Air Force scientists are working to arm the B-52 with defensive laser weapons able to incinerate attacking air-to-air or air-to-ground missile attack. Offensive and defensive laser weapons for Air Force fighter jets and large cargo aircraft have been in development for several years now. However, the Air Force Research Lab has recently embarked upon a special five-year effort, called the SHIELD program, aimed at creating sufficient on-board power, optics and high-energy lasers able to defend large platforms such as a B-52 bomber.
