The offshore patrol vessel inherits the armed trawler's role

Should the Royal Navy revive the armed trawler for modern operations?

Its functional successor already exists in the offshore patrol vessel, which combines economical presence with modest armament.

A modern offshore patrol vessel already performs much of the work once assigned to armed trawlers and small sloops. It provides persistent presence, patrol capacity, boarding support, and a modest armed response without the cost of a frigate. Its weapons are limited because constabulary and low-threat duties matter more than fighting peer warships. The historical label has changed, while the need for an economical small ship between civilian craft and fleet combatants remains.
