A superheavy 120-ton tank project developed in September–December 1942. The vehicle was supposed to have the turret from the Pz.Kpfw. Maus, while the transmission compartment, cooling system, and some other modules were to be adopted from the VK 45.02 (H). The tank was designated the Tiger-Maus. The project was canceled, but later continued during the development of the E 100.
