Raytheon (NYSE:RTN) has agreed to sell the Sultanate of Oman a ground-based air defense system worth $1.28 billion, the company announced Thursday.

The National Advanced Surface-to-Air Missile System (NASAMS), which Raytheon describes as "a highly adaptable mid-range... state-of-the-art defense system" equally capable of shooting down hostile aircraft, unmanned aerial vehicles, and missiles, is the same system that protects Washington, D.C. from air attacks. Finland, Norway, The Netherlands, Spain, and a fifth country (which prefers not to publicize its possession of the system), also use NASAMS for their national defense.

In addition to NASAMS per se, Raytheon says it is also providing Oman ground support equipment, a full training package, and technical assistance necessary to operate the system.
