There were no German rocket societies after the collapse of the VfR, and civilian rocket tests were forbidden by the new Nazi regime. Only military development was allowed, and to this end, a larger facility was erected at the village of Peenemünde in northern Germany on the Baltic Sea. Dornberger became the military commander at Peenemünde, with von Braun as technical director. In collaboration with the Luftwaffe, the Peenemünde group developed liquid-fuel rocket engines for aircraft and jet-assisted takeoffs. They also developed the long-range A-4 ballistic missile and the supersonic Wasserfall anti-aircraft missile.
