Yes. Besides the 42 Crusaders procured, only 90 Etendard IVM/P and 71 Super Etendard were built. Jaguar M procurement plans: 100 or less.
There was a 1958 RFP for a Mach 2 naval fighter, one competitor being my all time favorite Breguet fighter design: the Br.1120 Sirocco. It was very much a Mirage F1 a decade before the F1, their similarities are striking. Then again, there are not that many ways of designing a Mach 2 fighter with Atar 9, swept wings, and "mice" in the air intakes.
But the RFP went nowhere, too expensive for a smallish fleet.
Funny to think that at the same moment the USN actually had too many (almost) Mach 2 fighters on its plate
