The vendor competes full-and-open with no set-aside designations across all 241 recent awards in the source data, which span from 1983 to November 2025.

Sasebo's capability portfolio centers on naval vessel maintenance and repair across multiple ship classes. Representative work includes a $10.3 million delivery order from Naval Supply Systems Command (November 2024) for comprehensive ship repair management, scheduling, testing, and quality assurance supporting the USS PATRIOT (MCM-7) Docked Selected Restricted Availability through April 2026; a $1,038,046 delivery order from Naval Sea Systems Command (October 2024) for MCM-7 docking and undocking services; a $584,732 delivery order from Naval Sea Systems Command (November 2025) for dry docking, hull repairs, modifications, and preservation work on various naval vessel types; a $441,268 delivery order (June 2025) for MCM-7 deck and bulkhead repairs; and a $367,142 purchase order (September 2025) for fire damage cleaning services on naval decks. Work covers Landing Ship Docks (LSD-47, LSD-48), minesweepers (MCM-7), Landing Platform Dock vessels (LPD-18, LHA-6), workboats, harbor security boats, and auxiliary craft. All work is performed at Sasebo's facility in Japan, supporting U.S. Navy fleet readiness in the Asia-Pacific region.

Customer concentration is nearly absolute with the Department of the Navy. The Navy accounts for 195 of 225 tracked awards (94% coverage by count) across all funding components, with Naval Sea Systems Command (18 awards, $5.2 million combined potential value), Naval Supply Systems Command (2 awards, $10.3 million), and Navy Installations Command (10 awards, $2.9 million) serving as primary task-order issuers. The Department of the Army holds 2 awards. By dollar value, Naval Supply Systems Command anchors the portfolio with $10.3 million, followed by Naval Sea Systems Command with $5.2 million.

Sasebo holds positions on four active BOAs. The two highest-volume vehicles—BOA N6264985H4201 (84 task orders) and BOA N6264988H0401 (38 task orders)—carry no disclosed ceiling values in the source. BOA N6264923G0004, the visible primary vehicle, has issued 13 task orders worth $14 million combined potential value. BOA N6824619G0001 has generated 14 task orders valued at $4.1 million combined potential value. Indefinite Delivery Contract N6240483C0008 supports 4 task orders.

Activity over the past five years shows modest volume with 7 awards in 2021, declining to 3 in 2022 and 2023, recovering to 7 in 2024, and 5 in 2025 year-to-date. The combined potential value across all recent awards stands at $18.4 million, though the combined dollars obligated ($48.7 million) exceeds this ceiling by 264 percent—reflecting multiple years of execution against individual task orders. Primary category concentration sits with Ship Building and Repairing (30 awards) and Maintenance/Repair/Rebuild of Equipment—Ships, Small Craft, Pontoons, and Floating Docks (186 awards, PSC code). The vendor operates subsidiaries including Sasebo Heavy Industries Co., LTD. and Sasebo Marine and Port Services Co., LTD.; the division name "USN Project Team" reflects its dedicated Navy customer focus within the larger corporate structure.
