What if Hood's sister ships had been converted into aircraft carriers?
Short answerBritain might have gained three very large carriers comparable to Lexington and Saratoga, probably carrying about eighty aircraft and operating with strong escorts.
NotesHad the unfinished Admiral-class hulls been far enough advanced, Britain might have converted three ships comparable to Lexington and Saratoga. Their greater size could have supported about twenty more aircraft than Courageous and Glorious, bringing the estimate toward eighty. Carriers of that scale would likely have been treated as front-line assets and kept with substantial escorts. The counterfactual connects Washington Treaty timing to the carrier force Britain actually possessed in the Second World War.
