Yamaguchi Machinery Co.,Ltd.

Yamaguchi Machinery Co., Ltd., a Japan-based international organization, performs specialized maritime equipment repair, fabrication, testing, and maintenance services for U.S. Navy vessels as a prime contractor under single-award Basic Ordering Agreements, with all work performed at its facilities in Japan and no subcontracting footprint.

Yamaguchi Machinery operates exclusively under full-and-open, non-set-aside federal procurement. The company's work is narrowly concentrated on Navy ship repair and maintenance: the primary NAICS is Ship Building and Repairing (2,445 of 2,472 awards), and the top PSC code is Non-Nuclear Ship Repair (West) (2,442 awards). Recent representative delivery orders exemplify the work profile. In March 2026, Naval Sea Systems Command issued repair and replacement orders for fuel filter enclosures, flexible hose assemblies, and air conditioning components on MCM-9 mine countermeasures craft ($49,856). In February 2026, NAVSEA awarded a tank inspection and pump unit replacement on an APL-40 auxiliary vessel ($351,358). In January 2026, the command issued a vacuum, collecting, holding, and transfer system piping replacement on LPD-22 amphibious transport dock ($104,277). These orders exemplify the vendor's steady engagement in component-level ship maintenance across multiple vessel classes.

Customer concentration is extreme and Navy-centric. The Department of the Navy's Naval Sea Systems Command accounts for 1,696 of 2,472 awards (68% by count) and $72 million of $87.2 million combined potential value (83%). The Navy's United States Pacific Fleet Forces places a distant second with 751 awards and $14 million combined potential value. The Naval Supply Systems Command, Naval Facilities Engineering Command, and Military Sealift Command account for the remaining 22 awards. This concentration reflects Yamaguchi Machinery's role as a forward-deployed, in-theater repair vendor supporting the Navy's Pacific amphibious and mine countermeasures fleets.

Yamaguchi Machinery operates under four primary parent vehicles, all single-award Basic Ordering Agreements. The highest-activity BOA is N6824621G0023 (Naval Supply Systems Command), awarded August 9, 2021, valid through July 30, 2026, with 429 delivery orders and $24.6 million combined potential value. BOA N6824617G0023 carries 547 task orders and $27.7 million, while N6824613G0023 and N6824608G0023 account for 697 and 578 task orders respectively. The company holds no position on governmentwide GWACs, agency-wide IDIQs, or civilian vehicles; all work flows through these Navy-specific indefinite delivery mechanisms.

Activity remains steady across recent years—109 awards in 2022, 102 in 2023, 97 in 2024, 77 in 2025, and 27 awards year-to-date in 2026—reflecting consistent Navy demand for in-theater maintenance. Thirty-eight awards (combined potential value $3.2 million) complete within the next twenty-four months, creating targeted recompete exposure primarily tied to BOA N6824621G0023, which expires July 30, 2026. This BOA represents the vendor's largest active vehicle and faces renewal competition in mid-2026.

Yamaguchi Machinery has maintained continuous federal contracting with the Navy since at least 2005 (twenty-one years of documented activity). The vendor operates as a sole proprietor with no visible domestic subsidiary or teaming structure; all work is delivered directly from Japan-based facilities. The company is foreign-owned and does not carry SBA certifications or domestic small-business set-aside designations. Its entire federal footprint consists of competitive, open-market delivery orders against Navy maintenance BOAs, positioning it as a specialized logistics partner rather than a general government contractor. The vendor's strategic value lies in forward-deployed geographic advantage and specialized technical capability for ship repair in Pacific-based facilities where the Navy requires rapid access to maintenance services without individual competitive solicitation for routine component replacements and system repairs.
