Why interwar fleet totals need matching planning horizons

British, American, and Japanese treaty-era fleet totals can mislead when they count plans from different years.

Question

How should British, American, and Japanese capital-ship plans be compared around the Washington Treaty?

Short answer

Use the same planning horizon and include overlooked British ships such as Tiger and the King George V class before comparing totals.

Notes

A comparison that gives Japan the same fleet size as Britain and the United States may be mixing different planning horizons. The British total must include Tiger and the King George V class alongside the G3 and N3 programmes already under discussion. American and Japanese plans extended further into future construction, while British announcements covered the current and following year's orders. A fair comparison has to align which ships are in service, under construction, or still planned before treating the totals as equivalent.
