The High-Speed Anti-Radiation Missile Control Modification adds a GPS receiver and an improved inertial measurement unit for more precise navigation. 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," said Jack 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 said it started modification of existing HARMs earlier this year.
Delivery of HCSM units will occur before the end of the year.
HARM missiles are used to suppress or destroy enemy surface-to-air missile radars, early warning radars and radar-directed air defense artillery systems.
