Air Force Research Lab’s Directed Energy Directorate at Kirtland AFB, N.M., in concert with Boeing, has demonstrated that a dual-mirror system can redirect a laser to a target, extending the laser’s range. Using a prototype called the Aerospace Relay Mirror System, researchers successfully tested a non-lethal laser beam by firing it a one of two mirrors from several miles away and then using the second mirror to relay the beam to a ground-based target another two miles away. In this test, a crane hoisted the two mirrors up about 100 feet. In a real application, a high-altitude airship could loft the mirrors to some 70,000 feet, where there would be little atmospheric turbulence to affect beam quality.
The Air Force is spending heavily on F-22 improvements through the end of the decade, suggesting it may not retire the jet in 2030 as it previously planned. New sensors, fuel tanks, communications, and electronic warfare systems are among the upgrades that comprise the package.
