Why a flagship needs room for a command staff

Were these large surface combatants designed with enough space to serve as command ships?

A real flagship needs substantial extra volume for several watch teams, accommodation, secure communications, information processing, and survivable command facilities.

Round-the-clock command work multiplies each watch position into several people who need sleep, food, clothing storage, sanitation, and relief coverage. Secure communications, workspaces, protection, and subdivision consume more volume, so hiring a cruise liner would also create a new escort and survivability burden. The 1982 Falklands experience showed why remote command from Britain was inadequate. Fearless and Intrepid had a cramped command room, while later spaces in Albion and Bulwark could accommodate about 150 people. Queen Elizabeth and Prince of Wales likewise matter as local command and information-processing platforms because formations must organize the best information available and make decisions immediately. A flagship therefore needs a sustained command organization rather than an extra room added to an ordinary hull.
