This Strategic Plan describes how the C4ISR Department's (ONR Code 31) vision, mission, philosophy, structure, and processes support the execution of scientific research efforts that will enable future operational concepts of the Navy and the Marine Corps. The priorities of the Chief of Naval Research (CNR) and the C4ISR Department Head are reflected in the shape of the Code 31 investment portfolio described in this document. The principles for S&T management outlined below are intended to drive the development of technologies that enable new discoveries as well as develop and demonstrate high-payoff, game-changing capabilities. These capabilities will ensure that the Fleet/Force retains a significant advantage over potential adversaries within the Information Dominance domain. Information-based warfare will be fundamentally transformed from today's paradigm. Today, data resides in mission specific networks, sensors and communication architectures. Information requirements are tied to a mission or mission phase where information for prosecution is generated and held for each mission in separate networks.
