Given the shenanigans in Turkey atm, pinning a 3-400 cab order in that direction is - I would suggest - somewhat ambitious.
Yeah, sorry if that wasn't clear, that was an estimate for the combined orders of all the nations listed.
You are assuming that there is a need for a large USAF tacair force which will struggle to play in WestPac.
How are you coming to the conclusion that the air force tacair won't have much of a role though? It's well placed to provide a huge impact from Korea, Japan and if needs be, Taiwan. Yes, it's not as flexible as having them on a boat, but both have just as many positives and negatives as each-other. And with the likely numbers of carriers/amphibs you would be looking at around a maximum of 4 each in theatre at any one time...
