For Sale: 6x6 Ford Truck Developed as an Amphibious Military Prototype Circa 1960

A 3.5-ton, amphibious 1960 Ford 6×6 military prototype is up for sale in a Bring a Trailer listing, designated XM434E2. Built around 1960 as part of a canceled late-1950s U.S. Army Ordnance Corps program for medium-duty trucks, it never advanced beyond the prototype stage despite reportedly involving proposals from General Motors and REO alongside Ford. The truck was designed to be air-dropped and to operate in water using a duplex-drive system sending power to the wheels or a rear propeller. It’s 20 feet long with an 126-inch wheelbase, powered by a 534-cubic-inch diesel V8 making 195 hp. The incomplete project needs tuning, has leaks, missing propeller driveshaft, and corrosion, though it has a Wisconsin title and VIN for registration.
