ISU-122 (Obyekt-122)

The ISU-122 (acronym of Istrebitelnaja Samokhodnaya Ustanovka-122) was a Soviet assault gun used during World War II, mostly in the anti-tank role.

A prototype of the ISU-122 (Russian: ИСУ-122) heavy self-propelled gun was built at the Chelyabinsk Tractor Plant, in December 1943. The design shared the chassis of the ISU-152 self-propelled gun and differed only in armament, having an A-19 122-mm gun as its main weapon instead of the ISU-152’s ML-20 gun-howitzer.
