HARM is an anti-radiation, air-to-surface missile highly effective against enemy ground radar.
AGM-88 is a joint USAF-Navy weapon, carried by SEAD-dedicated F-16CJs. AGM-88B is equipped with erasable and electronically programmable read-only memory, permitting in-field changes to missile memory. The AGM-88C is the current production model with a more lethal warhead.
Raytheon began a HARM Control Section Mod (HCSM) in 2013 to convert current models to more precise AGM-88Fs incorporating improved GPS/INS guidance, anti-countermeasure performance, and reduced risk of collateral damage.
The Navy is further retrofitting its missiles with advanced networking, digital homing, and terminal millimeter-wave radar seeker resulting in the AGM-88G Advanced Anti-Radiation Guided Missile (AARGM).
USAF is pursuing the extended-range AARGM-ER as the basis for its next-generation Stand-in Attack Weapon (SiAW) to equip the F-35A with SEAD capability. The missile will additionally enable it to strike advanced threats including theater ballistic missile and land attack/anti-ship missile sites, GPS jammers, and anti-satellite systems.
USAF aims to complete integration and fielding of SiAW on the F-35 by the mid-2020s.
