Willys MA Army Jeep

The Willys Quad impressed the Army during the competition of 1940, but it was overweight and needed other design changes. The result of the redesign was the Willys MA, accepted by the Army to fulfill the 1,500 vehicle contract given to Willys on 14 November 1940. Contracts were also awarded at the same time for 1,500 of the Ford GP and Bantam BRC-40, intended for final field testing of all models before larger contracts would be let.

The full story of the development of the original Army Jeep of World War II is on the linked page.

There were 1,553 Willys MA jeeps built and delivered to the Army in 1941, with production beginning 5 June. Of these, fifty were built with four-wheel steering. Few remain since most of the original production were subsequently sent to Russia or England under Lend-Lease. On 23 July 1941, after much controversy and behind the scenes maneuvering by the bidders, the War Department awarded the 1/4-ton truck production contract to Willys-Overland based on their Willys MA design and their low bid of $738.74. The contract came with the stipulation that the weight and other design problems of the Willys MA be corrected, and that other improvements be made based on superior elements of the Bantam and Ford competitors. The result of those changes was the Willys MB (also built by Ford as the GPW), the standard World War II jeep used in all theaters of World War II, all over the world, by the U.S. and its allies.

Additional photos of the Willys MA are found in the Military Jeeps section of the Military Vehicle Charts.
