Eight Renowns would make speed the Royal Navy's interwar standard

How would Royal Navy strategy change if all R-class ships had been completed as Renown-style battlecruisers?

Eight Renown-type ships would likely become the main modernization priority and create a fast battle line suited to carrier operations.

Converting the five R-class battleships and completing all three Renowns would give Britain eight similar fast capital ships. Such a large class would likely receive priority for interwar modernization because it would be the navy's most numerous heavy type. Each ship would carry only six 15-inch guns, but a speed above thirty knots would let the formation choose engagements and operate naturally with carriers. The Admiralty-class program might then emerge as heavier battleships instead of another battlecruiser line. The result would be a fleet structurally different from the historical mix of slow standards and a few fast ships.
