although the spec for f-35ac is 700kt speed limited to M1.6, it's been reported that the f-35a does 750kt and speed limited to M1.6, so the alt is important too and there is no mention of it in any statement
further to that, Hog who said it cruises with min AB. also on f-16net is said to say when asked, the f-35A does M1.25 without AB
