The US Defense Information Systems Agency (DISA) has awarded Unisys a contract worth up to $214m to support the IT service optimisation, modernisation and consolidation strategy for defence agencies in the US and overseas.

Under the four-year deal, Unisys will provide secure global service desk and field service support for 19 of the Department of Defense’s fourth estate agencies.

The Fourth Estate includes the Missile Defense Agency, National Geospatial-Intelligence Agency and the DISA, which delivers IT support for military operations.

The information technology firm will deliver capabilities of its InteliServe platform of service desk managed services. It will also work with DISA to decrease the cost of duplicative common-use IT environments and to help increase cyber readiness.

Using a shared support infrastructure, Unisys service agents will investigate and resolve IT incidents, as well as service requests from DISA mission partners across the globe.

The company will serve DISA headquarters in Fort Meade in Maryland, Scott Air Force Base in Illinois, and DISA offices in Germany and Bahrain.

Unisys Federal group vice-president for defence and intelligence agencies Andrew Boyd said: “Under this new contract with DISA, Unisys will leverage its experience helping private sector clients, as well as government clients like the army, apply innovative concepts like artificial intelligence and machine learning to service desk and field support operations.

“With this award, we are poised to bring new, best-in-class services to the Department of Defense with the same quality and efficiency Unisys offers to Fortune 500 companies.”

The contract marks Unisys’ second contract it secured from DISA this year. Last month, the company secured a $152m contract to provide managed Cloud services to DISA’s Joint Service Provider programme, which manages the DoD’s IT infrastructure.

Earlier this year, the US Air Force awarded the company a $76m contract to provide a package of digital workplace services that securely manages, maintains and monitors the airforce’s end-user desktop, laptop and mobile devices.
