In 1945 the Western Allies and the Soviets came upon many secret installations that were burning tons of designs for exotic weaponry on land, air, sea, and even space! The Western Allies got the Supersonic Zippermayr Pfeil (Arrow) under construction and the Lippisch DM-1 delta, while the Soviets got the DFS-346 supersonic aircraft under construction and plans for the space Saenger Silbervogel spaceplane. Other spaceplane designs were shared like the EMW A-series of manned V-2s. The US discovered a plan for a nuclear powered Nazi aircraft, the Hyperschallflugzeug by Skoda-Kauba designed for 10,000 mph (Mach 13.3) and the Soviets at Peenemunde discovered a scale model of a strange U-shaped aircraft called the Uberschallflugzeug or Uflugzeug. It was shaped like a magnet with a central fuselage was sandwiched between two V-2 rockets! The bomber had radar in the nose and provision for a single bomb to drop on London to destroy the heart of the city. The type is unknown but could have been a German nuke, FAE, liquid air bomb. or Nowak's Molecular bomb. The model was examined in the USSR but deemed impractical to build as was the Saenger Antipodal bomber! It was designed to fly at 4500 mph to target, drop its load, turn around, and then ditch in the Atlantic while the crew ejected its capsule and were to be picked up by loitering U-boats. A revenge weapon, its probable designation would have had to been V-6 as V-1 thru 5 were taken and the V-7 is still not know whether it was a Vril 7 disc craft or Miethe's V-7 unmanned aerial weapon. FYI

Note: The Henschel V-4 was an extended range ramjet cruise missile found on Misdroy that probably led to the postwar Soviet Ghost Rockets that plagued Scandanavia. The V-5 was the DFS Bombensegler (aka Hitler's Pub Dart) designed to hit London towed by a Bf 109!
