HEL Hardening through Diffusely Reflective Coatings
Directed Energy Weapons are being rapidly developed to integrate into the warfighters arsenal. Equally important is the need for the ability to retroactively harden UAS platforms to keep in step with larger and more powerful DEWs. While there are a multitude of technologies available to harden assets, size, weight, performance and cost (SWaP-C) considerations must be considered. Further, the ability to retro-actively harden existing assets is highly desirable. The application of a diffusely reflective coatings that will reflect a significant portion of incoming laser energy before it reaches the substrate is of great interest to the Counter Directed Energy Weapon community. The Naval Research Laboratory has developed a diffusely reflective coating that has minimal SWaP-C penalties and can be retro-actively applied in field conditions. This coating has been applied to various platforms and has maintained adhesion at speeds approaching 1 Mach. Recent laser tests against aluminum and carbon fiber reinforced polymer targets, as well as advances to NRL Quick Fix White will be discussed.
