Changes

"Perhaps John Galt could design a new quantum-assisted hydrogen-burning turbofan with which Ragnar could retrofit a squadron of F/A-18 jet fighter-attackers, thus giving them extra range or even a boost in speed"

There is also no possibility whatsoever that Ragnar could use a carrier for shore bombardment; it carries no heavy guns, only a few 20mm Phalanx cannon for point defence. On the subject of defence, it barely has any: assuming that any other country has ANY navy left, all they have to do is send a destroyer close in to the carrier during a storm, when it can't launch aircraft, and pound it to bits with torpedos, missiles and finally short-range gunfire. No US carrier ever goes anywhere without an entire surface battle group and two submarine escorts, and there's a reason for that: carriers are defenceless unless they can fly off aircraft.
