G3 and N3 construction would upset the Pacific balance

Building the British G3s, and especially following them with an N3-derived design, would create a serious force-structure problem for both Japan and the United States.

Question

How would Japanese ships measure up if Britain and the United States completed more of their 1920s capital ships?

Short answer

Japan would face a serious imbalance, especially if Britain completed the G3s and followed them with an N3-derived class.

Notes

This is a qualitative force-balance judgment rather than a ship-for-ship battle simulation. Completing the G3s would place Japan and the United States under immediate pressure to answer a powerful British fast-capital-ship programme. A follow-on design derived from the N3 concept would increase that pressure further. The uncompleted building programme could alter naval diplomacy and procurement before any of the ships met in battle.
