The DFS 346 (Samolyot 346) was a German rocket-powered swept-wing vehicle subsequently completed and flown (with indifferent success) in the Soviet Union after World War II. It was designed by Felix Kracht at the Deutsche Forschungsanstalt für Segelflug (DFS), the "German Institute for Sailplane Flight". The prototype was still unfinished by the end of the war and was taken to the Soviet Union where it was rebuilt, tested and flown.
