Romania has ordered Raytheon mode-S monopulse secondary surveillance radars for three of its airports as part of its upgrade to comply with European Union requirements for air traffic management. The U.S. company will supply Condor series 300 systems for en-route radar sites at Henri Coanda (Otopeni), Constanta and Arad international airports over the next 20 months, with the first system due to be installed at Otopeni airport in November.
