The U.S. Department of War has awarded Sierra Nevada Corp. (SNC) a $15 million contract to provide technical support, maintenance, and sustainment services for the Ukrainian Navy’s Counter-Unmanned Aircraft Systems (C-UAS) program, according to a contract announcement.
Under the agreement, Sierra Nevada will deliver product-based field services, including subject matter experts, to enhance the maintenance and operational readiness of C-UAS systems deployed with Ukrainian naval forces.
The contract also provides for “reach back” support — remote technical and engineering assistance — for various systems currently deployed across Eastern Europe under NATO operations.
Work under the contract will take place in multiple locations, including Rzeszów, Poland (52%), Englewood, Colorado (44%), and Fort Walton Beach, Florida (4%). The project is expected to be completed by September 2027. Funding will be provided through the Ukraine Security Assistance Initiative (Department of War Wide), with the full $14,997,575 obligated at the time of award.
The Naval Air Warfare Center Aircraft Division at Patuxent River, Maryland, is managing the contract, which was awarded as a sole-source acquisition.
Sierra Nevada Corp., headquartered in Englewood, Colorado, is a key U.S. defense contractor known for its expertise in electronic warfare, mission systems, and counter-drone technologies. Its work on the Ukrainian Navy’s program builds on a series of U.S. initiatives aimed at strengthening Kyiv’s ability to defend against evolving threats, including the rapid proliferation of loitering munitions and aerial surveillance platforms used by Russian forces.
The contract also supports NATO’s broader efforts to reinforce its eastern flank and enhance the interoperability of partner forces. By providing maintenance support and system expertise, the agreement ensures that Ukraine’s counter-drone assets remain operational and integrated into joint defense operations across the region.
