The AGM-88 High-speed Anti-Radiation Missile (HARM) is an air-to-surface tactical missile designed to home in on electronic transmissions associated with surface-to-air missile radar systems. The missile was originally developed by Texas Instruments (TI) as a replacement for the AGM-45 Shrike and AGM-78 Standard ARM system. Production was later taken over by Raytheon Corporation (RAYCO) when TI's defense business was purchased by RAYCO.

Injury is damage or harm caused to the structure or function of the body caused by an outside or force, which may be physical or chemical. Injury may also refer to injured feelings or reputation rather than injuries to the body. A severe and perhaps life-threatening injury is called a physical trauma.
