Development history

Vickers built a single A1E1 in 1926 as a command-and-breakthrough tank: a 47 mm main turret over four independent machine gun turrets, with an intercom for the eight-man crew. Cost and shifting doctrine killed any production order, but the layout was studied closely abroad and is visible in the Soviet T-35, the German Neubaufahrzeug and the British Medium Mark III. The vehicle survives at Bovington.
