M-III-Y

USAUSA·Heavy TankHeavy Tank·HT universal

In June 1953, H.L. Yoh Company Inc. presented seven blueprints of a new tank and proposed designs for several of its components. It was planned to use the AOSI-1195-5 8-cylinder engine. The M-III-Y project included a turret with a small frontal projection, a gun mantlet of original design, suspension with horizontal shock absorbers, and an additional track inside the main one that allowed the vehicle to maintain its maneuverability if the main track was destroyed. The project was suspended. No prototypes were built.
