Raytheon has secured a $350m Federal Aviation Administration (FAA) contract modification to upgrade 135 air traffic control centres to the standard terminal automation system (STARS) configuration.
The implementation of STARS, which will run through to September 2017, will place the largest airports and almost 90% of all terminal airspace controlled by the FAA under the NextGen terminal automation platform.
The system has been implemented under FAA's terminal automation modernisation and replacement programme.
Raytheon Air Traffic Systems managing director Michael Espinola said: "STARS is now operating at 150 FAA and DoD terminal air traffic control facilities, and the performance of the system has been exceptional. STARS is the foundation for numerous NextGen efforts within the National Air Space."
The primary aim of the project is to maintain safety and ease pressure on the the increasingly congested NAS.
Both the FAA and the US Department of Defense (DoD) use STARS, which replaces several generations and versions of existing terminal automation systems. It also provides substantial savings in lifecycle costs.
The implementation of the system increases safety and includes additional capacity management features to terminal automation in the commercial and defence sectors.
Employing nearly 63,000 employees worldwide, Raytheon provides air traffic management technology, products and services to civil and military customers. Raytheon's ATM solutions operate in more than 60 countries and monitor more than 60% of the world's air space.
