Chief of Naval Operations (CNO) Admiral Gilday’s December 2019 Fragmentary Order (FRAGO), “Design for Maintaining Maritime Superiority,” emphasizes the importance of building alliances and partnerships to enhance U.S. warfighting capability, with a particular focus on “full interoperability at the high end of naval warfare.” This objective is critical—Washington’s ability to credibly threaten combined warfare across the full range of the competition to conflict spectrum enhances its ability to deter war and improves its ability to win if forced to fight one.
