Maintenance ships reveal strategic reach

A fleet cannot rely indefinitely on friendly shore facilities. A floating workshop can turn a limited port into a serviceable repair base or keep work moving after bombing disables installations ashore. Britain and the United States diverted precious new merchant hulls to this purpose even during the worst convoy losses because fleets in the Pacific, Indian Ocean, Mediterranean, and Atlantic could not operate without them. The ships therefore represent combat power rather than administrative overhead. The same measure applies to modern naval ambition: a force becomes more serious when it can restore and support operations away from established bases. Building mobile repair capacity also signals preparation for fighting a peer able to attack fixed infrastructure.
