Dassault Mystère

The Dassault Mystère was an early French jet fighter developed by Marcel Dassault's aircraft company in the years following the Second World War. It evolved from the earlier straight-wing Ouragan and introduced swept wings, marking a significant step forward in French combat aviation and helping reestablish France as a builder of front-line military jets.

Early examples were powered by British Rolls-Royce engines, reflecting the practice of the era in which proven foreign powerplants were used while domestic turbojet development matured. The aircraft was unveiled in the early 1950s and developed through several versions, with the later Mystère IV becoming the most widely produced.

The Mystère saw service with the French Air Force and was exported to several other nations. It served in combat, including in the Middle East, and laid important groundwork for Dassault's later and far more famous fighters such as the Mirage series.
