Silbervogel

Silbervogel (German for "silver bird") was a design for a liquid-propellant rocket-powered sub-orbital bomber produced by Eugen Sänger and Irene Bredt in the late 1930s for The Third Reich. It is also known as the RaBo (Raketenbomber – "rocket bomber"). It was one of a number of designs considered for the Amerikabomber project, which started in the spring of 1942, being focused solely on trans-Atlantic-range piston-engined strategic bombers such as the Messerschmitt Me 264 and the Junkers Ju 390, the only two airframe types which were actually built and flown for the competition. When Walter Dornberger attempted to create interest in military spaceplanes in the United States after World War II he chose the more diplomatic term antipodal bomber.
