The entry on PA58 in Conway's 1947-95 says that the ship was to have operated a navalized Mirage IV designated Mirage IVM. Whether it would have worked in practice is another matter.The French may be chauvinistic but they are not crazy. They would not want to operate something the size and wing platform of the Mirage IV off of a carrier. The F2/3 is a remote possibility. The G is better. It has variable sweep wings. The reason why the French have bought American for carrier aviation has been because American produced planes were cheaper.
