This weapon was manufactured by Rheinmetal-Borsig and was essentially a longer barrel and improved version over the older 3.7 cm/83 SK C/30 and had a much higher rate of fire. Recoil operated, air cooled and used five-round ammunition strips. These were the first German light anti-aircraft guns to have shields, a surprising shortcoming of earlier weapons.
The design of this gun emphasized ease of manufacturing. Constructed of a monobloc barrel connected to the breech ring by a bayonet joint to allow easy replacement. Used a vertical sliding breech block, hydraulic brake and spring recuperator.
Near the end of World War II twin guns were mounted on some submarines.
