Where British battleships were actually needed

How far abroad did Royal Navy dreadnoughts deploy compared with battlecruisers?

Battlecruisers traveled more widely; battleships concentrated in theaters where their protection and heavy guns were operationally necessary.

Battlecruisers made many of the Royal Navy's distant movements because their speed suited pursuit, reinforcement, and widely separated stations. Battleships stayed concentrated around missions where their protection and heavy guns were operationally necessary. Those missions included the North Sea and its approaches, Arctic-convoy cover, the Mediterranean, and eventually the British Pacific Fleet. American battleships likewise concentrated in the Pacific, with selected ships supporting major Atlantic landings. Deployment followed strategic demand rather than a need to prove that every dreadnought possessed worldwide endurance.
