BAE Systems has been awarded a seven-year £47 million contract by the Ministry of Defence to provide support for the Combat Management System (CMS) on the Royal Navy's Type 23 frigates and Royal Fleet Auxiliary (RFA) Argus.

The CMS assists a ship's command in detecting and countering threats to the ship and any surrounding forces by managing all relevant external and internal information provided by the ship's radars. It integrates this information with the activities of the anti-air weapons systems as well as other sensors and weapons.

This latest contract is part of a larger framework deal called the Joint Support Solution (JSS) contract, which was awarded to BAE Systems in September 2009. The JSS provides a common support framework for the CMS on Type 45 destroyers, Type 23 frigates and RFA Argus.

JSS is designed to provide software support, along with spares and repairs, using commercial IT equipment in an operational environment.

Dave Twitchin, head of maritime combat systems at the MoD's Defence Equipment & Support organisation, said, "This was far from a straight forward piece of work and is the result of innovative thinking and months of sheer hard graft.

"The result is clear evidence of the benefits that can be delivered by working together to achieve a single shared objective of delivering front line capability at reduced cost and improved quality."

The JSS is being delivered by BAE Systems employees in New Malden, Dorchester, Frimley and Portsmouth.

The main Royal Navy website had to be taken down last year after being hacked. A Romanian hacker claimed responsibility for the attack.
