VIDEO: Carrier trials of SEPECAT Jaguar M on FS Clemenceau (July 1970)

Carrier trails of the SEPECAT Jaguar “M” prototype aboard the French aircraft carrier Clemenceau in July 1970.

From Wikipedia:

An “M” prototype flew in November 1969. The “M” had a strengthened airframe, an arrestor hook and different undercarriage: twin nosewheel and single mainwheels. After testing in France it went to RAE at Thurleigh for carrier landing trials from their land based catapult. In July 1970 it made real take offs and landings from the French carrier Clemenceau. From these trials there were doubts about the throttle response in case of an aborted landing; the shipboard testing has also revealed problems with the aircraft’s handling when flying on one engine, although planned engine improvements were to have rectified these problems. The “M” was considered a suitable replacement for the Etendard IV but the Aeronavale would only be able to purchase 60 instead of 100 aircraft.

Furthermore, the Jaguar M was expensive, limiting the size of the force the French Navy could afford. In 1971, Dassault proposed the Super Étendard, claiming that it was a simpler and cheap development of the existing Étendard IV, and in 1973, the French Navy agreed to order it instead of the Jaguar, although rising costs of the Super Étendard meant that only 71 of the planned 100 aircraft were purchased. The M was cancelled by the French government in 1973.
