ARLINGTON, VA, April 25, 2005 - United Defense Industries, Inc. (NYSE: UDI) announced today that United States Marine Repair (USMR), its ship repair and modernization subsidiary, has completed the acquisition of Corrosion Engineering Services, Inc. (CES) headquartered in San Diego, Calif. CES focuses primarily on corrosion control of U.S. Navy and commercial vessels.

"This acquisition allows USMR to grow our business by expanding into areas such as submarine work. DOD clearances are held by at least 75 percent of the painters at CES. Additionally, CES has surveyors and inspectors holding certification from the National Association of Corrosion Engineers and the U.S. Navy," said Al Krekich, president of USMR. "As CES and USMR have a major common customer in the U.S. Navy, this merging of services is of benefit to both companies and enables USMR to provide an even greater level of service to the military."

CES facilities are located in San Diego and Chula Vista, Calif.; Bremerton and Arlington, Wash.; Norfolk and Arlington, Va; Groton, Conn.; St. Mary’s, Ga.; Atlantic Beach, Fla.; and Pearl City and Aiea, Hawaii. CES employs 370 people.
