The Panzerkampfwagen Bär was a German self-propelled gun project from the end of World War II. A prototype of this weapon has never been produced, let alone the car has never entered mass production. The Panzerkampfwagen Bär was to be a heavy assault gun, armed with a 305mm cannon with a barrel length of 16 calibers. It was supposed to be mounted in the rear part of the car in a permanent casemate - just like in the Ferdinand car (Sd. KFz.184) - without the possibility of its rotation. It was assumed that the new vehicle would be heavily armored, and the chassis and suspension were to be the same as in the Pz.Kpfw. VI Tiger II. It was planned that the length of the car would be approx. 8.2 meters, and the weight would reach approx. 120 tons. The crew was to consist of 6 people. It is debatable what engine such a heavy vehicle would be powered by - perhaps it was to be doubled engines Maybach HL230, which is the same as used in Pz.Kpfw. VI Tiger II.
