Patriot missiles are mainly made by Lockheed Martin , while Raytheon is the main company behind the Patriot air-defense system itself and its integration. In practice, the Patriot program is a team effort, with Lockheed Martin producing the PAC-3 interceptor missiles and Raytheon handling major system components like radar and launch systems.
