Lexington carriers and the scout-force tradeoff

Converting the Lexington-class battlecruisers into carriers removed the intended leaders of the scout force and exposed the limits of treating carriers as self-defending surface ships.

Notes

The U.S. scout fleet was originally supposed to be led by the Lexington-class battlecruisers, whose speed and firepower suited the role of finding an enemy and escaping stronger opposition. Their conversion into aircraft carriers preserved reconnaissance value but made it dangerous to place them at the tip of the spear. Their eight-inch guns also clarify the difference between the Washington Treaty, which left the United States free to build more cruisers below 10,000 tons, and the later London Treaty tonnage limits that briefly made carrier-mounted cruiser guns easier to defend. Carriers needed escorts and room to withdraw, while cruisers inherited the forward scouting role.
