WASHINGTON (AP) - The Federal Aviation Administration on Friday said three defense companies have qualified to compete in one portion of a multibillion-dollar contract to upgrade the nation's air traffic control system.
The three companies qualified to compete are Bethesda, Md.-based Lockheed Martin Corp., White Plains, N.Y.-based ITT Corp. and Waltham, Mass.-based Raytheon Co.
The company that wins the contract will build a Global Positioning System for commercial and general aviation aircraft. The goal is to reduce runway mix-ups and increase the number of planes that can safely be aloft at one time.
