More interesting information on the R4M rocket in WWII.
"The best success was finally achieved with air-to-air missiles that had been specifically developed for attacking aircraft. After I had been almost exclusively employed against four-engine bombers from 1943 until the end of 1944, I was able to activate the first jet fighter wing equipped with the Messerschmitt 262 jet fighter, and we began to arm our aircraft with air-to-air missiles, designated R4M with a caliber of 50 millimeters. Underneath each wing, we mounted 24 of these missiles and fired them in a salvo of 48 missiles from a distance of 1,000 meters. The results were exceptionally good, for when firing at close enemy formations one kill was usually certain. However, these air-to-air missiles were not used by conventional aircraft, but only by jet fighters." Lieutenant General Johannes "Macky" Steinhoff
Inspector General, German Air Force
