Development of this superheavy tank was started after the Battles of Khalkhyn Gol in 1939. The vehicle was designed as a maneuverable fire unit that was unprecedented in scale—its hull alone weighted 100 tons. Only one prototype was built, without a turret and made of construction steel. Trials were discontinued due to the unreliable engine, and at the end of 1944, the prototype was scrapped. The 15 cm howitzer was to be mounted on the tank after assembly.
