T18 Boarhound
The T18 Boarhound was an American heavy armoured car produced in small numbers for the British Army during the Second World War.
History
In July 1941 the US Army Ordnance Corps issued specifications for a heavy armored car (along with another specification for a medium armored car, which resulted in the T17 Armored Car) to be built for supply to the British. The prototype was developed in 1942 by the Yellow Coach Company. It was large 8x8 (eight wheels, all driven; called an "eight-by-eight") vehicle with four front wheels used for steering. Thick armor brought the weight to 26 tons, about the weight of contemporary medium tanks. Initial armament consisted of a 37 mm gun M6 in a turret with a coaxial .30 inch machine gun and another .30 inch MG in the bow mount. By then it was clear that the anti-tank performance of the 37 mm gun was insufficient and the production version, the T18E2, which was named Boarhound by the British received the 57 mm gun M1, the US-manufactured variant of the British QF 6 pounder.
