How a treaty-free imperial battlecruiser programme might develop

Without a Washington-style treaty, how many battlecruisers might the British Empire build?

The Royal Navy would probably establish G3s first, then build successors for dominion fleets as fast global units became more important.

The G3 concept fits the Royal Navy's growing emphasis on global manoeuvre warfare in the 1920s. Britain would probably establish the G3 and N3 generation before turning to later fast capital ships. Successors could replace the battlecruisers associated with Australia and New Zealand and perhaps equip Canada. The imperial total would emerge over successive programmes rather than from one fixed building batch.
