Team Submarine, a grouping of submarine programs within the Naval Sea Systems Command (NAVSEA)—the largest of the U.S. Navy’s six system commands—is a combination of Program Executive Office (PEO) Strategic Submarine (PEO SSBN), PEO Attack Submarines (PEO SSN), and PEO Undersea Warfare Systems (PEO UWS). The Team Submarine concept divides the single submarine-centric organization into specific PEOs with the goal of enhancing the structures and processes in the submarine research, development, acquisition, and maintenance communities. Team Submarine provides exceptional communication among the various offices that contribute to the overall success of the United States Submarine Force.
