What if the York class had been a 10,000-ton F3-style cruiser with nine 8-inch guns forward?
Short answerIt would be a much stronger design, and eight of them could be worth more to the Royal Navy than two additional Illustrious-class carriers.
NotesConcentrating three triple 8-inch turrets forward would shorten the armored citadel and leave room for useful secondary guns, speed, and protection on a treaty-cruiser hull. This concept is far stronger than the underarmed York class. Eight capable heavy cruisers would reinforce the Royal Navy against both Italy and Japan across multiple stations. That fleet-wide utility makes the exchange for two Illustrious-class carriers genuinely competitive rather than an easy rejection.
