About Foss Maritime Company, Llc.

Written by GovTribe AI ·

Foss Maritime Company, LLC, a woman-owned for-profit division of Saltchuk Resources, Inc., headquartered in Seattle, Washington, provides tugboat services, harbor tug operations, towing and rescue support, and emergency vessel escort to the U.S. Coast Guard, Department of the Navy, and Department of Homeland Security as a prime contractor (89% of recent awards) and subcontractor. The vendor competes full-and-open, with no set-aside designations across its prime footprint.

Foss Maritime's customer concentration sits heavily with the Coast Guard and Navy. The top five customer agencies account for 81% of recent awards by count, led by the Department of the Navy (129 awards, $374 thousand combined potential value across the slice shown) and the Department of Homeland Security US Coast Guard (65 awards, $106.4 million), followed by the Department of the Navy Military Sealift Command (65 awards, $34.7 million), the Naval Air Systems Command Naval Air Warfare Center (43 awards), and Naval Sea Systems Command (25 awards, $8 million). By potential value, the top three customers shift: the Coast Guard (65 awards, $106.4 million) and Military Sealift Command (65 awards, $34.7 million) remain dominant, followed by FEMA Incident Support Section ($24.1 million on a single award). Recent representative work includes a $247.4 thousand emergency tug escort purchase order from the Coast Guard for urgent vessel casualty response in Seattle (July 2026); a $1.819 million delivery order from Navy Installations Command for harbor tug services at Naval Station Seal Beach, California (October 2025); a $121.3 thousand purchase order from the Coast Guard for tug services supporting USCGC Healy transit through the Columbia River (June 2026); and a $316 thousand delivery order from Army Surface Deployment and Distribution Command for S&RTS Seattle services (January 2023).

Foss Maritime holds two prime indefinite delivery contracts: a single-award $4.125 million Navy Installations Command contract through March 2028 for call-out tug services at Seal Beach and San Diego ports, and a multiple-award Air Force Voluntary Intermodal Sealift Agreement (VISA) contingency services contract awarded October 1, 2024, with a ten-year ceiling through September 30, 2034 for worldwide Department of Defense sealift and ocean transportation charters. The Navy Installations Command contract has generated multiple delivery orders against it totaling $1.819 million in recent years. Foss Maritime places task orders under Navy Indefinite Delivery Contract N0003303D1015 (36 task orders, $374 thousand combined potential value), N0040694D4030 (15 task orders), N0040602D5009 (12 task orders, $2.1 million), N0040692D0272 (12 task orders), and Basic Ordering Agreement DTCG8993A68F911 (8 task orders, $46 thousand).

Activity has been uneven. The source shows 403 total awards spanning from 1981 to the present, with nine awards in 2022, a spike to 34 awards in 2023, then a decline to 11 in 2024, six in 2025, and three awards to date in 2026. Only one award (combined potential value $1.8 million) faces ultimate completion within the next twenty-four months, presenting minimal recompete exposure in that window. Foss Maritime subcontracts principally to Systems Application & Technologies Inc. on multiple "TARGETS Operations & Maintenance Contract Vessel Tug Support" task orders, and to Vigor Marine LLC on vessel delivery and tug operations (two awards in 2023 and 2024 for USNS Guadalupe and USNS Henry J. Kaiser inbound transits). The parent company, Saltchuk Resources, Inc., also owns Foss International LLC and Young Brothers LLC. Foss Maritime's capability footprint centers on vessel towing, harbor operations, and emergency maritime logistics, with top NAICS concentrations in Navigational Services to Shipping (116 awards), Aircraft Manufacturing (43 awards, routed through Naval Air Warfare Center work), and Inland Water Freight Transportation (21 awards), and top PSC codes in Transportation/Vessel Towing (106 awards), Non-Nuclear Ship Repair West (55 awards), and Marine Charter (46 awards).
