- L-3 ProVision millimeter wave body screening portal increases
             security while protecting passenger privacy -

NEW YORK--(BUSINESS WIRE)--Oct. 11, 2007--L-3 Communications (NYSE: LLL) announced today that the Transportation Security Administration (TSA) has begun testing its L-3 ProVision millimeter wave (MMW) body screening portals at Phoenix Sky Harbor Airport (PHX). The portals will be offered as a voluntary alternative to a pat-down secondary screening. TSA plans to test these technologies further at New York's JFK and LAX in Los Angeles in the coming months.

"We are pleased that TSA has chosen to test our L-3 ProVision millimeter wave technology as a potential alternative to the physical pat-down that is currently used in most airports. L-3's non-X-ray-based screening technology is fast and effective and has the potential to strengthen security at the nation's transportation hubs, while protecting passengers' privacy," said Craig Coy, President of L-3's Homeland Security Group.

L-3's millimeter wave technology pinpoints objects made of any material, including liquids, rubber, wire, plastic, and metal, to quickly and easily locate weapons, contraband, and other threats concealed under an individual's clothing. The portals detect concealed and hidden objects such as metallic and non-metallic weapons and virtually all known explosives, and other contraband in seconds.

"With the addition of our advanced checkpoint MMW portals to L-3's high-energy X-ray air cargo inspection systems and automated explosives detection systems for baggage screening, we can provide a full range of cutting edge aviation security technology. L-3 is proud to continue our work with TSA on its very important mission," said Thomas Ripp, President of L-3 Security and Detection Systems.

L-3 ProVision MMW portals are presently used for Israel's new advanced border crossing, at Amsterdam Schiphol Airport, Madrid Barajas International Airport, control checkpoints in Iraq's International Zone (Green Zone), facilities in Afghanistan as part of the NATO contingent, and a data center in Tokyo. This technology is also being evaluated at Mexico City International Airport, ferry landings in Singapore, railway and transit stations in London and New York, and at government and commercial buildings in The Netherlands - including the Rotterdam Courthouse. Additionally, the system is currently installed and under evaluation at the District of Colombia's Federal Courthouse, the El Paso County Terry R. Harris Judicial Complex in Colorado Springs, Colorado, and other government facilities.

With a broad range of systems and technology, and an installed base of more than 18,000 systems worldwide, L-3 Security and Detection Systems offers screening technologies for numerous security applications that include: (1) aviation systems for checked baggage explosives detection, oversized baggage, and checkpoint screening; (2) cargo and air freight screening; (3) port and border inspection; and (4) facility protection.
