The SU-152 was a Soviet self-propelled heavy howitzer used during World War II.
About this creation
The SU-152 mounted a 152 mm gun-howitzer on the chassis of a KV-1 heavy tank. Because of its adopted role of as an impromptu heavy tank destroyer, capable of knocking out the heaviest German armoured vehicles— Tiger and Panther tanks, and Elefant tank destroyers—it was nicknamed Zveroboy, "beast killer".
The Stalingrad counteroffensive, Operation Uranus, exposed the Red Army's urgent need for mobile heavy guns. Primary targets for these guns were German fortifications in and around Stalingrad. At the time Soviet front-line ground units did not possess sufficient firepower to deal with pillboxes and other fortifications. A heavy assault gun was needed.
The entire project to develop a new assault gun was designated "KV-14" and assembly of the first prototype (called "Object 236") began on December 31, 1942. It was completed after 25 days. After a number of successful plant tests the more stringent state tests began. "Object 236" succeeded again. On February 14, 1943 the State Defense Committee accepted it for Red Army service and immediately launched it into mass production. The designation of the series of self-propelled guns was changed from KV-14 to SU-152.
Although designed with no consideration for the anti-tank role, the SU-152 proved to have surprisingly good anti-tank capabilities due to the ML-20S's extremely heavy HE projectiles. Standard doctrine for purpose-built AT guns of the period universally relied on small, dense solid projectiles propelled to high velocities, optimized for punching through armor. Since the SU-152, like all SU-series self-propelled guns was not designed with tank killing in mind, no AP projectiles were issued to crews and no initial tests against armor were conducted. However, tests performed on captured Tiger tanks in early 1943 showed that the SU-152 was able to destroy them at any range with a fair degree of reliability (the only vehicle then in Russian service capable of doing so) by simply blowing the turret off the vehicle through sheer blast effect. This fortuitous discovery spurred massive SU-152 production and the formation of self-propelled artillery units, which then functioned as ersatz heavy tank destroyer battalions
Since it was intended as a self-propelled artillery piece rather than a true tank destroyer, the SU-152 was generally issued with standard HE rounds rather than armor-piercing projectiles. The 152mm HE round produced a massive blast that did not rely on velocity for its effectiveness, making them effective against any German tank, including the Tiger and Elefant (although with a somewhat decreased level of kill reliability over penetrating projectiles). It was renowned for its ability to rip the turret completely off a Tiger tank (at any range) by sheer blast effect alone, and numerous German AFVs were claimed as destroyed or damaged by SU-152 fire during the Battle of Kursk.

It is very good, although it looks to tall and too short... probably due to playability, because the figures need to fit. But IRL tankers were usually sitting in the tanks, and the space in there was pretty cramped. Still an excellent model.
Another very nice model. Excellent details. Playability is always a top priority for my builds as well because of my little boy. Like the way you handled the corners around the upper hull and "turret" area. Well done.
