The Fieseler Fi 103R, code-named Reichenberg, was a late-World War II German manned version of the V-1 flying bomb (more correctly known as the Fieseler Fi 103) produced for attacks in which the pilot was likely to be killed (as with the Japanese Ohka rocket-powered suicide anti-ship missile) or at best to parachute down at the attack site, which were to be carried out by the "Leonidas Squadron", V. Gruppe of the Luftwaffe's Kampfgeschwader 200.
