EDO AWARDED $2.5 MILLION SONAR CONTRACT

NEW YORK - December 9, 2004 - EDO Corporation (NYSE: EDO) has been awarded a $2.5 million contract from Lockheed Martin (NYSE: LMT) for continued production of subassemblies for the TB-29A thin-line towed-array sonar system.

Towed arrays are acoustic sensors attached by tow cables to surface ships and submarines, enabling them to detect sounds emitted by other vessels. In this follow-on contract, EDO will manufacture thousands of piezoelectric ceramic cylinders, hydrophones, and micro-circuits, and then integrate them into dual acoustic-channel assemblies.

"EDO has been producing advanced sonar technology since the 1940s," said James M. Smith, EDO’s chief executive officer. "Since the early 1990's, we have supplied Lockheed Martin and the Navy with sensor technology and hardware in support of the TB-29A program. This contract shows the continued high confidence and trust that Lockheed Martin and the Navy have in EDO as a first-tier supplier of sensors for mission critical sonar systems."

EDO Corporation provides sonar equipment for anti-submarine and mine warfare, as well as underwater navigation and communication sonar for surface ships and submarines. Other business areas include a diverse range of products for the defense industry and commercial markets, and related engineering and professional services.

Major product groups include: Aircraft Armament, Defense Electronics, Communications, Undersea Warfare, and Integrated Structures. EDO’s advanced systems are at the core of the transformation to lighter, faster, and smarter defense capabilities.

EDO was founded in 1925 and is headquartered in New York City. The company had revenues last year of $461 million and employs 2,700 people.
