Nakajima Nozzle Co., LTD.

Nakajima Nozzle Co., LTD., a for-profit Japanese corporation headquartered in Sasebo, Nagasaki, manufactures and overhauls main propulsion diesel engine governors, fuel injection pumps, fuel injection nozzles, and hydraulic amplifiers for U.S. Navy vessels as a prime contractor under firm fixed-price delivery orders and purchase orders, with all work performed in Japan. The vendor competes in full-and-open, non-set-aside procurements exclusively and holds no IDVs of its own; it operates entirely as a delivery-order vendor against Navy Basic Ordering Agreements.

Nakajima's customer base is nearly monolithic. The Department of the Navy Naval Sea Systems Command accounts for 90 awards valued at $1 million in combined potential value (60% of the vendor's total footprint), followed by the U.S. Pacific Fleet Forces with 58 awards totaling $432 thousand. Military Sealift Command and Naval Supply Systems Command together represent the remaining four awards and $19 thousand. The vendor's concentration in NAVSEA reflects its role as a specialized repair provider for amphibious assault ships (LHA), amphibious transport dock ships (LPD), dock landing ships (LSD), mine countermeasure ships (MCM), and fleet replenishment oilers (TAO). Representative work includes a $62.8 thousand delivery order (March 2026) for new governor installation and calibration on 1B and 2A main propulsion diesel engines for LSD vessels; a $31.2 thousand delivery order (January 2025) for LPD-18 main propulsion diesel engine repair and calibration; and a $26.2 thousand delivery order (May 2025) for spare MPDE governor components for USS New Orleans (LPD-18).

Nakajima sits on four Navy BOAs, collectively anchoring its order flow. Basic Ordering Agreement N6824622G0010 with Naval Supply Systems Command, effective October 2021 through September 2026, has generated 28 delivery orders valued at $513 thousand. BOA N6824617G0010 produced 26 orders totaling $305 thousand, BOA N6824608G0010 produced 23 orders for $183 thousand, and BOA N6824613G0010 produced 21 orders for $169 thousand. Combined, these four BOAs represent 98 of the vendor's 152 awards across its recent footprint.

Activity has remained episodic. Seven awards in 2022, six in 2023, four in 2024, and eight in 2025 reflect inconsistent demand flow tied to Navy maintenance scheduling rather than systematic growth. Recompete exposure in the next twenty-four months is minimal: only one award (worth $8 thousand) is scheduled to complete by October 2026. The vendor holds no subcontractors and performs no sub work; all 152 awards are prime contracts. Nakajima's footprint is NAICS 238490 (Ship Building and Repairing) at 143 of 152 awards and PSC category Non-Nuclear Ship Repair (West) at 148 of 152 awards, reflecting its specialized niche in foreign-performed Navy propulsion system maintenance.
