Panzer VII Maus

The Panzer VII Maus Heavy Tank was first proposed in 1942 and the first turretless prototype was built in 1943. A second turreted prototype was built in 1944, however, the Maus never saw action, being mechanically sabotaged by the Germans, and captured by the Russians, who eventually delivered it to the Kubinka Tank Museum. Had the Maus been built, however, it would have proven itself a formidable foe, with a proposed primary armament of 128mm gun (compared to the 88mm of the German Tiger tank), with a co-axial 75mm gun. The tank's armor reached 460mm at its thickest.

Armaments

 * 1x 128mm gun similar to the Pak 44 anti-tank gun. This weapon fired a 128mm shell at a muzzle velocity of 935 meters per second, proving itself able to pierce a little more than 200mm of armor at 1 kilometer and 148mm of armor at 2 kilometers.


 * 1x co-axial 75mm gun. I am unable to find data on the performance of the Maus' 75mm, but the 75mm on the German Panther was capable of piercing 106mm of armor at 2 kilometers and 149mm at 1 kilometer.
