The French Crusaders were based on the F-8E, but were modified in order to allow operations from the small French carriers, with the maximum angle of incidence of the aircraft's wing increased from five to seven degrees and blown flaps fitted. The aircraft's weapon system was modified to carry two French Matra R.530 radar or infra-red missiles as an alternative to Sidewinders, although the ability to carry the American missile was retained. Deliveries of the new aircraft, dubbed the F-8E(FN), started in October 1964 and continued until February 1965, with the "Aéronavale"s first squadron, "Flotille" 12F reactivated on 1 October 1964. To replace the old Corsairs, "Flotille" 14.F received its Crusaders on 1 March 1965.
