A 30,000-ton carrier duplicates capabilities the US Navy already has

Could a 20,000- to 30,000-ton carrier solve the US Navy's fourth-rate requirement?

Probably not, because a carrier at that scale adds little that the Navy does not already obtain from its large amphibious assault ships.

A cheaper carrier is useful only if it supplies a distinct capability at an affordable scale. The United States already operates amphibious assault ships capable of carrying substantial aviation groups. A 30,000-ton carrier would therefore reproduce much of an LHD's contribution without automatically solving the need for an independent surface combatant. An off-the-shelf foreign medium-carrier design might be examined, but the Sea Control Ship concept has a long institutional afterlife in the US Navy. That history makes the proposal more than a question of hull size because officers inherit memories of earlier force-design disputes. Fleet planning should begin with the capability gap and institutional context rather than with an attractive ship category.
