Description: The expansion of the detailed plan for assessing and demonstrating the complementary nature of High Energy Laser (HEL) weapons, coupled with defensive missiles for ship self-defense, will be accomplished with this funding. Critical tests required are full-scale static tests using an existing HEL to demonstrate charring on actual anti-ship missiles. Preparing for these tests requires preparation of detailed system test requirements and concept definition work. The engineering analysis, accomplished by this effort, will ensure the technical feasibility of the testing and the expected results. The Naval High Energy Laser Weapon System (HELWS) Program, managed by NAVSEA PMS 405, is a research and development effort to develop a revolutionary ship self defense capability that meets both mid and far-term operational requirements. Due to Naval force reductions, and the change from 'blue water' to littoral operations, the survivability requirements for surface ships have in the last few years shifted from 'Mobility Survivability' to 'Mission Survivability' where no damage to the ship can be allowed. Some present, and most future, Anti-Ship Cruise Missiles (ASCMs) will engage the targeted ship while employing high-g maneuvers to minimize the effectiveness of the defensive weapon systems. A Naval HELWS offers the potential for complementing ship self-defense missile systems at ranges beyond where a HELWS-only catastrophic kill can occur, by increasing the defensive missile's effective probability of kill (Pk). Critical to demonstrating this capability are analyses associated with laser charring of composite radomes and the resultant decrease of the signal-to-noise ratio that would cause missile break lock to occur and the resultant change in effective Pk of the ASCM. Success of this effort is a vital portion of the overall plan to develop and field a Naval HELWS to meet future Navy operational requirements.
