13 Facts About ISU-152

ISU-152 is a Soviet self-propelled gun developed and used during World War II.

Since the ISU-152's gun was mounted in a casemate, aiming it was awkward, and had to be done by repositioning the entire vehicle using the tracks.

Beginnings of the ISU-152 came on 24 January 1943, when the first prototype of the SU-152 was unveiled.

ISU-152 followed the same design as most other Soviet self-propelled guns.

ISU-152 was armed with the same gun as the SU-152, but it used the hull of the IS-1 tank instead of the KV-1S.

The ISU-152 carried 21 rounds of two piece armor-piercing and high explosive ammunition.

Later ISU-152 versions had a newer gun with a slightly longer barrel, up to over 4.

ISU-152 had different versions, with changes in the gun, the number of hatches, or the hull.

The ISU-152 was used for infantry and tank support in attacking fortified enemy positions in a direct-fire role, for artillery support on the battlefield in an indirect-fire role and for engagement against armored vehicles in a direct-fire role.

When supporting tanks, the usual tactics of the ISU-152 were to be used in the second line of the attack order, 100 to 200 metres behind the attacking tanks, which were usually IS tanks with equal mobility.

ISU-152 was sometimes used as self-propelled artillery for support on the battlefield and preparatory bombardments, though it had a medium range of fire and a slow speed of reloading.

ISU-152 can be seen, exhibited or simply located, at different museums and memorials around the world.
