SU-8 (flak tank)
The 76-mm Fla-Sfl SU-8 ( Russian: 76-мм зенитная самоходная установка СУ-8 ) is an anti-aircraft tank developed in the 1930s in what was then the Soviet Union . After a prototype was built in 1935, development was stopped. There was no series production or introduction to the Red Army .
development
In the 1920s, the Red Army developed the concept of deep operation . The breakthrough through the enemy defense was then to be made by mobile, mechanized corps with tanks and airplanes. This led to the formation of tank and mechanized infantry units. For the implementation of the concept, however, mobile and protected support weapons were also necessary. Consequently, from the beginning of the 1930s, increased efforts were made in the Soviet Union to create self-propelled guns for anti-aircraft and artillery weapons.
The SU-8 was developed from 1932 at the Artillery Academy under the direction of Professor Christow (Хлыстов), according to other information in the design office of Plant No. 185. A 76 mm Flak M1931 was combined with the chassis of the T-28 tank . With the cannon originally developed by the German company Rheinmetall , the Red Army had a modern, powerful anti-aircraft cannon produced in large numbers for the first time. The cannon was placed on a base mount on the front part of the tank instead of the turret. The controls were protected at the front and the sides by hinged drop sides. The side walls were folded down for the fire fight. They then formed the platform for operating the cannon. In order to relieve the springs of the chassis, which minimize the effects of vibrations in the chassis on the accuracy of the weapon, the vehicle was supported on fold-out support plates. In an emergency, however, the fire could be opened without support. A combat set of 108 grenades was carried in or on the vehicle.
After the construction of the only prototype, work practically came to a standstill in 1935. In 1939, work on the anti-aircraft tank was resumed because other, similar projects could not be carried out successfully. That year the focus was on developing heavy support weapons on the chassis of the T-28. A 152 mm howitzer, a 203 mm mortar and a 76 mm anti-aircraft gun were to be developed on this chassis. In contrast to the original approach, this time the weapon was placed on the rear of the vehicle. However, none of these three projects was approved, and the development of the anti-aircraft tank was finally stopped.
