AFRL Simulates Air-to-Air Combat With Directed Energy Weapon Published Dec. 4, 2006 By Air Vehicles Directorate AFRL/VA WRIGHT-PATTERSON AIR FORCE BASE, Ohio -- In an effort to investigate the effect of a high-energy laser in air-to-air combat, AFRL is performing a Tactical High-Energy Laser Utility Study (THELUS) in a virtual simulation environment. As a follow-on to a previous test, AFRL scientists performed simulated tests of air-to-air engagement involving two aircraft versus four. For the test effort, six tactically rated pilots divided into two teams: red and blue. To acquire baseline data, the researchers first provided both teams with identical weapons and sensors; they later modified the blue team configuration to include the directed energy weapon (DEW), while the red team retained its conventional weaponry. In order to determine the DEW's effects on the mission, the researchers altered two distinct characteristics of the DEW throughout the test scenarios, changing the maximum sensor range (which determines how far pilots can see with the DEW) and the thermal budget (which determines how long pilots can fire continuously). The testing determined both survivability and mission success under the altered conditions. Pilots using the DEW were able to survive longer despite altered conditions. Furthermore, DEW utilization resulted in a greater probability of at least one pilot surviving the mission. An upcoming test will incorporate variable weather conditions to determine their effects on the DEW. Researchers will use these study results to highlight areas needing additional research and development; results will also assist in guiding future AFRL investment strategies.
