Leidos has secured a contract to support the operation and maintenance of the US Defense Threat Reduction Agency's (DTRA) meteorological data servers (MDS) and numerical weather prediction (NWP) service.
Valued at around $13m, the contract was awarded under DTRA's countering weapons of mass destruction (CWMD) contract vehicle.
The contract requires Leidos to provide targeted research and development to improve environmental data used in DTRA's atmospheric transport and dispersion models, which will enhance accidental release predictions for chemical, biological, radiological and nuclear defense (CBRNE) weapons.
This deal also covers improvements to the weather data collection and dissemination of weather products to DTRA's customers.
Leidos Group president Mike Chagnon said: "The Leidos team brings expertise in meteorology, developmental research, software engineering and system development to modernise and maintain DTRA's operational systems and weather product applications.
"We are proud to support DTRA's critical chemical, biological, radiological, nuclear and explosives (CBRNE) mission."
The contract has a one-year base period of performance and four one-year options.
Work under the contract will be carried out in San Diego, California and Ft. Belvoir, Virginia, US.
DTRA, which is a US Department of Defense agency, provides a central distribution centre for delivery of weather products that help product data applications to perform consequence assessments of accidental and intentional releases from CBRNE incidents.
The agency was established in 1998 to focus on terrorism, nuclear surety, and counter-proliferation.
