The US Navy has contracted Lockheed Martin to continue to support Radiant Mercury, a cross-domain intelligence sharing system that allows secure sharing of sensitive data between unclassified and classified security domains.

Valued at $90m, the two contracts include support for Radiant Mercury over the next five years.

Lockheed Martin Information Systems and Global Solutions business C4ISR vice-president Dr Rob Smith said: "Since developing Radiant Mercury in 1992, we’ve ensured it has met the operational needs of customers throughout the world.

"Radiant Mercury has been designed to protect classified data from unauthorised access."

"As we deploy the fourth generation of the system, we’ll continue to advance it with the most robust capabilities available."

Radiant Mercury has been designed to protect classified data from unauthorised access, especially when it is transferring from one network domain to another.

While the sharing of sensitive and critical information is put through high levels of scrutiny, the system allows military and intelligence users with the appropriate security classification to retrieve the required data.

Capable of supporting simultaneous data flows to hundreds of channels and interfaces with most major C4ISR systems, Radiant Mercury is compliant with the Intelligence Community Directive 503 policy and is also approved for both top secret and secret interoperability by the Unified Cross Domain Services Management Office.

It is used by both US and allied partners at more than 400 sites worldwide, and is available on the US General Services Administration schedule of products and services.
