Unlike contemporary foreign battleships and the preceding "Nelson"-class battleships, the "King George V" class had comparatively light conning tower protection with 4 inches (100 mm) inches sides, 3 in (75 mm) forward and aft and a 1.47 in (38 mm) roof plate. The RN's analysis of World War I revealed that command personnel were unlikely to use an armoured conning tower, preferring the superior visibility of unarmoured bridge positions Stability and weight considerations clearly played an important part in the British decision to limit superstructure armour. The conning tower armour was sufficient to protect against smaller ship guns and shell fragments.
