Yeh, Hitler was obsessed with big dreadnaughts; Bismarck and Tripitaka were the first two which were obsolete before built. The aircraft carrier has replaced the battleship since December 7th, 1941 as the capital ship. But, now however, it appears (to me) that the carrier may be approaching its demise. It appears that hypersonic long range missiles which can be launched in-mass have the ability to overwhelm a carrier battle group and take out a carrier before it approaches aircraft range to lunch an attack. And, these missiles are relatively cheap when compared to a carrier battle group.

Just not yet technically feasible. From testing failures I’d guess that we’re at least a decade away from fielding hypersonic missiles. Meanwhile, like the battleships of WW2, the modern aircraft carrier will soldier on.
