Fisher would still build battleships, carriers, destroyers, and submarines because all four fit concerns he had expressed during his original career.

Carrier primacy retains modernized 15-inch-gun ships but directs the most aggressive development toward aircraft, escorts, and underwater attack. This assessment makes aviation the likelier winner because speed offers more operational return in aircraft than in already-fast ships.
