The U.S. Air Force Research Laboratory has authorized Raytheon Company to demonstrate target recognition technology designed to increase protection for ground forces without compounding risk to an aircraft stalking enemies who threaten those forces.

First in a laboratory and then aloft, the company expects to show how its Air-to-Ground Radar Imaging II program would permit aircraft at a safe distance to detect, track and target hostile forces in motion on the ground.

The laboratory demonstration is expected in autumn 2008, followed by a flight next spring aboard a Raytheon test aircraft.

A new type of flying machine is watching you Onera JUST below a half-opened garage door a tiny device can be seen at the feet of someone lurking in the shadows. It looks like a blue dragonfly. Then its miniature wings begin to flap as it slips under the door and darts along the street. After rising through the air it stops to hover outside the window of a building several storeys high. There is an opening on the roof, and it slips inside. As it flits from room to room its video-camera “eye” transmits pictures to a screen on a remote-control unit strapped to the wrist of its clandestine operator. This is not a scene from a James Bond film, in which 007 tests a new device from “Q”, but an animated video produced by Onera, France’s national aerospace centre, to explain REMANTA, a project to develop the technologies needed for miniature robotic aircraft. More bug-like flying devices are being developed in other research laboratories around the world. A few are already small enough to be carried in a briefcase; others are the size of a jet fighter and need a runway for take-off.

Having evolved from military use, drones, or unmanned aerial vehicles (UAVs), are taking to the air in increasing numbers for public-service and civilian roles. They are being operated by groups as diverse as police, surveyors and archaeologists. A UAV helped firemen track the blaze that recently ravaged southern California. The most immediate advantage of a UAV is cost: operating even a small helicopter can cost $1,000 an hour or more, but the bill for a drone is a fraction of that. However, the growing use of UAVs is causing a number of concerns.

The first is safety. Last month America’s National Transportation Safety Board (NTSB) completed its first-ever investigation into an unmanned-aircraft accident. Pilot error was blamed for the crash in Arizona in April 2006 of a 4,500kg (10,000lb) Predator B, a type of UAV used by American forces in Iraq and Afghanistan. It was being operated by Customs and Border Protection when its engine was accidentally turned off by the team piloting it from a control room at an army base. No one was hurt, but the NTSB issued 22 recommendations to address what Mark Rosenker, its chairman, described as “a wide range of safety issues involving the civilian use of unmanned aircraft.”

Redondo Beach, CA — Northrop Grumman Corporation has achieved two milestones that helped prepare the U.S. Missile Defense Agency’s (MDA) Airborne Laser (ABL) aircraft for integration of the Northrop Grumman-developed high-energy laser. Both accomplishments contributed to MDA’s success in meeting its fifth and final “Knowledge Point” or milestone for 2007 covering high-power systems integration readiness, continuing recent program progress.

Northrop Grumman’s Space Technology sector completed inspection and refurbishment of the components and parts that compose the Chemical Oxygen Iodine Laser (COIL), a megawatt-class laser the company designed and built for the ABL program. In conjunction with The Boeing Company (NYSE:BA), ABL’s prime contractor, Northrop Grumman also completed extensive engineering drawings for the installation of the laser. The drawings incorporate streamlined processes and other improvements learned during ground tests concluded in 2005.

“These achievements represent outstanding progress toward providing our nation with a mobile, speed-of-light capability to attack ballistic missiles during their boost phase,” said Alexis Livanos, corporate vice president and president of the company’s Space Technology sector.
