During the procurement of SS, when it was still SR(A)1236,Typhoon was recommended for strengthening in the wing pylon area for SS but I don't think that it has done any proper flight trialling with the beast yet, but I may be wrong. If I am, then I don't believe it has been 'declared' yet with SS. Harrier was originally in the plan for SS but it was decided that it would be a no-goer off the deck and so.......................
Correct answer, too early yet. GR4's a very capable aircraft and has at least 9 years left in it to the projected OSD (at least that was true when I was last involved with these kind of things).
Now I am more interested in getting my golf handicap down!
