Last year, in conversation with Popular Science, Lockheed's Chief Technology Officer said of an airborne laser weapon: "It's game changing. Should you develop an operational weapon that operates at Mach a million, that's game changing." This turret is part of that package. The program, funded by DARPA and the Air Force Research Laboratory, is called "Aero-adaptive Aero-optic Beam Control", and it's been in the works for some time. One promise of the technology: defending larger airplanes, much like machine gun turrets protected bombers in World War II. Only this time, instead of shooting down fighter jets, the lasers could also stop missiles and drones.
