HMS Rutherford's American-built origin

HMS Rutherford, K558, was an American-built escort that served in the Royal Navy as a Captain-class frigate. She was originally constructed in the United States as a Buckley-class destroyer escort, so the American and British classifications refer to the same ship. Her Royal Navy service lasted from 1943 to 1945, in the final years of the Second World War. Her work as a coastal-forces command frigate formed part of the Royal Navy's response to E-boats.
