L-3 Communications Awarded $27.7 Million Contract to
Supply Traveling Wave Tubes for U.S. Air Force Radar Systems

New York, NY, December 17, 2003 -- L-3 Communications (NYSE: LLL) announced today that its Electron Devices division (L-3 Electron Devices) has been awarded a $27.7 million contract from the U.S. Air Force's Ogden, Utah, Logistics Center to supply Traveling Wave Tubes (TWTs) for high-power surveillance radar systems. The contract is a five-year requirements contract to supply all TWTs used in the AN/FPQ-16 Perimeter Acquisition Radar Attack Characterization System (PARCS) and the AN/FPS-108 Cobra Dane Radar system. L-3 Electron Devices expects system deliveries to begin in 2004 and run through 2009.

“Our TWT technology plays an important role in ensuring that the U.S. Air Force can continue to perform a vital mission that is not only key to our country’s defense, but to the safety of our manned space flight and satellite projects,” said Jim Benham, president of L-3 Electron Devices. “We are honored to have been selected by the U.S. Air Force to support its critical radar systems and we look forward to a successful partnership over the next five years.”

The AN/FPQ-16 PARCS is an outgrowth of the Safeguard Anti-Ballistic Missile system at Cavalier Air Force Station, North Dakota, 90-miles north of Grand Forks Air Force Base in the northeastern corner of North Dakota. The PARCS radar is the largest phased-array radar system in the world. The Air Force assigned the radar the primary mission of warning/attack assessment of Submarine Launched Ballistic Missile (SLBM) and Intercontinental Ballistic Missile (ICBM) attack against the continental United States and southern Canada. The radar is so precise, it can identify objects the size of a basketball at a range of 2,000 miles. Its secondary mission is to track space debris that could interfere with shuttle missions as well as satellites.

The Cobra Dane system provides 120-degree radar coverage of a 2,000-mile corridor that spans the eastern Russian peninsula and northern Pacific Ocean. Its digital data and voice communication systems interface with the National Air Intelligence Center and the North American Aerospace Defense Command. The Cobra Dane collects exoatmospheric, multiple-object intelligence data on Russian re-entry vehicles and can extract and reduce data on site. The system also provides early warning and attack assessment for missiles that would impact the continental United States, and detects and catalogs satellites for the U.S. Air Force’s spacetrack systems.
