Originally designated as the IS-8, this tank was a warmed over version of the IS-3 design. A heavier turret was added and a stamped belly plate in a shallow V shape. Two major revisions were made to the IS-8 before production began in 1953 as the T-10. Although equipped with a vertical gun stabilizer, the tank could not engage targets on the move. In 1957 the T-10M was introduced with a new engine, V-12 SB and a new gun, 122mm M62T2 with a distinctive multi-baffle muzzle brake. However, rate of fire was only 2-3 rounds/min. It was the standard heavy tank of the Soviets in the 1950s and 1960s. Slow and short range, they were never popular with the Commanders. All were removed from service in the late 1970s and were scrapped in 1993. Nearly all are gone. A total of 8,000 were produced.
