Description
Originally developed as a ship anti-aircraft gun. At the end of 1937, its land version was adopted. It was used to protect cities, enterprises and bases from air raids, in the field troops the air defense was not actually used due to the rather large mass in the stowed position - 14,600 kg.
The gun was mounted on railway platforms, stationary positions and on conventional carriages. The gun carriage had a cross-shaped arrangement of the beds - this made it possible to conduct circular shelling with an elevation angle of up to 85 Β°. To aim the gun at the target, DC motors were used . A semi-automatic wedge bolt with an electric release was installed on the gun, which made it possible to produce 12-15 rounds per minute.
In 1940, the Flak 39 guns began to enter the troops, differing from the Flak 38 in the design of the gun carriage and in that AC motors were installed, rather than direct. The armor penetration of the gun at a distance of 100 meters was 190 mm, and at 1,500 meters - 138 mm. The initial velocity of the fragmentation shell weighing 15.1 kg was 880 m / s, armor-piercing mass of 15.6 kg - 860 m / s.
