Air-to-Air Rockets for Aerial Combat
From the beginning of 1944 remote-controlled and spin-stabilised rockets grew in importance in aerial warfare. They were initially simply aimed by eye (Werfergranate WGr 21), but later a whole series of guided and spin-stabilised missiles was developed. Except for the R4M none was ever even partially ready
for a series run by the war’s end because of problems in obtaining materials and Allied domination of the skies over the shrinking Reich.
