SG 113

The special device SG 113 was a projected German weapon system for anti-tank defense in World War II .

The anti-tank aircraft used in the first half of the war , especially the Junkers Ju 87 Stuka, turned out to be unsuitable in the second half of the war, as the Allies' increasing air superiority made them vulnerable to attacks by fighter planes . For this reason, considerations were made to use existing models, equivalent to the Allied fighter aircraft, for anti-tank defense.

One of the weapons systems examined was a recoilless gun, developed by Rheinmetall-Borsig , in caliber 75 mm with a barrel length of 1600 mm. However, this was not arranged to shoot forward in the longitudinal direction of the aircraft, but mounted in the wings pointing downwards. The advantage of this direction of fire is that armored vehicles have the least armor on the top, which means that even smaller calibers can penetrate the vehicle armor. The cannons should be triggered by an electrostatic or electromagnetic sensor ( forester probe ) when flying over the target.

A Focke-Wulf Fw 190 F-8 with two SG 113 in the wings was sent to the test as a test aircraft in September 1944 . The flight capability of the converted machine and the general effects of two cannons in the wings were also examined. At the end of 1944 the machine was released for troop trials. Any successes can no longer be determined. A well-known further development is the SG 116 .
