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/Nazi Germany. It is also known as the RaBo (Raketenbomber – "rocket bomber"). It was one of a number of designs considered for the Amerika Bomber mission, which started out in the spring of 1942, being focused solely on trans-Atlantic-range piston-engined strategic bombers, like the Messerschmitt Me 264 and Junkers Ju 390, the only two airframe types 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.

Activation groups: (1) open the bomb bay. (2) activate the neutron bomb. (3) release the bomb parachute and bomb flare. (7) release the brake parachutes.
