The AGM-88 High-speed Anti-Radiation Missile (HARM) is a tactical, air-to-surface missile designed to home in on electronic transmissions coming from surface-to-air radar systems. It was originally developed by Texas Instruments as a replacement for the AGM-45 Shrike and AGM-78 Standard ARM system. Production was later taken over by Raytheon Corporation when it purchased the defense production business of Texas Instruments.

The AGM-88 can detect, attack and destroy a radar antenna or transmitter with minimal aircrew input. The proportional guidance system that hones in on enemy radar emissions has a fixed antenna and seeker head in the missile's nose. A smokeless, solid-propellant, booster-sustainer rocket motor propels the missile at speeds over Mach 2. HARM, a U.S. Navy-led program, was initially integrated onto the A-6E, A-7 and F/A-18 and later onto the EA-6B. RDT&E for use on the F-14 was begun, but not completed. The USAF introduced HARM on the F-4G Wild Weasel and later on specialized F-16s equipped with the HARM Targeting System (HTS).

The HARM missile was approved for full production in March 1983, obtained initial operating capability (IOC) on the A-7E Corsair II in late 1983 and then deployed in late 1985 with VA-46 aboard the aircraft carrier USS America. In 1986 the first successful firing of the HARM from an EA-6B was performed by VAQ-131. It was soon used in combat—in March 1986 against a Libyan SA-5 site in the Gulf of Sidra, and then Operation Eldorado Canyon in April. HARM was used extensively by the United States Navy and the United States Air Force for Operation Desert Storm during the Gulf War of 1991.
