The Panzerkampfwagen VII Löwe (Lion) was a design for a super-heavy tank created by Krupp for the Nazi German government during World War II. The project, initially code-named VK 7001 (K), never left the drawing board, and was dropped in late 1942 in favor of the Panzer VIII Maus. The Löwe was designed in two variants: When shown the designs, Adolf Hitler ordered the Leichter Löwe dropped and the Schwerer Löwe re-designed with a 150mm main gun, 140mm frontal armor, and a top speed of 30 km/h.
