Patriot Advanced Capability-3 Missile Segment Enhancement

The Patriot Advanced Capability-3 Missile Segment Enhancement (PAC-3 MSE) is a Major Defense Acquisition Program managed by the U.S. Army's Program Executive Office Missiles and Space. This Category IC program follows the Major Capability Acquisition pathway and focuses on developing, producing, and sustaining advanced missile defense capabilities. The program supports both United States military requirements and Foreign Military Sales customers through the delivery of enhanced missile systems, launch systems, and associated support services.

The program's contract awards primarily consist of cost-plus-fixed-fee and cost-plus-incentive delivery orders to Lockheed Martin Corporation, operating as Lockheed Martin Missiles and Fire Control, ranging from approximately $600,000 to $60 million with performance periods typically extending 24-26 months. These larger awards focus on missile support center services, logistics support, and launcher repair and return activities. Additionally, the program utilizes numerous smaller firm-fixed-price contracts and Blanket Purchase Agreement calls, typically under $50,000, for metal plating and treatment services at Letterkenny Army Depot. These smaller awards frequently employ total small business set-asides and are awarded to companies such as Celf Services LLC, Hard Chrome Specialists Inc., and Techmetals Inc. The U.S. Army Contracting Command at Redstone Arsenal serves as the primary contracting activity, with significant work performed in Grand Prairie, Texas and at Letterkenny Army Depot.
