A Jaguar M prototype flew in November 1969. This had a strengthened airframe, an arrestor hook and different undercarriage: twin nosewheel and single mainwheels. After testing in France it went to [[RAF Thurleigh|RAE at Thurleigh]] for carrier landing trials from their land based catapult, after which, in July 1970, it underwent a series of shipboard trials from the French carrier ''[[French aircraft carrier Clemenceau (R98)|Clemenceau]]''. From these trials there were doubts about the throttle response in case of an aborted landing. The shipboard testing also revealed problems with the aircraft's handling when flying on one engine, although planned engine improvements were to have rectified these problems.<ref name="WAPJ11 p77"/> The "M" was considered a suitable replacement for the Etendard IV but the ''Aeronavale'' would only be able to afford 60 instead of 100 aircraft.<ref>Bowman 2007, p. 23-27.</ref>

In 1971, Dassault proposed the Super Étendard, claiming that it was a simpler and cheaper development of the existing Étendard IV, and in 1973, the French Navy ordered it instead of the Jaguar. However, rising costs meant that only 71 of the planned 100 Super Étendards were purchased.<ref name="WAPJ11 p77"/> The M was cancelled by the French government in 1973.<ref>Bowman 2007, p. 26.</ref>
