New additions to the fleet were therefore minimal during the 1920s, the only major new vessels being two Nelson-class battleships and fifteen County-class cruisers and York-class heavy cruisers.
Tilføjelser til flådens tal var derfor ganske begrænset under 1920'erne blev kun to nye slagskibe (Nelson-klassen) samt femten nye tunge krydsere af County- og York-klassen.
