L-3 Communications Telemetry-West to Provide 125 Sets of
Additional Telemetry Hardware for Boeing’s JDAM Program

August 10, 2004

SAN DIEGO, CA, August 10, 2004 — L-3 Communications Telemetry-West (L-3 Telemetry-West), a division of L-3 Communications Corporation (NYSE: LLL), announced today that it has been awarded a contract by The Boeing Company (NYSE: BA) for 125 additional sets of compact telemetry (CTM) kits in support of Joint Direct Attack Munition (JDAM) Lot 8 production. Each CTM kit includes a PCM encoder, an S-band transmitter and harnessing — all configured as an integral telemetry subsystem. The CTM kit is installed in a JDAM tail kit, either in the factory or in the field, and provides telemetry during flight test. All hardware will be delivered in 2004 and 2005.

JDAM continues to be a highly successful, low-cost guidance kit that converts existing unguided free-fall bombs into accurately guided “smart” weapons. By adding a JDAM tail section to existing inventories of MK-82, MK-83, MK-84, BLU-110 and BLU-109 bombs, JDAM provides highly accurate weapon delivery in any “flyable” weather. JDAM can be dropped up to 15 miles from a target and receives updates from GPS satellites to help guide the bomb to the target.

“Over the past nine years, L-3 Telemetry-West has delivered approximately 1,000 sets of telemetry equipment to Boeing on the JDAM program and many of its derivatives,” said Dick Perry, director of airborne business development for L-3 Telemetry-West. “We are proud to be a continuing contributor on JDAM, especially as it relates to our role as an integral part of the flight test portion of the program.”

L-3 Telemetry-West currently provides PCM300 telemetry encoders and CTM-905 synthesized 5-watt S-band transmitters as part of the CTM kit for the JDAM program. The PCM300 provides data acquisition from various analog and discrete sensors as well as the onboard guidance computer. The PCM300 encoder is highly flexible and fully programmable, and due to its small size is an excellent fit for the JDAM tail kit. The CTM-905 transmitter is a miniaturized unit that provides for transmission of the telemetry data to a ground station. The CTM kit was developed specifically for the smaller MK-82 configurations and is now used in all JDAM test kits. L-3’s CTM kit and, prior to its introduction, the PCM600 encoder and CSS-905 transmitter, have been successfully used on all previous JDAM test flights.
