Since 1935 the Thule Society had been scouting for a remote, inconspicuous, underdeveloped testing ground their craft. Thule found a location in Northwest Germany that was known as or possibly designated as Hauneburg. At the establishment of this testing ground and facilities, the SS E-IV unit simply referred to them as the “H-Gerat” (Hauneburg Device). For wartime security reasons the name was shortened to Haunebu. In 1939 it was briefly designated as RFZ-5 along with Vril‘s machines, once the Hauneburg site was abandoned in favour of the more suitable Vril Arado Brandenburg aircraft aircraft testing grounds.

The Dornier STRAtospharen Flugzeug/Stratospheric Aircraft or Haunebu II, was tested in 1944. Two prototypes were built. These massive machines, several stories tall, were crewed by 20 men. They were also capable of hypersonic speed beyond 21,000 km/h.
