Engineoil Degreaser

Directed energy weapons (DEWs) are defined as electromagnetic systems capable of converting chemical or electrical energy to radiated energy and focusing it on a target, resulting in physical damage that degrades, neutralizes, defeats or destroys an adversarial capability. Navy DEWs include systems that use high-energy lasers (HEL) that emit photons and high-power microwaves (HPM) that release radiofrequency waves. The U.S. Navy uses DEWs for power projection and integrated defense missions. The ability to focus the radiated energy reliably and repeatedly at range, with precision and controllable effects, while producing measured physical damage, is the measure of DEW system effectiveness. Conversely, capabilities to increase the resilience or survivability of platforms or Sailors from DEW threats are part of the Counter Directed Energy Weapons (CDEW) program.

ONR has three weapons-oriented research concentration areas: High Power Microwaves (HPM); Ultra-Short Pulse Laser (USPL) and Atmospheric Characterization; and Counter-Directed Energy Weapons and High Energy Lasers (CDEW & HEL).

Ultra-Short Pulse Laser (USPL) and Atmospheric Characterization initiatives explore the scientific limitations of DEW. Of particular research interest are efforts that offer breakthroughs in precision dynamic engagements against multiple maneuvering targets with selectable effects (hard kill, sensing, non-lethal), and those offering deep magazines, low cost per shot and “lowest” to zero collateral damage. This challenge includes research into fundamental understanding of laser sources, adaptive optics compensation techniques, long range atmospheric propagation physics, and the characterization of laser-matter interactions. This program will develop scientific understanding, components and subsystems to enable a USPL-based DEW best suited for naval applications.
