Would the Royal Navy rather have two Illustrious carriers, six Yorks, or six Rulers in 1938?
Short answerTwo Illustrious-class carriers; Yorks are poor value and six escort carriers do not compensate for losing two armored fleet carriers.
NotesThe Yorks are criticized as nearly as expensive as Counties while being slower and less heavily armed. Escort carriers can be extremely valuable, but the number offered is too small to justify giving up two modern armored fleet carriers. Illustrious-class ships bring speed, protection, and concentrated air power that the smaller alternatives cannot reproduce in this package. The choice follows intended operational effect, not merely hull count.
