The G3 and N3 program already implied retirement of Britain's older capital ships

The Royal Navy expected its R-class, Iron Duke-class, Lion-class, and Tiger-era ships to disappear as the G3 and N3 replacement cycle advanced.

Question

When did the Royal Navy decide that its older R-class, Iron Duke-class, Lion-class, and Tiger-era capital ships would be gone by the 1930s?

Short answer

The expectation was already built into the pre-treaty G3 and N3 replacement program, before the treaties disrupted that path.

Notes

The retirement logic predates the final treaty outcome. Continuing the G3 and N3 evolution would have brought new capital ships into service and displaced older battleships and battlecruisers. By the 1930s, the inherited R-class, Iron Duke-class, Lion-class, and Tiger-era force would therefore be leaving the fleet. The treaties changed the construction path, but not the age-driven need for replacement.
