Serco has been contracted to upgrade the high-altitude electromagnetic pulse (HEMP) protection of ballistic missile early warning systems for the US Air Force (USAF).
The five-year contract was awarded under the US Army Corps of Engineers, Engineering and Support Center, Huntsville's Resilient Power and Mechanical Systems Basic Ordering Agreement.
Under the $38m contract, Serco will improve and modernise the radar's HEMP protection via a design-build-install-test approach for US Air Force Space Command and the US Strategic Command at Thule Air Base in Greenland.
Serco chairman and CEO Dan Allen said: "I am proud of our Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance (C4ISR) and Base Modernisation service teams for winning this new contract as we grow our business in the defence market sector.
"Our team has been supporting HEMP radar upgrades, and we look forward to continue delivering our services at the Thule Air Base in Greenland."
Serco has been upgrading HEMP radars for US Air Force Space Command at Clear Air Force Station, Alaska; Cavalier Air Force Station, North Dakota; Cape Cod Air Force Station, Massachusetts, US; and Royal Air Force Flyingdales, UK.
In April this year, the company received a $131m contract to deliver lifecycle sustainment support for the US Naval Facilities Engineering Command's (NAVFAC) C4I systems at global locations.
The contract requires the company to provide critical preventive and corrective maintenance, information assurance, asset management, technical systems updates, service call resolution, and configuration management for C4I systems.
