SynopsisPower and energy have become a strategic and operational imperative for both the Royal Navy and United States Navy. The 21st century pace of change is unparalleled, with threats evolving at increased range, complexity, and sophistication. State and non-state adversaries are gaining technological advances and expanding their ability to conduct combined operations. Rapid fielding and seamless integration of advanced power and energy capabilities, such as power continuity across systems and electrically-powered weapons and sensors, will be critical for allies and partners to keep pace. As energy is one of the primary drivers for enhanced warfighting capability, these capabilities will be spurred by advances in power, energy and integrated system level controls. Further, the evolution of asymmetric threats will require disruptive and technologically superior solutions that create resilient networks and operate in a fully distributed manner.
