On this day, in 1956, Étendard IV made its first flight in Mérignac with Georges Brian at the controls.
The Mystère XXIV, which became the Etendard IV, was the object of a contract awarded to the Mérignac Avions Marcel Dassault corporation on Novembre 1954. A Marine version was envisaged from the outset, taking account of the adaptations required for maritime operation (folding wings, deck landing hooks, reinforced fuselage and landing structures and the accompanying navigation and radar instruments).
Flight tests confirmed the aircraft’s qualities for ground attack as well as low altitude interception missions, which aroused the interest of the Air Force and Navy. January 18, 1958, saw Pierre Galland on his 241st flight breaking the world record for speed on a 1000 kilometer stretch, flying at an average of 1020 km/h.
