We are only a few years away from the sky War of the directional energy weapon. The U.S. Air Force Research Laboratory and Lockheed Martin signed a contract worth 26.3 million, requiring it to test high energy laser systems on tactical fighters by 2021. Lockheed will develop an advanced version of the multi-kilowatt fiber laser. It has developed 30-kilowatt lasers that combine 100 of lasers, and this year has delivered a 60-kilowatt version to the U.S. Army for testing on military towed trailers. The contract for the Air Force Research Laboratory is part of the SHiELD (Self-protect High Energy Laser Demonstrator) project designed to test fighter aircraft’s ability to use lasers to defend against ground or aerial missiles. In addition to Loma, Grumman is developing a beam-control system to target fire, and Boeing is integrating lasers into the outer pod. The general Atom developed a compact non-fiber laser hellads.
