Which modern Commonwealth patrol vessel would be the best platform for a mass-produced escort in a global war?
Short answerThe Harry DeWolf class is the strongest starting point, with River-class ships another option, because their size and endurance leave room for an emergency escort fit.
NotesA mass-produced escort needs an existing hull large enough to accept additional sensors, weapons, boats, and crew. The Harry DeWolf class and River-class patrol vessels offer practical Commonwealth foundations. Their patrol origins favor endurance and seakeeping over the tightly optimized combat systems of a frigate. Turning either into a wartime escort would still require simplified production choices and a mission-specific anti-submarine and air-defense fit.
