Patriot is a long-range, all-altitude, all-weather air defence system to counter tactical ballistic missiles, cruise missiles and advanced aircraft. Patriot (MIM-104) is produced by Raytheon in Massachusetts and Lockheed Martin Missiles and Fire Control in Florida.

As well as the USA, Patriot is in service in Egypt, Germany, Greece, Israel, Japan, Kuwait, the Netherlands, Saudi Arabia and Taiwan.

Patriot missile systems were deployed by US forces during Operation Iraqi Freedom. The systems were stationed in Kuwait and successfully destroyed a number of hostile surface-to-surface missiles using the new PAC-3 and guidance enhanced missiles.
