Historical Record

Provenance & Service

Developed by Rheinmetall, the Karl-Gerät was a 600 mm self-propelled siege mortar designed to demolish heavy fortifications. Six were built. They saw service at Sevastopol in 1942 — alongside Schwerer Gustav — at the Warsaw Uprising in 1944, and during the Battle of the Bulge. One example, 'Ziu', survives at Patriot Park near Moscow.
