Project history

Ships of the class were designed under 1925 Programme and repeated Kent class but had more traditional hull form (without bulges) and a fwd superstructure moved aft by 7.5 m for improvement of horizontal aiming arcs of "B" turret.

London in 1939-1941 passed the major modernization. She received narrow armored belt abreast machinery. Fwd superstructure was completely rebuilt, becoming similar on standing on King George V class battleships. Boiler uptakes were deduced into 2 funnels. The longitudinal catapult and large hangar are fitted.

Protection

Magazines were protected by 111 (102mm armour on 9mm plating) - 25mm sides and 76 - 25mm platform deck. Machinery was protected by 25mm bulkheads and 32mm deck. Steering gear had 38 - 25mm horizontal protection.
