Project history: Roberts was built by the 1940 program under modified Erebus design with shorter hull, some smaller machinery power and geared turbines instead of steam machines. In comparison with a prototype they had more developed superstructure and outwardly resembled Nelson class. Roberts received 381mm turret from monitor Marshal Soult. The second ship of this class Abercrombie was armed with a turret in due time ordered for a battlecruiser Furious. She differed from leading ship by arranging of 102mm guns, they were raised by one deck level.
Protection: Main belt extended between barbette and main mast and sloped outwards along the top of bulges. Abercrombie has a greater area of 102mm deck armour than Roberts. Main deck over main magazines was raised and has 152-102mm glacis. There was also 38mm splinter protection for magazines. Thickness of lower deck over steering gear was 76mm. Underwater protection depth was 5.2m, there was 38mm torpedo bulkhead.
