The project gave the DFS the opportunity to investigate two additional areas that it was interested in - the effects of wing sweep on sailplane design, and supersonic flight. The DFS 228 was designed by Felix Kracht and a first prototype was completed in March 1944 and was undergoing gliding tests by August, carried aloft piggyback on a Dornier Do 217. The aircraft was of conventional sailplane design, with long, slender wings, and intended to land on a skid mounted on its belly. The nose of the aircraft could be separated in an emergency, and formed a self-contained, pressurised escape capsule for the pilot. Because of problems with the cabin pressurisation system, the second prototype accommodated the pilot in a prone position. Some forty flights were made with the prototypes, and installation of a Walter HWK 109-509 rocket was to have taken place in February 1945, but the project fell by the wayside as the war situation became more desperate. The second prototype was destroyed in an air raid in May 1945, and the first prototype was captured by US troops in June. In 1946, it was sent to the United Kingdom for study, where it was apparently scrapped in 1947, although its exact fate is unknown.
