The Lockheed Martin Corp. Tactical Defense Systems division in Eagan, Minn., and Aeronautical Systems division in Marietta, Ga., are equipping one U.S. Navy P-3 four-engine turboprop maritime patrol aircraft with the Cooperative Engagement Capability (CEC), which can share radar information from several different sensors and hand the information off to any CEC-equipped aircraft, ship, or submarine. The CEC-equipped P-3 will have systems similar to those installed on a U.S. Customs Service P-3 radar aircraft. - J.K.
