SNCASE SE.580

The SNCASE SE.580 was a prototype fighter designed during World War II by the French aircraft company SNCASE (Société nationale des constructions aéronautiques du Sud-Est). Loosely based on the pre-war Dewoitine D.520, it was intended to be powered by a Hispano-Suiza 24Z piston engine. Production began on a single prototype, but the program was cancelled before it was completed.
