Who canceled the project for the Landkreuzer P. 1000 Ratte, which would have surpassed the Panzer VIII Maus as being the heaviest fully enclosed armoured fighting vehicle ever built?
Panzer VIII Maus Panzerkampfwagen VIII Maus ("Mouse") was a German World War II super-heavy tank completed in late 1944. It is the heaviest fully enclosed armoured fighting vehicle ever built. Five were ordered, but only two hulls and one turret were completed before the testing grounds were captured by the advancing Soviet forces.
Gepanzerter Mannschaftstransportwagen 'Kätzchen' The Gepanzerter Mannschaftstransportwagen Kätzchen ("Gep. MTW Kätzchen") (German for kitten) was a German armoured personnel carrier of late World War II. Auto-Union delivered two prototypes during 1944-45. The hull's shape was similar to the hull of the "Panzerkampfwagen" Tiger II, but much smaller. The vehicle had front wheel drive with five or six overlapping steel road wheels, possibly resembling the never-built E-25 "replacement tank"'s suspension system in appearance. Power was provided by a Maybach HL50 engine.
