On this day, in 1958, Étendard IV M made its first flight in Melun-Villaroche with Jean-Marie Saget at the controls.
In 1955, the engineering department of aeronautics asked Dassault to redesign the Mystère XXIV (Étendard IV), proposed to the Air Force, to turn it into a ” low-altitude fighter and attack seaborne aircraft”. The seaborne Étendard IV M prototype was a low and middle altitude fighter and attack aircraft, deployable from aircraft-carriers of the Clemenceau class, and fitted with the 4400-kg thrust Snecma Atar 8 jet engine.
Its performance and external load capacity made the Étendard IV M an excellent attack aircraft, with a secondary role as an interceptor and aerial combat aircraft. Étendard IV M remained in active service in the Navy until July 1991, in a ship-borne fighter school, the Squadron 59 S of Hyères, which they had entered in October 1965. They carried out in all 180 000 hours of flight and 25 300 landings.
