Maritime Dominance in the 21st Century calls for naval forces that can project power forward, provide assured access in the littoral environment and support a wide variety of joint and combined operations. To meet this challenge, the U.S. Defeating and deterring future national threats requires a broad range of capabilities from long-range missile defense, precision strike and volume fires to assuring friendly access in the dangerous littoral regions of the world. Transformation of the future fleet will start with the DD(X) technology development effort, from hull and propulsion to sensors and weapons. DD(X) will provide sustained, offensive, distributed, and precise firepower at long ranges to support forces ashore and to conduct time-critical strikes on land targets.
