Battlecruisers as sea-control tools

Battlecruisers are treated here as a distinct type rather than failed battleships. Their speed and endurance suited scouting, hunting enemy ships, denying the enemy use of sea space, economic warfare, and information gathering far from base. The Battle of Jutland demonstrated the danger of placing them in the battle line, where their protection could not match a battleship's. Treaty definitions that grouped battlecruisers with battleships narrowed the opportunity to retain a distinct fast force and encouraged what the discussion calls the false battleship. In this interpretation, that classification was a political success for the United States because it prevented Britain from preserving separate capital-ship categories and capabilities. A counterfactual Pacific-first war places battlecruisers with carriers in a fast wing operating from Singapore, a mission closer to their intended reconnaissance and sea-denial role.
