German Aircraft Weapons - Jagerfaust

Systems similar to the original Schräge Musik, such as the Sondergerät 500 or Jägerfaust, were tested on day fighters as well as a variety of other airframes, including the experimental Grosszerstörer (heavy destroyer). The SG 500 Jagdfaust was an experimental airborne anti-bomber recoilless rifle. The weapon featured a simple form of automated trigger in which an optical photocell detected the dark silhouette of a bomber triggered  firing of the 50 mm projectiles vertically into the lower sides of bombers. The pilot's only task was passing underneath the targeted bomber. The Jägerfaust was tested on the Fw 190, and was destined for installation in the Me 163B and the Me 262B. The definitive night fighter version of the Messerschmitt Me 262, the Me 262B-2, was also designed to carry such an installation, but the system did not work successfully, and it was not used operationally. Trials with the Komet, however, showed very promising results with six operational aircraft modified. On 10 April 1945, a Halifax bomber was shot down by Fritz Kelb flying a Jägerfaust-equipped Me 163B operating from Brandis, Germany. It is also reported that the weapon system is credited with the kill of an Allied B-17 Flying Fortress.

A 5 cm shell was mounted in a launch tube held in place by a pair of thin pins. Five such tubes were mounted vertically (to fire upward) in each wing root.
