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.

Yet larger still was the 71 meter diameter lone prototype that was constructed before the close of the war. It was crewed by 32 men and could achieve speeds of 7,000 to 40,000 km/h. It had a triple Victalen hull and it's said to have had a flight endurance of 7 to 8 weeks. Allegedly, the craft made 19 test flights.
