Three changes for US Navy effectiveness in the Pacific

What three changes would most improve US effectiveness in the Pacific in 1941-42?

The answer prioritizes more oilers, a corrected Mark 14 torpedo, and completing a pair of Lexington-class battlecruisers to give carrier forces faster, heavier support.

The answer puts logistics and weapons reliability ahead of a single prestige solution. More oilers improve operational reach, while fixing the Mark 14 addresses the effectiveness of submarine attacks. Completing fast Lexington-class battlecruisers would add confidence and weight to carrier forces, particularly through air-defense support and a stronger surface presence early in the war.
