How Britain might have continued after N3 and G3

Beyond four N3s and four G3s, what did Britain intend to build in the 1920s?

Likely a restrained four-ship cycle if rivals stayed quiet, with more construction only if another naval arms race emerged.

Britain's planned four N3 battleships and four G3 battlecruisers were probably an opening response to the postwar situation rather than a complete long-term program. Those orders would have tested what rival powers did next without committing Britain to indefinite expansion. If other powers built little, Britain might have moved to classes of four, laying down two ships at a time over a four-year cycle. Faster foreign construction would instead have drawn the Royal Navy into additional building, since the restrained rhythm assumed that no new naval arms race emerged.
