What is known about this ship

The K525 hull entered commissioned service with Canada as HMCS Ribble and later returned to Royal Navy identity without creating a second physical ship.

Class context: River class frigate

The River class was the first mass-produced Allied ocean frigate design of the Second World War, combining Flower-class-style economical machinery and merchant-yard construction practice with a larger twin-screw hull suited to North Atlantic escort work.

This ship is recorded as a member of River class frigate. Shared design history belongs on the class page; this page concentrates on the individual hull where evidence is available.
