Yamaguchi Machinery Co.,Ltd.

Yamaguchi Machinery Co., Ltd., a Japan-based international organization, operates exclusively as a prime contractor delivering specialized maritime equipment repair, fabrication, testing, and maintenance services to the U.S. Navy across multiple amphibious and mine countermeasures vessel classes. The vendor competes entirely under full-and-open, non-set-aside federal procurement and holds no SBA certifications or domestic small-business designations. All work is performed at the vendor's facilities in Japan; the company maintains no subcontracting footprint.

Yamaguchi Machinery's federal footprint is narrowly concentrated on naval ship repair and maintenance. The top five customer entities—Naval Sea Systems Command (NAVSEA), United States Pacific Fleet Forces, Naval Supply Systems Command (NAVSUP), Military Sealift Command, and Naval Facilities Engineering Command—account for 100 percent of recent awards by volume. NAVSEA dominates the relationship, representing 1,712 awards valued at $72.5 million in combined potential value; Pacific Fleet Forces adds 751 awards at $14 million. This concentration reflects the vendor's strategic positioning as a forward-deployed repair resource for the Navy's Pacific amphibious and mine countermeasures fleets. Recent capability work spans component-level ship maintenance across the San Antonio-class (LPD-18, LPD-20, LPD-22), Whidbey Island-class (LSD-47), America-class (LHA-6, LHA-7), Avenger-class (MCM-7, MCM-9, MCM-10, MCM-14), and expeditionary support vessel (APL-40) platforms. Representative delivery orders include $909 thousand for stern gate preservation, gasket replacement, and hinge repair on LPD-22 (February 2026); $541.6 million for repair and maintenance of an LSD-47 20-ton topside crane (May 2024); and $400.6 million for APL-40 pump-out and checkout services with period-of-performance extension (December 2024).

Yamaguchi Machinery operates under four active single-award Basic Ordering Agreements with Naval Supply Systems Command. The largest vehicle, BOA N6824617G0023, carries 547 task orders valued at $27.7 million in combined potential value. BOA N6824621G0023, the primary vehicle supporting recent work, has issued 444 task orders worth $25.1 million combined. Two additional IDCs—N6824613G0023 and N6824608G0023—anchor 697 and 578 task orders respectively at $19 million and $13 million combined potential value. All four vehicles function as streamlined indefinite-delivery mechanisms governed by Defense Federal Acquisition Regulation Supplement Subpart 217.71, enabling NAVSEA and NAVSUP to rapidly procure specialized maritime maintenance and repair services without individual competitive procurements for each delivery order.

Activity has declined modestly year over year—109 awards in 2022 to 42 in 2026 (through July)—reflecting seasonal and vessel-availability fluctuations characteristic of Navy ship repair. Thirty-three awards (combined potential value $1.8 million) reach ultimate completion within the next twenty-four months and therefore face recompete. The vendor's primary NAICS classification is Ship Building and Repairing (2,460 awards), with non-nuclear ship repair (west) as the dominant PSC category (2,457 awards). Yamaguchi Machinery has maintained continuous federal engagement with the Navy since at least 2005, demonstrating sustained competitiveness in open-market procurement for technical maritime services supporting Pacific amphibious warfare and mine countermeasures fleet readiness.
