This tank project had two key features—a new fighting compartment configuration and a dual-loop caterpillar propulsion system, which, according to the developers, could boost firepower and mobility. A divider split the fighting compartment into separate crew and gun compartments. The automatic loading system consisted of a main three-shot loading system and an auxiliary mechanized rack. The design made it possible to load the gun and replenish the main rack without setting the gun to a fixed loading angle, significantly increasing the rate of fire and improving the crew's comfort. The track loop was divided into two parts, enabling the vehicle to stay mobile even if it hit a mine. However, the dual-loop propulsion system made the chassis heavier and made the tank more difficult to drive and steer. The project went no further than blueprints.
