The Dassault Étendard VI was a French prototype fighter aircraft initially developed as part of a NATO competition to find a standard fighter to serve amongst member air forces. Dassault took advantage of the fact that the French Air Force had issued a requirement around the same time for a new fighter-bomber and developed aircraft in parallel as variations of the same design concept for the two prospective customers. A further development of the Étendard concept, the Étendard IV was successfully developed for French Navy service.
