Can be built as either the V1 or V2 version.

The first, turretless prototype (V1) was assembled by Alkett in December 1943. Tests started the same month, with a mockup turret fitted of the same weight as the real turret. In June 1944 the production turret, with armament, was used for tests.

In March 1944 the second prototype, the V2, was delivered. It differed in many details from the V1 prototype. In mid-1944, the V2 prototype was fitted with a power plant and the first produced Maus turret. This turret was fitted with a 128 mm KwK 44 L/55 gun, a coaxial 75 mm KwK 44 L/36.5 gun and a coaxial 7.92 mm MG 34. The V1 prototype was supposed to be fitted with the second produced turret, but this never happened.
