Photo gallery of a Dassault Etendard IV M,
The Dassault Étendard IV was a subsonic carrier-borne strike fighter aircraft, which entered service with the French Navy in 1962. It served as the basis for the more advanced Dassault-Breguet Super Étendard. During the 1970s, it had been intended to replace the Étendard IV with a navalised version of the SEPECAT Jaguar, designated as the Jaguar M, however development of the Jaguar M was cancelled and shortly replaced by the Super Étendard. The Étendard IV was progressively withdrawn during the 1980s and finally retired from service with its sole operator in 1991.
