In 1984 Germany planned to develop a new MBT called Panzerkampfwagen 2000 (PzKW 2000). In 1988 the requirements for this tank were published, it was designed not as a conventional tank, it should incorporate advanced digital technologies and a new 140 mm gun.[31] For reaching a higher level of armour protection by having the same weight limit as the Leopard 2, the crew of the PzKW 2000 was reduced to only two men, who were located within the hull.[31]
