Comparing: SU-122-44 vs. SU-152

Development was started in June 1944 by the Uralmash Design Bureau. The vehicle was based on the T-44 chassis and had a conventional configuration, with the front placement of the fighting compartment. In October, People's Commissariat of the Tank Industry considered the SU-122-44 project. In December the design project was ready. However, the SU-100M-2 with the rear placement of the fighting compartment was preferred.

Development of a tank destroyer on the basis of the KV-1S heavy tank began on January 4, 1943. The vehicle received the designation KV-14 (Object 236). A prototype underwent field trials at the beginning of February 1943 and entered service on February 14, 1943. In April, the KV-14 was renamed SU-152. By December 1943, 670 vehicles were manufactured. Thanks to its ability to successfully combat german Tiger I and Panther tanks, the SU-152 was dubbed "Hunter" by the troops.
