Patriot
The Patriot is a mobile, long-range air defense system used by the U.S. Army and allied nations to shoot down enemy aircraft, cruise missiles, and ballistic missiles. It serves as a critical component of layered air and missile defense.

TECHNICAL DEFINITION
The MIM-104 Patriot, developed by Raytheon, is a long-range, all-altitude, all-weather surface-to-air missile (SAM) system used for theater air and missile defense (AMD). It employs advanced phased-array radar (AN/MPQ-53/65) and interceptors like the PAC-2 and PAC-3 to engage and destroy tactical ballistic missiles (TBMs), cruise missiles, and advanced aircraft.
BACKGROUND
The MIM-104 Patriot is a mobile interceptor missile surface-to-air missile (SAM) system, the primary such system used by the United States Army and several allied states. It is manufactured by the U.S. defense contractor Raytheon and derives its name from the radar component of the weapon system. The AN/MPQ-53 at the heart of the system is known as the "Phased Array Tracking Radar to Intercept on Target", which is a backronym for "Patriot". In 1984, the Patriot system began to replace the Nike Hercules system as the U.S. Army's primary high to medium air defense (HIMAD) system and the MIM-23 Hawk system as the U.S. Army's medium tactical air defense system. In addition to defending against aircraft, Patriot is the U.S. Army's primary terminal-phase anti-ballistic missile (ABM) system. As of 2016, the system is expected to stay fielded until at least 2040.
