A fairly balanced design with traditionally British emphasis on firepower and defense. The vehicle's main feature was its armament: a 20-pounder and the new 105 mm L7 gun were considered. To ensure the necessary rate of fire, the designers planned to mount the gun on an oscillating turret. Since the gun was mounted at a fixed elevation, it was equipped with simple mechanical devices to facilitate the work of the two loaders. Although the specified requirements were wholly attainable, the tank turned out to be too heavy and bulky. The project was terminated.
