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 advancing Soviet military forces.
Centurion (tank)
"The Atomic Tank" is now located at Robertson Barracks in Palmerston, Northern Territory. Although other tanks were subjected to nuclear tests, 169041 is the only one known to have withstood a blast and to go on for another 23 years of service, including 15 months on operational deployment in a war zone.
The designations follows the pattern of main gun calibre in centimetres followed by the service order number. Hence the strv 81 is read as the first tank with an 8 cm gun, while the strv 101 is the first tank with a 10 cm gun that was accepted into service.
