What the Pacific Fleet could take to sea

Seven battleships were readily available, with Pennsylvania and possibly Colorado offering ways to enlarge the battle line if a major diplomatic demonstration had been prepared. Four Brooklyn-class light cruisers - Phoenix, Honolulu, St. Louis, and Helena - and two heavy cruisers were too few both to screen the battle line and to conduct wide reconnaissance. The gap reflected an interwar force structure in which Congress had maintained battleships and destroyers more consistently than the cruiser arm. Destroyer Flotillas One and Two could supply escorts, but the second flotilla needed carrier-task-force destroyers to become a full two-squadron formation. Catapult aircraft from cruisers and battleships offered some search capacity, yet not enough to replace a true scouting force. That made a rendezvous with Lexington and Enterprise central: carriers had inherited the reconnaissance role once associated with American battlecruiser plans, a connection that Kimmel understood from his Scouting Force background.
