Another twenty battleships and battle cruisers (three more "classes") were begun or planned, but not completed. During this almost six-decade-long era, 59 battleships of 23 different basic designs (or "classes") were completed for the Navy. Navy battleship construction began with the keel laying of the Maine in 1888 and ended with the suspension of the incomplete Kentucky (BB-66) in 1947. For the sake of completeness, these two ships are included at the beginning of this page's "BB" series. In addition, the Navy's first two "modern" battleships (rated as "Second Class Battleships") never received hull numbers.

For convenience, all of these ships are listed below under the appropriate numbers in the "BB" series. They were, however, referred to by "Battleship Number", with that number corresponding to the "BB" number formally assigned in July 1920, or which would have been assigned if the ship had still been on the Navy list.

Navy Battleships did not officially have "BB" series hull numbers.
