Why capital ships could remain central after a shorter war

What would navies look like in the 1950s after this shorter war?

Jets and angled-deck carriers would still develop, but new fast battleships could remain central to task groups into the 1960s and perhaps serve into the 1970s or 1980s.

Jet aircraft and angled flight decks would still develop, and carriers would grow. Fast battleships could remain major components of task groups because the historical losses of Force Z would not have occurred and capital ships would have contributed to Allied operations. A possible battle between reinforced British-Japanese forces and Bismarck, Scharnhorst, and Gneisenau could provide another argument for retaining them. New fast battleship classes might therefore be built in the 1950s and even the 1960s, with ships serving into the 1970s or 1980s.
