Fleet size depends on a judgment about sufficient capability and the cost of acquiring more. The Spanish comparison recalls a cut in the Álvaro de Bazán order, followed by additional F110s proposed for a similar role after requirements changed. That example concerns numbers, while Pohjanmaa and ASWF also illustrate the value of room for a ship's capabilities to expand. A vessel expected to remain in service for twenty or thirty years must allow for changes in the strategic environment. Extra hull capacity can keep later equipment and missions feasible when the original fit no longer meets requirements. The recommendation favours acquiring sufficient capability and room to adapt before a crisis creates urgent demand.

Room to expand capability helps a ship adapt as strategic requirements change over twenty or thirty years.
