by its American designers) were implemented.
Most of the Studebaker trucks were built with a closed hardtop cab based on the civilian Studebaker M-series cab design – as the harsh weather in the Soviet Union essentially required it. The US6 and the GMC CCKW series trucks shared a similar external appearance to one another though closer examination revealed the fuel tank in the US6 set to the driver’s side while the CCKW fit this along the passenger side. The US6 cab also featured “swing-out” forward windscreens with roof-mounted windshield wipers.
