Patriot/Medium Extended Air Defense System Combined Aggregate Program

The Patriot/Medium Extended Air Defense System Combined Aggregate Program (Patriot/MEADS CAP) is a Major Defense Acquisition Program managed by the Department of Defense under Acquisition Category ID. This surface-to-air missile defense program operates within the Major Capability Acquisition pathway and represents a significant investment in military air defense capabilities. The program encompasses the procurement and sustainment of missile systems, associated radar and control equipment, training systems, and supporting components essential for air defense operations.

Contract awards under this program range from small purchases of specialized cable assemblies ($2,454) to major system modifications ($70.9 million), with typical performance periods of 6-24 months. Primary contractors include Raytheon Company's Land & Air Defense Systems division, which serves as the key provider of PATRIOT system components and modifications. Other significant contractors include Mercury Systems, Microsemi Corporation, and Marvin Engineering Co. Most awards are issued by the U.S. Army Materiel Command Aviation and Missile Life Cycle Management Command, with contracts primarily structured as firm-fixed-price arrangements through definitive contracts, delivery orders, or purchase orders. While some smaller components are procured through small business set-asides, the majority of significant system deliveries and modifications are unrestricted awards. Common deliverables include circuit card assemblies, cable assemblies, radar components, power supplies, training systems, and specialized electronic components, with primary places of performance including Raytheon's facilities and various contractor locations across the United States.
