Source-derived summary

The Studebaker US6 (G630) was a series of 2+1⁄2-ton 6×6 and 5-ton 6×4 trucks manufactured by the Studebaker Corporation and REO Motor Car Company during World War II. The basic cargo version was designed to transport a 2+1⁄2-short-ton (5,000 lb; 2,300 kg) cargo load over any type of terrain in any weather. Most of these were exported to the Soviet Union under Lend-Lease by the US during World War II, since the competing GMC 6×6 CCKW design proved to be more suitable for Western Front conditions.

History

Design and development

In 1939–1940, the US Army Ordnance Corps was developing 2+1⁄2-short-ton (2,300 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.

More than 200,000 2+1⁄2-ton 6×6 trucks and similar 5-short-ton (4,500 kg) 6×4 versions in 13 variations were built. Studebaker was the primary manufacturer, which built 197,678 of them at its South Bend, Indiana plant, while REO produced 22,204 more at its Lansing, Michigan plant from 1944 under a sub-contract. Reo trucks are identical to Studebakers, but Reo built only 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.

Service

The US6 was manufactured primarily for export under Lend-Lease. The Soviet Union would become the largest foreign operator.

Editorial analysis

Why this record matters

The phrase “american exported military cargo vehicle” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jun 9, 2026. The linked authority identifier is Q1726473. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1939, 1940, 1941 and 1944.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
