EDO EXPANDS ELECTRONIC-CONTROL PRODUCT LINE
WITH CONTRACT FROM GENERAL DYNAMICS

NEW YORK - April 21, 2004 - EDO Corporation (NYSE: EDO) has been awarded a development contract by General Dynamics Armament and Technical Products, a business unit of General Dynamics, (NYSE: GD) for an electronic-interface module to control the GAU-19/A weapon system.

The GAU-19/A is a three-barreled, 12.7mm electric Gatling Gun that provides high-rate-of-fire firepower in a small, lightweight weapon system. EDO has been selected as the primary supplier of the "Gun Interface Module" that electronically controls the weapon’s operation.

General Dynamics is the prime contractor selected to supply and test the GAU-19/A weapon system for the OH-58D "Kiowa Warrior" application, the Army’s primary armed observation helicopter. Successful development testing could lead to production of the GAU-19/A system for about 300 Kiowa Warrior aircraft in the Army’s inventory.

"This contract marks EDO’s entrance into a carefully targeted new market," said James M. Smith, EDO’s chief executive officer. "As an extension of our very successful aircraft armament control systems, it is a technology niche where we have substantial expertise. Our EDO MTech business unit is a leader in the design and development of electronic control systems, such as those incorporated into ‘smart’ weapon storage-and-release systems on the F-16 and F-18 fighter aircraft. We are pleased that our initiative to expand into related electronic-control systems is generating such promising initial results."
