Why a larger modern reserve fleet remains unlikely

Will limited shipbuilding capacity lead modern navies to expand their reserve fleets?

It would be sensible, but a meaningful expansion is unlikely without sustained funding and political commitment.

The question links a small active fleet and limited building capacity to the value of stored warships. A larger reserve fleet is described as sensible and desirable. The answer is nevertheless pessimistic about whether a meaningful expansion will happen. It offers no detailed programme or estimate, so the watch point records the preference and its stated uncertainty.
