Can you point out the bit that supports your assertion that the 'Americans' are telling the 'British' what carriers to build because nothing you have presented says that - only that Admiral Sir Alan West's 'oppo' in the US agreed that the RN having them was a good idea.
Um... it's black on white on what i quoted from wikipedia by that Alan West, i quote it again
So the americans wanted the british to have these carriers and with the same "clout" as one of theirs, which is the 36 aircraft figure the QE was designed around. Meanwhile the powers that be kept changing their minds between VSTOL and CATOBAR then back to VSTOL...I have talked with the CNO (Chief of Naval Operations) in America. He is very keen for us to get these because he sees us slotting in with his carrier groups. For example, in Afghanistan last year they had to call on the French to bail them out with their carrier. He really wants us to have these, but he wants us to have same sort of clout as one of their carriers, which is this figure at 36. He would find that very useful, and really we would mix and match with that.
Again, if they really want the damn VSTOLs, at least it would have been cheaper for the country to build the things with the same "clout" as an american LHA and be done with it.
On a more general note, it seems the traditional incompetence, political interference and simply bad choices of FAA just continues to this day, you know the history of the pitiful condition of FAA in 1939, some of the wrong conceptual decisions of the aircraft and ships taken back then, the steady decline after WW2 culminating in the sad story of CVA01 and the abolition of RN true carriers, and now the story of the QE class hermaphrodites, neither fish nor fowl...
As the french has been brought into this, the fact is up to now at least they gealously guarded their technological know-how and tried to maintaining their self-sufficiency, they never gave up on true carriers and true carrier planes (see CdG and Rafale), pity for them they didn't got to build a sisterhip for CdG (i have read some recent news on that, seems the subject is revived?). If the british would have built the CVA01 class, and today there would be a Sea Typhoon to fly off QE, they would have rightly been in the same league as the french, but as it is now... no comment.
