Would proposed super Tigers have been a better choice than the R-class battleships, and would they have aged better?
Short answerA mixed force was preferable: the Royal Navy needed additional 15-inch battleships as well as more fast R-class battlecruisers.
NotesA balanced programme of four R-class battlecruisers and four R-class battleships would have been preferable to replacing the whole class with fast ships. The battleships preserved a modern 15-inch battle line, while the battlecruisers added speed that would become especially useful in later service. This treats procurement as a fleet-mix decision shaped by different operational needs. Comparing the two designs in isolation misses the value of having both.
