autumn of 1942 at the Chelyabinsk Kirov Plant designers headed by LS Troyanov created on the basis of the heavy tank KB-1c self-propelled SU-152 (CV-14), designed for firing at troop concentrations, long-term and strong points armored vehicles. The fully armored cabin they put on the machine-gun howitzer ML-20 with a barrel length of 26.8 caliber and piston gate. Gun had horizontal angles pointing at 12 ° to the right and to the left, reducing the angle of -5 ° and elevation +18 °. In ammunition, which consisted of rounds of separate loading, there were 48.8-pound armor-piercing and 43.5-pound high-explosive shells. Their initial rates were respectively 600 and 655 m / s, and the rate reached 2.4 shots per minute.
Baptism of fire self-propelled SU-152 received on the Kursk Bulge. Their appearance on the battlefield was for German tankers complete surprise. These self-propelled perfectly proved themselves in combat with German Tigers, Panthers and Elephanta. Their armor-piercing shells pierced the armor of enemy vehicles, tore off their towers. During that war veterans lovingly called self-propelled heavy hypericum. The experience gained in the design of the first Soviet heavy self-propelled guns, was subsequently used to create such weapon systems based on heavy tanks IP.
Total in 1943-1944 were manufactured 620 SU-152.
