76 mm Fla-Sfl 29-K
The 76-mm-Fla-Sfl 29-K ( Russian 76-мм зенитная самоходная установка 29-К ) is an anti - aircraft self-propelled gun developed in the 1930s in what was then the Soviet Union . The vehicle was manufactured in small numbers and used in the Red Army . The GAU index of the weapon system was 52-P-361-A (52-П-361-А).
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. Attempts to develop a heavy flak tank had not led to satisfactory results with either the 76 mm Fla-Sfl SU-6 or the 76-mm Fla-Sfl SU-8 .
The 29-K was developed in the design office of Plant No. 8 from 1934. A 76 mm M1931 anti-aircraft gun was placed on the chassis of the JaG-10 truck . 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. Plant No. 8 in Kaliningrad near Moscow (today Koroljow) was selected for the series production of the anti-aircraft gun. In 1935, the plant was commissioned to manufacture twenty cannons without a sub-mount, which were intended for assembly on the JaG-10 truck. The plant was able to fulfill the order, but only twelve of the trucks had arrived by the end of 1935. The twenty self-propelled guns were not finally completed until August 1936. In that month, testing began on the polygon in Rzhevsk (Ржевский полигон) near Leningrad .
The chassis of the truck was taken over unchanged. The gun was mounted on a low base mount on the loading area. The firing line of the weapon was 85 mm lower than that of the rifled variant. Four protective shields were installed to protect the crew. The shields were folded down for the fire fight. They then formed the platform for operating the cannon. Two ammunition boxes for twenty-four grenades each were mounted on the front part of the loading area. The crew of a total of four soldiers also found space on the loading area.
The self-propelled gun generally only led the fire from a standing position. Due to the towering driver's cab, the elevation range at an angle of ± 30 ° to the longitudinal axis of the vehicle was limited to a range of + 10 ° to + 85 °. For self-defense the Sfl could also lead the fire from the movement. The elevation range was limited to ± 3 °.
