Appearance Notes.- Revenge differs in having sternwalk and extra heavy forebridge. Details of bridge vary in each ship away. 4 inch AA. Mounted in place of former 3 inch AA, in 1924-25. Two superstructure 6 inch removed in 1927-28.
Armour Notes.- Thicknesses much as Queen Elizabeth class, but armour differently distributed. Barbettes 6"-4" as they decend behind belt. Gunhouses, 13" face, 11" sides and rear; crowns 5". In these ships 2" protective deck has a high 2" slope behind belt, so that flat part of protection can be put on main deck and at top of belt, instead of a deck lower. Internal protection is very good, and with protective bulges, defence against underwater attack is very strong. All refitted with bulges, which in Ramillies were the first to be fitted to any battleship; they extended almost to level of battery, but have since been replaced.
Engineering Notes.- Designed to burn coal, but while building "all oil fuel" was adopted, so that 23 kts. Would be secured with the resulting increase of H.P. Addition of bulges has brought speed down again to about 22 kts. Main turbines are direct drive, cruising turbines geared.
General Notes.- Begun under 1913-14 Estimates. Ramillies injured herself at launch and was delayed in completion. They are fine ships, but suffer rather from reduced freeboard. Searchlights on mainmast removed 1922. Refits: Ramillies and Resolution, 1926-27; Revenge, 1928; Resolution, 1930; Revenge, 1936-37; Resolution, 1937-38; Ramillies, 1938-39; Royal Oak, of this class, sund Oct. 14, 1939. Royal Sovereign transferred to Soviet Navy in 1944.
Cost.- Averaged about GBP 2,500,000.
