How would naval design change if the Invincible battlecruiser concept failed and Blucher-like armored cruisers proved preferable?
Short answerBattleships would likely become faster, while a large heavy-cruiser category might persist, but the early ordering cycle makes a timely rejection of battlecruisers hard to arrange.
NotesBattleship speed would probably rise sooner, bringing something like the Queen Elizabeth concept forward. Large armored cruisers might survive as a separate heavy-cruiser type near 20,000 tons. Successor battlecruisers were ordered before the first generation entered service, so failure would need an unusually early and persuasive cause.
