The IS-1 (losif Stalin 1) was a Soviet heavy breakthrough tank from WWII, developed from the KV series to counter German Tigers and Panthers, featuring thick sloped armor and an 85mm D-5T gun, but was quickly replaced by the more powerful IS-2 due to its gun's inadequacy, with only about 107-200 produced before production ended in early 1944. It served briefly with Guards Heavy Tank Regiments in early 1944, primarily in Ukraine and Slovakia, before being superseded by its formidable 122mm-armed successor, the IS-2.
A response to formidable German tanks like the Tiger and Panther, evolving from the KV-13 program and serving as an interim step before the IS-2. Initially known as the IS-85 during trials, it became the IS-1 upon entering limited production in late 1943. Featured an 85mm D-5T main gun, which proved insufficient against heavy German tanks at range, and three DT machine guns. Known for its well-sloped, thick cast armor, offering good protection, though its lower front plate was a weakness.
Produced in small numbers (around 107-200) from late 1943 to early 1944 at the Chelyabinsk Kirov Plant, as the IS-2 with its powerful 122mm gun offered superior performance. Saw limited service with Guards Heavy Tank Regiments in early 1944 in Ukraine and later in Slovakia. An important transitional heavy tank, paving the way for the iconic IS-2, a significant breakthrough vehicle in the final stages of World War II.
