Dewoitine D.560

The Dewoitine D.560 was a prototype French single-seat fighter developed by Dewoitine as an alternate to the Dewoitine D.500.^[1] The design failed to better the performance and only one aircraft was built.^[1]

To provide an alternate design in the competition to supply the French Air Force with a successor to the Nieuport 62.^[1] Rather than the low-wing monoplane design of the D.500 the D.560 had a shoulder-mounted gull wing.^[1] During test flying the D.560 was found to be slower than the D.500 and had stability problems.^[1] The aircraft was rebuilt with a parasol wing and redesignated the D.570.^[1] Performance was even worse than the gull wing design, and following a crash of the prototype development was abandoned.^[1]
