Northrop Grumman Loses Contract Dispute: The Los Angeles-based aerospace concern lost its protest of a $398-million Navy award for computer systems that went to Intergraph Corp. of Huntsville, Ala., Intergraph said. The U.S. General Service Administration’s Board of Contract Appeals upheld Intergraph’s selection for the 12-year contract awarded in July. The deal calls for Intergraph to provide computer systems and related equipment used in such programs as electronic warfare and underwater surveillance, Intergraph said. Northrop Grumman declined to comment, saying it had yet to see the decision.
