Fisher's cuts and the wartime uses of older ships

What real-life cases resemble the old Constitution in Legacy Fleet?

Some ships removed in Fisher's cuts could have remained useful on constabulary duties, freeing other ships for war.

Fisher's disposal of older ships supplies the proposed real counterpart to Constitution. The criticism accepts that the cuts had a rationale, while arguing that keeping some vessels could have provided useful capacity when war came. A ship returning from deployment must enter a major refit if it needs one. If its refit is routine and it remains usable, however, a worn ship can take over constabulary duties despite being unsuitable for battle. That substitution releases another warship for combat.
