Tank origin

The German army’s interest in developing a heavily armored assault vehicle capable of demolishing well-fortified structures continued into 1943. That year, the manufacturing firm Krupp proposed a design that called for a 30.5cm L/16 siege mortar along with the running gear from a Tiger tank. The 120-ton Bär (“bear” in English) never existed beyond blueprints. However, it is said to have influenced the design of the SturmTiger.
