Renown and Repulse show another design path

Renown and Repulse weaken the claim that construction urgency made the R class inevitable. The two battlecruisers were developed quickly from Queen Elizabeth-class ideas, with an evolution in armour distribution. Their design shows that British naval architects could adapt the more capable lineage under time pressure. The R class was therefore one choice among practical follow-on designs rather than the only route to rapid construction.
