Re: FV-QR (Preppy)
Panzer VIII Maus
The Panzerkampfwagen VIII Maus (Sd.Kfz 205) was a German super-heavy tank design, and the heaviest tank to reach the complete working prototype stage in World War II. The basic design known as the VK7001/Porsche Type 205 was suggested by Ferdinand Porsche to Adolf Hitler in June 1942, who subsequently approved it. The design up to then had been the culmination of work done by Porsche who had won the contract for the heavy tank that March.
The tank's hull was 10.1 metres (33 ft 2 in) long, 3.67 metres (12 ft 0 in) wide and 3.66 metres (12.0 ft) tall. Weighing about 180 tonnes (180 LT; 200 ST), the Maus's main armament was a 128-millimetre (5.0 in) cannon with a coaxial 75-millimetre (3.0 in) gun and steel armour ranging from 60–240 millimetres (2.4–9.4 in) in thickness. A total of nine were in various stages of completion and two were completed when the war ended.
T-28 Super Heavy "Tank" - actually a self propelled gun.
Schwerer Gustav
80cm rail mount canon, two were built and fielded by Krupp.
