The Lexington design fits an American doctrine built around finding the enemy for a powerful standard-type battle line. Its purpose follows the reconnaissance and commerce-war lessons associated with Coronel and the Falklands. Its speed and heavy guns make it useful at distance from the main body even though its protection invites familiar criticism. Pairing the force with a carrier conversion of USS United States would also let the navy experiment early with a fast scouting group supported by aviation.

Five Lexington battlecruisers give the slow American battle line a fast arm designed for reconnaissance, economic warfare, and independent support rather than equal-line combat.
