A supersonic Lockheed Martin (NYSE:LMT – News) F-35B Lightning II stealth fighter rode more than 41,000 pounds of thrust to a vertical landing today for the first time, confirming its required ability to land in confined areas both ashore and afloat.
“Today’s vertical landing onto a 95-foot square pad showed that we have the thrust and the control to maneuver accurately both in free air and in the descent through ground effect,” said F-35 Lead STOVL Pilot Graham Tomlinson.
Tomlinson performed an 80-knot (93 miles per hour) short takeoff from Naval Air Station Patuxent River, Md., at 1:09 p.m. EDT. About 13 minutes into the flight, he positioned the aircraft 150 feet above the airfield, where he commanded the F-35 to hover for approximately one minute then descend to the runway.
“The low workload in the cockpit contrasted sharply with legacy short takeoff/vertical landing (STOVL) platforms,” said Tomlinson, a retired Royal Air Force fighter pilot and a BAE Systems employee since 1986. “Together with the work already completed for slow-speed handling and landings, this provides a robust platform to expand the fleet’s STOVL capabilities.”

Within seconds, the ALTB used onboard sensors to detect the boosting missile and used a low-energy laser to track the target. The ALTB then fired a second low-energy laser to measure and compensate for atmospheric disturbance. Finally, the ALTB fired its megawatt-class High Energy Laser, heating the boosting ballistic missile to critical structural failure. The entire engagement occurred within two minutes of the target missile launch, while its rocket motors were still thrusting.

Airborne Laser Testbed (ALTB) The Airborne Laser Testbed (ALTB) is being developed as an advanced platform for mdas directed energy research program. Using two solid state lasers and a megawatt-class Chemical Oxygen Iodine Laser housed aboard a modified Boeing 747-400 Freighter, the ALTB uses directed energy to demonstrate the potential of using directed energy as a viable technology against ballistic missiles. Firing Sequence The Airborne Laser Testbed uses six infrared sensors to detect the exhaust plume of a boosting missile. Once a target is detected, a kilowatt-class solid state laser, the Track Illuminator, tracks the missile and determines a precise aim point. The Beacon Illuminator, a second kilowatt-class solid state laser, then measures disturbances in the atmosphere, which are corrected by the adaptive optics system to accurately point and focus the high energy laser at its intended target. Using a very large telescope located in the nose turret, the beam control/fire control system focuses the megawatt-class COIL beam onto a pressurized area of the boosting missile, holding it there until the concentrated energy compromises the structural integrity of the threat missile causing it to fail.
