Raytheon Integrated Defense Systems has been awarded a task order valued $314m for the Patriot Integrated Air and Missile Defense System.

It is the third annual indefinite-delivery, indefinite-quantity (IDIQ) order out of a total of five such awards.

The task order for engineering services was awarded by the US Army and is funded by 17 nations that depend on the missile defence system.

The nations are the US, the Netherlands, Germany, Japan, Israel, Saudi Arabia, Kuwait, Taiwan, Greece, Spain, the Republic of Korea, the UAE, Qatar, Romania, Sweden, Poland and Bahrain.

The Patriot weapon system is being enhanced to be able to counter evolving threats.

Under the contract, Raytheon is responsible for delivering software and hardware development, configuration management, integration and test services and logistics support.

Additionally, the company will add several project results into Patriot Post Deployment Build 8.1. This will include methods to search, detect, track, discriminate, engage, and defeat a range of missiles and aircraft.

Raytheon Integrated Defense Systems business Integrated Air and Missile Defense vice-president Tom Laliberty said: “These modernisation efforts ensure Patriot continues to outpace the advancing and proliferating threat, and will be ready when needed.

“The 17-nation Patriot partnership shares the cost and reaps the benefit of continued investment in the system.”

As part of the contract, Raytheon will also integrate the Warfighter Machine Interface (WMI) into the system to provide 3D visuals of the battlespace and search functions.

To make the system more reliable, Raytheon will enhance Patriot’s resilience against cyber threats and increase its mission readiness. The company will also work towards lowering life cycle costs of the system.

In February this year, Greece planned to deploy Patriot missile system in Saudi Arabia as part of a programme. The programme also included the US, the UK and France.
