About this award
The National Science Foundation Division of Polar Programs awarded a $3.418795 billion cost-plus-award-fee definitive contract to Leidos, Inc. for science operation and maintenance support for the United States Antarctic Program on December 23, 2011, with an ultimate completion date of September 30, 2027.
The contract sustains logistics, fielding, and operational support across the U.S. Antarctic Program, encompassing flight operations, cargo movements, facilities management, and construction. Place of performance is Antarctica.
MOD 186 represents the FY27 annual program plan update within a multi-year delivery framework that has run since the original award date. In January 2026, NSF published a Justification and Approval for non-competitive extension of the contract's period of performance by twelve months (September 30, 2026, through September 30, 2027) under FAR 6.302-3, citing industrial mobilization, engineering, and expert-services capability justifications, with an estimated extension value of $225 million to ensure operational continuity during the follow-on Antarctic Support Contract source selection.

Primary subcontractors include SHI International Corp (software licensing and IT infrastructure), Carahsoft Technology Corp (enterprise software solutions), Logistics365 Inc. (vehicles and supply chain), and a multi-vendor network of equipment suppliers, facilities support providers, and specialized-services vendors including Bauer Compressors, Zodiac Of North America (maritime equipment), Wagner Equipment Co (Caterpillar heavy equipment maintenance), and numerous small business providers across construction, food service, electrical, marine, and industrial equipment categories.
