They would do well to purchase or license American Essex class LHD and Tarawa class LHAs.
40,000t and designed for fixed wing VSTOL aircraft, with plenty of room for fuel and maintenance/weapons.
Most folks don’t know we have 10 of these and they all can carry about a dozen F-35b’s along with another 30 helos.
Proven design and capability.
That’s almost as big as France’s only carrier, (India’s too), and larger than those of Italy, Spain, or Turkey.
All of our Tarawa class are retired though, correct? I am reading that we presently have operational 8 Wasp Class LHD’s (including the Essex - LHD-2) and 1 America Class (45,000t) with 10 more of the latter planned.
The WASP’s can carry up to 20 F35B’s (if they don’t take ‘copters along) — according to Wikipedia as many as 24 Harriers have been accommodated.
I pondered this a while: Of course it would never happen this way, but leaving the British out of the fight, our amphibious assault ships could in most scenarios defeat all the other carriers in the world. (Ok, if the Chinese get a couple more carriers built, bring in the Brits or the under-construction Italian carrier on our side.) Then our LHD’s land the Marines.
