HMS Vanguard was operational, even without a wartime battle role

Was HMS Vanguard ever fully operational, or was she only a training ship?

She was operational, but her limited postwar employment resembled that of a very heavy cruiser rather than a traditional battleship.

HMS Vanguard became operational and took part in naval activity, despite never serving in a wartime battleship operation. By the period in which she could be employed, the traditional battle-line role had largely vanished. Her practical use was closer to that of a very heavy cruiser. Operational status should not be confused with the absence of a classic battleship mission.
