The cheaper Revenge-class design was crowded, which made later modernization harder than in the larger Queen Elizabeth class or Hood. A bigger capital ship cost more and could enter fewer ports, but it retained internal volume for moving machinery and fitting new equipment. Designers could also remove existing top weight to make room for additions. A third Renown-class battlecruiser would trade one turret for more horsepower and gain useful space for upgrades. Keeping another British capital ship might also prompt the United States and Japan to seek an additional ship of their own.

Why a third Renown-class battlecruiser might modernize well
A proposed third Renown-class battlecruiser becomes a design lesson about internal volume, weight margin, and the ability to accept interwar upgrades.
