At the end of WW1, the Royal Navy decided to design future capital ships incorporating all the lessons that they had learned during the war. The result was a battlecruiser design, labelled G3, capable of over 32kt, with 9x16in guns and heavy armour and a battleship design, lablelled N3, capable of 25kt, with 9x18in guns with even thicker armour than the battlecruiser. These magnificent ships were never built but were sacrificed at the Washington disarmament conference against a promise that britain could build two 16in gun battleships to match existing ships building in USA and Japan. Nelson and Rodney were built on a cut down hull from the N3 design and the guns and turrets from the G3 battlecruisers. Rodney and Nelso entered WW2 with only minor modifications from new and it is reasonable to assume that the N3s would have been the same. Ships based in Scapa Flow as guard ships were given camouflage to make them less visible against the island background and an N3 has been given the green, brown over light grey pattern applied to HMS Rodney in 1940,
