The U.S. Air Force awarded Raytheon Co. a $14 million Lot 2 contract to continue full rate production of High-Speed Anti-Radiation Missile (HARM) Control Section Modification (HCSM) upgrade units.

The modification adds a GPS receiver and an improved inertial measurement unit (IMU) for precision navigation to the existing HARM. HCSM also features a digital flight computer that merges targeting solutions from navigation and seeker systems.

"HCSM upgrades to the HARM allow the enhanced weapon to precisely engage the target set," saidJack Roosa, HARM program director for Raytheon Missile Systems. "These upgrades negate many counter tactics of sophisticated radar-directed defenses and add a stand-off, high-speed strike capability against time critical targets of known location."

Raytheon began modification of existing HARMs early this year. Delivery of HCSM units is scheduled for the fourth quarter of 2013. Raytheon has teamed with Honeywell, Rockwell Collinsand others for the HCSM program.

The contract was awarded in Raytheon's second quarter of 2013.

About HARM and HCSM

The AGM-88 High-Speed Anti-Radiation Missile is a key battlespace element to suppress or destroy surface-to-air missile radars, early warning radars and radar-directed air defense artillery systems. HARMs have made hostile airspaces worldwide safer for U.S. and allied warfighters. The missile resides in the inventories of eight countries.

  • More than 4,000 HARMs have been employed in combat.
  • HCSM adds GPS/IMU navigation accuracy, giving HARM the ability to engage time-critical targets.
  • HCSM has new features that degrade counter-HARM tactics, while reducing the risk of fratricide or collateral damage.
