First Launch: 1945-01-24. Last Launch: 1945-01-24. Number: 1 . Longitude: 13.82 deg. Latitude: 54.16 deg.
The first successful launch, this reached 80 km altitude and 1200 m/s. It then flew stably in supersonic flight using its 13.5 sq. m. wing. The automatic guidance system was designed to keep the missile on course in both supersonic and subsonic flight regimes. However the wing broke off shortly after the beginning of the glide. This concluded work on the A4b/A9; the increasingly chaotic situation in Germany prevented further flight tests.
