The AN/TWQ-1 Avenger Air Defense System is an American self-propelled surface-to-air missile system which provides mobile, short-range air defense protection for ground units against cruise missiles, unmanned aerial vehicles, low-flying fixed-wing aircraft, and helicopters.
The Avenger was originally developed for the United States Armed Forces and is currently used by the U.S. Army and was also used by the U.S. Marine Corps.
In accordance with the Joint Electronics Type Designation System (JETDS), the "AN/TWQ-1" designation represents the first design of an Army-Navy electronic device for ground transportable armament special combination equipment. The JETDS system also now is used to name all Department of Defense electronic systems.
