The ISU-152K tank destroyer (whose prototype was designated the Object 241K) was an upgraded version of the ISU-152 tank destroyer developed from the IS tank during World War II. It was modernized at the Leningrad Kirov Plant between 1955 and 1958. After the second stage of modernization, the ISU-152K's operational range was increased by 1.65 times due to larger internal fuel tanks compared to the ISU-152M. Many of the parts and components of the new ISU-152K were unified with the T-10, T-54, and PT-76.
