Northrop Protests Contract Award to Rival: Century City-based Northrop Grumman Corp. has asked the General Accounting Office to revoke a $619.9-million contract won by Raytheon Co. for airport radar systems. “We do not understand the basis for the selection, given that the government reported we met or exceeded all requirements for the system,” said Russ Bahner, a vice president with Northrop Grumman’s Electronic Sensors and Systems division. Last week, Raytheon said it won the contract to provide the radar systems for civilian and military airports around the country. The contract is being managed by the Air Force and the Federal Aviation Administration. The congressional investigative agency will review the data used to select Lexington, Mass.-based Raytheon as the supplier for up to 213 Digital Airport Surveillance Radar systems by 2007. Raytheon executives declined to comment on Northrop’s protest.
