Type 31 and Type 32 as forward-presence ships

How would Type 31 and Type 32 frigates differ from River-class ships in forward presence?

The frigates would provide more capable global presence, while River-class ships would serve as lighter force multipliers for less demanding deployments.

Type 31 and Type 32 are treated as globally deployable ships able to show the flag with greater combat power than patrol vessels. In that presence role they resemble light cruisers rather than ships confined to carrier escort. River-class vessels fill a different, lighter role comparable to sloops. Those ships can handle less demanding stations and multiply the fleet’s reach without committing a frigate to every task. A layered mix preserves higher-end escorts for surge operations while sustaining routine visibility around the world.
