The 17 user countries of Patriot air defense system are investing a total of app. €2.1 billion in a joint development of five tranches. The third tranche with a volume of €289 million has now been initiated by the U.S. Army on behalf of the user countries. Raytheon has been commissioned to provide comprehensive engineering services – including system, software and hardware development, integration and testing services – configuration management and logistical support.

The Patriot Post Deployment Build 8.1 project will incorporate a number of software and hardware capabilities. These include:

  1. New and advanced methods for searching, detecting, tracking, distinguishing, fighting, and defeating a wide range of evolving threats, including tactical ballistic missiles, cruise missiles, and fighter aircraft.
  2. Integration of the Warfighter-Machine Interface (WMI) command and control technology into Patriot. WMI provides an overview of the battlefield, including 3D visualizations, easy-to-read status pages and search functions.

Raytheon will also provide the following services under the contract:

  • Enhance Patriot’s resilience to evolving cyber threats.
  • Developing solutions to increase uptime and reduce life cycle costs by improving system reliability, and
  • Replacing obsolete components of Patriot’s communications system that allow Patriots to operate reliably until the U.S. Army’s new command and control system for integrated air and missile defense is operational.
