Haunebu III was the last of the Haunebu flying saucer series, constructed on Earth. Many of them were sent from Antarctica to the Moon, where their crews built the Schwarze Sonne base.

At the end of World War II, Haunebu-III was developed with a diameter of about 70 meters. The prototype made 19 flights during which the properties were tested. It could accommodate in its interior up to 32 people and develop a speed of Mach 10 (about 40000 km / h). The ship's engines consisted of electrogravity generators.
