Vehicle description

Wargaming Tankopedia

Development of the T95 series started in 1953. In June of the same year, H.L. Yoh Company Inc. presented seven blueprints, including the M-IV-Y project. It was supposed to be a 47-ton medium tank with a standard configuration for American tank building: a cast hull and turret, a 105 mm gun, and four crew members. The most outstanding feature of the project was its oscillating turret. It had a stationary lower frontal part that protected the oscillating segment from damage and jamming. However, further M-IV-Y development was discontinued, and it existed only in blueprints.
