Think the term 'battleship' for Cardiff etc is wrong. Battleships are heavily armoured with significant fire power: Galahad was a landing ship and the various Sheffield in service have either been a destroyer, frigate or light cruiser, none of which would be considered a 'battleship'. 'Warship' should be the only term to cover these vessels, but this is not accepted as an answer.

Yeah. RN Ships didn't work.
