"ISU-122/152 Tank Destroyers" Topic

"Developed on the basis of the IS tank. The ISU-152 was conceived as a replacement for the SU-152, which was based on the KV-1s chassis. A total of 4,635 vehicles were built from November 1943 through June 1945. The ISU-152 is well-known for its 152mm BL-10 gun. To the average observer the SU-152 and ISU- 152 were visually identical, but the ISU-152 mounted a more modern howitzer known as the ML-20S (with 20 rounds), technically a gun-howitzer and a very powerful weapon, especially at the assault ranges favoured by Red Army tactics. The weapon was protected by an armoured box made up from sloping plates of thick armour, with hand rails around the edge of the roof for use by ‘tank descent' infantry who used the vehicles to carry them into action.

The success of the SU-152, coupled with the development of the IS (losef Stalin) heavy tank hull, led the NKTP to order design teams at Chelyabinsk, in cooperation the Mechanized Artillery Bureau (BAS) and General F. Petrov, to design two new heavy assault guns based on the IS-2 tank's hull and chassis. The initial vehicle, designated Object 241, or ISU- 249, was similar to the SU-152, except for a higher superstructure and more rectangular with less sloped side armour…"
