Boeing received an $18 million contract from the U.S. Air Force to provide AN/APG-63(V) radars for Saudi Arabia's F-15SA aircraft.

The contract covers three of the radars, and follows the kingdom's recent commissioning of F-15SA fighter jets in January. The planes feature updated avionics, active electronically scanned array, or AESA, radars, and ASM-135 missiles.

According to the U.S. Department of Defense, work on the contract will take place in Forest, Miss., and is expected to be complete by March 2017.

The contract is comprised entirely of foreign military sales to Saudi Arabia. The Air Force Life Cycle Management Center at the Robins Air Force Base in Georgia is listed as the contracting activity.

The F-15SA is the Saudi variant of the Boeing-made F-15, a twin-engine tactical fighter initially developed for air supremacy missions. Currently, the plane is also fitted with ground attack capabilities.

Additional operators of the aircraft include Israel, Japan, Britain, Germany and the United States.
