Thanks to an Airborne Laser system by Lockheed Martin, modified 747-400F's are now equipped to take out enemy missles. This system consists of a "High Energy Laser", "Flight Turret Assembly", "Tracker Illuminator lasers", and a "Beacon Illuminator". We may soon see this technology on other aircraft such as the B2 Stealth Bomber. More pics after the jump.
