Gulf sultanate of Oman is set to buy a $2.1 billion missile system built by the U.S. Raytheon Co. as part of a U.S. drive to install a coordinated air-defense system linking the region’s Arab monarchies to counter Iran.
Details of the contract, including the type of system involved, have not been disclosed, but Oman has been in the market for a medium-range surface-to-air missile system for some time.U.S. officials traveling with Kerry say the deal will enhance the air-defense systems the United States has sold to Saudi Arabia, the United Arab Emirates and other allies in the gulf.
