The aircraft was designed by Arthur Sack, a farm owner and amateur engineer from Machern, near Leipzig. In his attempts to create a circular-winged aircraft he built five model aircraft, each with little success. He entered his fifth model, with a 1.25 meter diameter wing and 1.5 horsepower engine, in a 1939 competition for remotely controlled models with combustion engines. The models were to take off and land at the same point. None of the entries managed to do so. Sack's model was unable to take off from the ground but flew when released by hand.
At the end of 1940 Sack started design of the AS-6, a full-sized, manned aircraft and successor to the earlier models. Its wing diameter was four times larger than the last model. He built it privately in a shed at his farm, using a wood construction. In 1944 the AS-6 prototype was finished and its design documents provisionally approved. Arthur Sack enlisted the help of the chief test pilot of ATG, a Leipzig firm that assembled Junkers bomber aircraft, to test the aircraft. Approximately a dozen tests revealed multiple failings, especially in the undercarriage, and managed little more than a hop off the ground. The tests continued at an airbase in Brandis by a pilot in a Messerschmidt Me 163 unit based there. As the AS-6 did not appear on an inventory of seized items when US forces captured the airbase it is assumed that the plane was destroyed to prevent capture.
