Henschel Hs 117


The Henschel Hs 117 Schmetterling was a radio-guided German surface-to-air missile project developed during World War II. There was also an air-to-air version, the Hs 117H.
The operators used a telescopic sight and a joystick to guide the missile by radio control, which was detonated by acoustic and photoelectric proximity fuses, at.

Development

In 1941, Professor Herbert A. Wagner invented the Schmetterling missile and submitted it to the Reich Air Ministry, who rejected the design because there was no need for more anti-aircraft weaponry.
However, by 1943 the large-scale bombing of Germany caused the RLM to change its mind, and Henschel was given a contract to develop and manufacture it. The team was led by Professor Wagner, and it produced a weapon somewhat resembling a bottlenose dolphin with swept wings and cruciform tail.
In May 1944, 59 Hs 117 missiles were tested, some from beneath a Heinkel He 111; over half the trials failed. Mass production was ordered in December 1944, with deployment to start in March 1945. Operational missiles were to be launched from a 37mm gun carriage.
In January 1945, a prototype for mass production was completed, and production of 3,000 missiles a month was anticipated, but on 6 February, SS-Obergruppenführer Hans Kammler cancelled the project.

Variants

The Hs 117H was an air-launched variant, designed to be launched from a Dornier Do 217, Junkers Ju 188, or Junkers Ju 388. This version was designed to attack enemy aircraft up to above the launching aircraft.
