The Jag 'M' always struck me as a rather bad idea - yes its undercarriage was strong but the relative lack of thrust and poor engine out performance seemed to stand against it. Isn't it a bit underfinned as well, making low speed high-ish AOA handling quite tricky, also counting against its suitability?
I did read a story about the Jag M being rejected by the French Navy because of its poor engine out performance - the irony being that the aircraft they ended up with, the Super Etendard, had even worse engine out performance.........politics and patriotism were always against a navalised Jag for the French anyway.
