Can the same forecast be made for smaller navies?

Could the same no-World-War-II fleet forecast be extended to the smaller navies?

Not with the same confidence; their choices are too weakly constrained by surviving plans, while most Commonwealth construction belongs within the British forecast.

The major powers left multiyear building plans and industrial programs from which a counterfactual can be reasoned. For Polish, Swedish, Dutch, Greek, and Turkish fleets, the surviving evidence does not constrain whether they would compete, buy abroad, or remain limited. Commonwealth construction is largely included within the wider British forecast rather than treated as a separate minor-power program. A detailed smaller-navy projection would therefore cross from evidence-grounded extrapolation into unsupported speculation.
