Seatac Marine Services, LLC

Seatac Marine Services, LLC, a veteran-owned maritime transportation company based in Seattle, Washington, operates exclusively as a prime contractor (100% of recent awards) providing deep-sea cargo charter and ocean intermodal distribution services to the Department of Defense and the Department of Transportation. The company is a for-profit limited liability company structured as a veteran-owned business, with primary NAICS classification 483111 (Deep Sea Freight Transportation) and secondary PSC codes reflecting marine charter and vessel freight services. Seatac competes predominantly under full-and-open (non-set-aside) IDC vehicles, though it secured multiple total small business set-aside purchase orders from the Military Sealift Command between 2022 and 2026.

Seatac's customer base is heavily concentrated in defense sealift: the Department of the Air Force accounts for approximately $4 billion in combined potential value across 5 awards, driven almost entirely by a single $4 billion multiple-award IDC under the Universal Services Contract 10 (USC-10) running through August 2026. The Department of the Navy's Military Sealift Command represents the second-largest customer by award count (8 awards) with $9.4 million combined potential value, reflecting voyage-specific dry cargo charter work. The company also serves the Department of the Air Force's Air Mobility Command, the Department of the Transportation's Maritime Administration (which awarded a $1,014,957 United States Marine Highway grant in May 2024 to fund a 70,000-lb capacity forklift for Seatac's Duwamish River Terminal in Seattle), and the Department of the Army and Department of the Navy's United States Pacific Fleet Forces in smaller volumes. The five customers account for 90% of awards by count and 100% of combined potential value.

Seatac holds two major IDCs. The $4 billion USC-10 multiple-award contract (Air Mobility Command, award date September 1, 2024, through August 31, 2026) provides ocean carrier and intermodal distribution services including containerized freight, hazardous materials, and heavy-lift cargo on U.S.-flagged vessels and tug-barge combinations worldwide. A separate Voluntary Intermodal Sealift Agreement (VISA) Contingency Services IDC (Air Force, award date October 1, 2024, through September 30, 2029, with one five-year option and six-month extension) provides contingency sealift capacity at zero dollars ceiling with funding through task orders. Seatac has placed 5 task orders under USC-10 ($157 thousand combined potential value) and 2 under the earlier DAMT0103D0087 IDC ($1 thousand combined potential value).

Recent representative work includes a $797,750 total small business purchase order from Military Sealift Command (award date March 13, 2026) for dry cargo voyage charter from Naval Magazine Indian Island, Washington to Valdez, Alaska using a Jones Act-compliant vessel (delivery April 15–17, 2026); an $815,600 total small business purchase order from Military Sealift Command (award date August 26, 2025) for tug-barge dry cargo charter from Naval Magazine Indian Island to Valdez (delivery September 21, 2025); a $2.4 million total small business purchase order from Military Sealift Command (award date April 18, 2023) for containerized ammunition transportation between California and Hawaii; and multiple delivery orders under USC-10 from the Air Force ($101,198.72 in November 2024, $39,492.49 in August 2025, $11,128.16 in October 2025, $4,938.00 in December 2025) for consolidated transportation shipments utilizing decentralized ordering mechanisms.

Activity has accelerated over the past four years — one award in 2022, two in 2023, five in 2024, four in 2025, and one in 2026 as of mid-March. However, the vendor's obligated dollar value ($10.8 million) represents only 0.27% of combined potential value, reflecting the large ceiling but minimal task-order activity on the $4 billion USC-10 vehicle to date. Three awards (representing $815,600 in potential value from the MSC purchase orders) reached completion in 2025, and one ($797,750 from the March 2026 MSC charter) completes in April 2026, creating recompete opportunity in that near term. The federal grant award from the Maritime Administration carries an ultimate completion date of January 15, 2030.
