Karl 50cm seige mortar

Karl-Gerät" (040/041) (German literally "Karl-device"), was a World War II German self-propelled siege mortar designed and built by Rheinmetall. Its munition was a 50 cm diameter, 2,170 kg shell, and the range was just over 10 km. Each gun had to be accompanied by a crane, a two-piece heavy transport set of railcars, and several modified tanks to carry shells. Designer M Bergman
