Following the SU-152's performance at Kursk, the SU-152 played a very important role in destroying German fortifications during the Operation Bagration offensive, this being the vehicle's original design goal..From the second half of 1943 to the end of World War II SU-152s were used on all Soviet fronts, from Finland to the Crimea. Due to combat losses and mass production ceasing in December 1943 the number of SU-152s in the Soviet Army decreased. Eventually SU-152s were replaced by the more reliable and better-armored ISU-152, which used the same armament and ammunition in the same dual-purpose role.
