The US Department of Defense is awarding Raytheon a $52.25 M contract modification for 19 APG-79 active electronically scanned array (AESA) radars to be retrofitted into F/A-18E/F aircraft, Lots 26-29. The APG-79 AESA radar, which will replace the APG-73 radar, will provide increased air-to-air detection and track range, increased air-to-ground targeting capabilities, longer launch range for standoff weapons, enhanced capability against advanced threats, and optimized utilization of the Super Hornet's weapons systems. The contract was awarded to Raytheon Space and Airborne Systems of El Segundo, CA. Work will be performed in Forest, MS (43 percent); Dallas, TX (29 percent); El Segundo, CA (27 percent); and Andover, MA (1 percent), and is expected to be completed in December 2013. Contract funds will not expire at the end of the current fiscal year. The Naval Air Systems Command, Patuxent River, MD, is the contracting activity. This award is a modification to a previously awarded firm-fixed-price contract (N00019-09-C-0003).
