Sumitomo Heavy Industries, LTD

Sumitomo Heavy Industries, LTD, a Japanese manufacturer headquartered in Japan, operates as a prime contractor delivering ship repair, maintenance, and sustainment services to the U.S. Navy as an international organization with no SBA certifications or set-aside eligibility. The vendor competes exclusively on full-and-open, non-set-aside delivery orders and holds no socioeconomic designations. Its federal footprint is heavily concentrated in Naval Sea Systems Command work—5,573 awards (97% of award count) with $1.85 billion in combined potential value—anchoring a $2.96 billion portfolio across six thousand-plus awards since 2002.

Sumitomo's capability portfolio centers on forward-deployed naval ship repair and maintenance. Representative work includes a $14.56 million delivery order from Naval Sea Systems Command for USS Blue Ridge (LCC-19) fiscal year 2026 CNO 5C1 TYCOM3 maintenance and repair (May 29, 2026), a $13.38 million delivery order for USS Blue Ridge (LCC-19) 5C1 DSRA TYCOM 1 docking availability work (May 29, 2026), and a $22.47 million delivery order for USS Blue Ridge (LCC-19) FY26 CNO 5C1 Bundle 3 ship repair (May 29, 2026). Work scope spans exterior hull repairs, equipment replacements, piping and electrical system work, tank preservation, structural fabrication, and specialized preservation for guided missile destroyers, aircraft carriers, amphibious transport docks, landing craft utility vessels, and auxiliary vessels. The vendor performs work directly from Japan-based shipyard facilities at Commander Fleet Activities Yokosuka and does not engage subcontractors on federal delivery orders, positioning itself as a single-source provider for forward-deployed naval asset maintenance without requiring vessel transit to the continental United States.

Customer concentration is extreme. Naval Sea Systems Command accounts for 97% of awards (5,573) and 95% of combined potential value ($1.85 billion of the $2.96 billion total). The Department of the Army Materiel Command TACOM Life Cycle Management Command ranks second by potential value at $687.1 million (11 awards, 0.2% of award count), followed by the Army Corps of Engineers Engineering District Japan ($127 million, 33 awards), Navy Installations Command ($87.8 million, 81 awards), and U.S. Pacific Fleet Forces ($59.2 million, 423 awards). The rankings reveal sharp tension: NAVSEA dominates both volume and dollars, while the Army contract vehicle carries substantial per-award magnitude but minimal award frequency. Most customer agencies are secondary or tertiary.

Sumitomo operates under five major Naval Sea Systems Command Basic Ordering Agreements and Indefinite Delivery Contracts anchoring its federal presence: N6264914G0004 (830 task orders, $206.7 million), N6264917G0006 (765 task orders, $245.2 million), N6264921G0002 (646 task orders, $335.7 million), N6264910G0003 (631 task orders, $122.2 million), and N6824609G0024 (618 task orders, $51.7 million). On January 30, 2026, TACOM awarded a multiple-award indefinite delivery contract valued at $69.768 billion with a completion date of July 30, 2031, for Army Watercraft Sustainment Maintenance Program Zone 3: Pier Side services in Japan. The TACOM vehicle is nascent—two $1,000 start-of-work meeting delivery orders issued as of February 15, 2026—but carries massive potential scope. The vendor also holds a $250,000 single-award Blanket Purchase Agreement with Naval Supply Systems Command for abrasive materials through December 9, 2028. Sumitomo participates in the SeaPort-e multiple-award contract, enabling delivery of technical support and preservation services for forward-deployed naval assets, though individual task-order detail is not surfaced in the source.

Activity has declined significantly year over year: 290 awards in 2022, 206 in 2023, 121 in 2024, 131 in 2025, and 100 in the first seven months of 2026 (annualized trajectory suggests 170–200 full-year awards). The 39 awards with completion dates inside the next twenty-four months carry combined potential value of $99.3 million, representing modest recompete exposure relative to the overall portfolio. Most recompetes will likely renew under existing NAVSEA BOAs and IDCs where Sumitomo holds established relationships.

Service Contract Inventory reporting is negligible. The SCI dataset captures 15 records (13 as prime, 2 as named subcontractor) across FY2022–FY2025 with zero invoiced revenue and minimal FTE activity (7.2 FTEs in FY2022, declining to 0.1 FTEs in FY2025). SCI exclusion of goods procurement and the vendor's reliance on firm fixed-price delivery orders for physical repair work means SCI captures almost none of Sumitomo's actual federal footprint. This is a shipyard repair vendor, not a labor-hour service contractor; treating SCI figures as representative of federal engagement would fundamentally mischaracterize the company.

Sumitomo operates as a prime contractor on 100% of awards (6,536 primes, 9 subs of 6,545 total), performing directly without subcontractor involvement on its core Navy ship repair work. The two subcontract records on file reflect sub-awards to General Dynamics Information Technology on C5ISR systems support tasks (December 19, 2025, and October 6, 2025), representing a peripheral secondary role distinct from Sumitomo's primary business model. The vendor neither primes work for other large defense contractors nor feeds substantial labor or material to primes through regular subctracting.

Sumitomo's corporate structure shows the child entity Sumitomo Heavy Industries, LTD (UEI JZUMWWR4MAF7) under the parent Sumitomo Heavy Industries, LTD. (UEI XA68KDK7TUY8), both Japanese entities. The parent is the registered federal contractor; the child is the operating prime under the source data. Primary NAICS 327122 (Abrasive Product Manufacturing) and 336611 (Ship Building and Repairing) reflect work scope, with 6,002 awards under Ship Building and Repairing. Top PSC is Non-Nuclear Ship Repair (West) at 5,764 awards, reinforcing geographic and capability concentration in Pacific forward-deployed naval asset maintenance. The vendor has no domestic U.S. presence, no facilities outside Japan, and no competitive footprint in continental U.S. shipyards or inland waterways. Its federal strategy is narrowly specialized: long-term reliance on Japan-based Navy repair contracts, with recent Army Watercraft expansion marking a strategic diversification attempt outside pure Navy work.
