NEW YORK, NY, May 27, 2003 - L-3 Communications (NYSE: LLL) today announced that its Link Simulation and Training division has been awarded a $22.07 million delivery order to develop concurrency upgrades on aircrew and maintenance training systems for the U.S. Air Force's B-2A Spirit training program.

Upgrades to the B-2A training system, which will be performed by Link's Binghamton, NY and Arlington, TX operations, will focus on concurrency modifications to the training system and a computer upgrade for the aircrew trainers

A primary modification Link will make to the trainers -- which includes three weapon system trainers, one mission trainer, a suite of maintenance trainers and a weapons load trainer -- will focus on simulating the aircraft's new LINK-16 Center Instrument Display/In-flight Replanning system. The LINK-16 Center Instrument Display/In-flight Replanning system provides technical and operational improvements to the B-2A's tactical data link capabilities.

"This award continues Link's ongoing total system support of the U.S. Air Force's B-2A training program," said David Williams, Link's vice president of Training Services Programs. "Since the mid-1980s, we have continued to work closely with both the Air Force and Northrop Grumman, the B-2A weapon system developer, in the modernization of the B-2A weapon system."

This delivery order is part of a trainer modification plan identified in the B-2A Training System Contractor Logistic Support contract awarded to Link in 1998. This indefinite delivery/indefinite quantity contract spans 10 years, and calls for Link to provide all contractor supplied services and product updates for the B-2A training system. These modifications are part of an ongoing effort to upgrade the training system to maintain concurrency with the B-2A weapon system.

The B-2A training system has been fielded at Whiteman Air Force Base, MO since the early 1990s. This system supports initial and continuation aircrew and maintainer training in addition to providing rehearsal training for actual combat missions flown by B-2A pilots of the 509th Bomb Wing.

The B-2A weapon system trainer is a full-motion, high fidelity trainer providing out-the-window visual scenes and simulation of all onboard systems. The weapon system trainer allows B-2A pilots to become proficient in operating the aircraft and its weapon systems under simulated combat situations that can take place in virtually any part of the world.

B-2A pilots use the mission trainer, which provides the same level of high fidelity simulation found on the weapon system trainer, to perfect their skills in operating the aircraft's onboard systems.

The B-2A maintenance training system is composed of a suite of trainers used by B-2A maintainers, pilots and weapon load technicians to gain off-aircraft expertise in the diagnosis and repair of aircraft systems and the loading of weapons.

This effort is part of an overall training system modification that will provide training device and curriculum updates to support the B-2A Flexible Acquisition and Sustainment Team (FAST) aircraft upgrade program.
