Raytheon has been awarded a new contract to upgrade the US Army Patriot air and missile defence systems.

The contract worth $115m awarded by the US Army Aviation and Missile Command will upgrade four additional US Army Patriot systems to configuration-3 status.

The upgrades involve enhancements to Patriot system ground components, particularly the radar.

Vice president and deputy for Patriot programmes at Raytheon Integrated Defence Systems (IDS) Joseph Garret said that the configuration-3 system provides the army with additional capability and flexibility to meet air defence requirements.

“Continuing pure fleet upgrades ensures our warfighters have the latest and best technology to meet evolving threats,” Garret said.

Raytheon IDS is the prime contractor for both domestic and international Patriot air and missile defence systems and systems integrator for Patriot advanced capability-3 missiles.
