A project for a light tank developed by Gavalov at the Gorky Automobile Plant in 1944. Several extremely unusual design solutions were used for the vehicle: a driver sat in the fighting compartment, and his observation device was installed in the hatch at the turret top. The device was synchronized with the driver's station and rotated with the seat against the turret. The project was discontinued at the development stage.
