The Russian SU-152 Assault Gun was a rushed development in the early part of 1943 and completed in just 25 days resulting in the KV-14 prototype by the Russin Chelyabinsk Construction Group.
The 152mm howitzer-gun, M1937 (ML-20) was mounted in and operated in a fully enclosed superstructure mounted on a KV-1S tank chassis.
The Russian ML-20 was a towed artillery gun that entered production in 1937. The exact model for the SU-152 was the ML-20S following some modifications to fit the gun in the vehicle, but retained the same muzzle velocity and destructive capabilities of its towed counter-part.
Designed to provide both direct and indirect firepower support for Russian Infantry against fortifications and anti-personnel, its HE rounds were also able to provide an anti-tank capability. They would simply tear the most modern of German tanks apart due to the high energy generated from such a large calibre round.
Production began on the 1st of March 1943.704 were built when production swapped to the ISU-152 in the winter of 1943.
It made its debut to the battlefield during Battle of Kursk and earnt the nickname “Zveroboy” meaning animal hunter.
