“On 17 January 1945, all development projects were canceled by the Luftwaffe in order to concentrate all possible efforts on only two designs.”

“The operational version was intended to be fired from a ramp or converted gun mount. The project was canceled on February 6, 1945.”

“The operators used a telescopic sight and a joystick to guide the missile by radio control,”
“59 Hs 117 missiles were tested, some from beneath a Heinkel He 111; over half the trials failed.”
“Operational missiles were to be launched from a 37mm gun carriage.”
“The Hs 117H was an air-launched variant, designed to be launched from a Dornier Do 217, Junkers Ju 188, or Junkers Ju 388.”

“Among the many development problems, control of the high-speed rocket was a significant concern, leading to the development of a radio control system where the operator sat in a reclining chair so they could see the target as it passed overhead.”
“lack of a suitable proximity fuse, which was required as there was no way for the operator to visually determine when the rocket was close to a target that was directly above it. A radar-aided system was still under development and not ready for operational use.”

F-25: " F-25s had been fired. However, the test results did not meet expectations and so the development of the F-25 was still set before end of 1944."
“With the completion of the development of the F-25, the main interest in the LFA focused on the F-55. This was a remote-controlled 2-stage supersonic”
“further launches of the F-55A2, which demonstrated their unstable flight behaviour. The launch of the improved F-55A3 was aborted on 21 October 1944 because of technical problems.”
“To accelerate the development and to obtain reliable results, on 14 January 1945 it was decided to use the unmodified drive from the Henschel Hs 293”
“The F-55 would have a larger tail for greater flight stability.”
“these changes were scrapped.”
This means none of them were ever utilized in the frontlines and or were incredibly inaccurate due to user error. However, the Henschel Hs-117 Schmetterling could be added to the He-111, Do-217, Ju-188, and Ju-388.
