San Denshi Kogyo Co.,Ltd.

San Denshi Kogyo Co., Ltd., headquartered in Sasebo, Nagasaki, Japan, is a for-profit international organization that provides specialized naval vessel maintenance, repair, and technical services to the U.S. Navy as a prime contractor through a single-award Basic Ordering Agreement with Naval Sea Systems Command (NAVSEA) established October 1, 2022. The vendor competes exclusively in the open market with no set-aside designations across its federal footprint.

San Denshi Kogyo's capability portfolio centers on ship maintenance and repair work performed in Japan supporting U.S. Navy operations throughout the Asia-Pacific region. Services include antenna preservation and replacement, cable installations, electrical system repairs, ventilation system maintenance, equipment upgrades, radar antenna refurbishment, generator component replacement, lighting fixture installation, and functional testing of shipboard systems across multiple vessel classes. Representative work includes a $191.3 thousand delivery order for MCM-14 SSDG exciter air gap correction awarded March 28, 2025; an $80.2 thousand delivery order for LHA-7 antenna replacement awarded June 17, 2025; and a $129.4 thousand delivery order for naval vessel maintenance and repair services awarded November 7, 2025. The vendor holds primary NAICS classification under Ship Building and Repairing (1,487 of 1,567 awards) and operates under PSC code for Non-Nuclear Ship Repair (West) covering the vast majority of its work.

Customer concentration is extreme and narrow. The Department of the Navy's Naval Sea Systems Command accounts for 1,005 awards (64% of the 1,567-award portfolio) valued at $19.4 million of the combined $25.6 million potential value. The Department of the Navy's United States Pacific Fleet Forces accounts for 454 awards valued at $4.4 million. Three additional Navy entities—Information Warfare Systems Command, Military Sealift Command, and Naval Supply Systems Command—account for the remaining customer base. The top two customers together represent 93% of awards by count and 96% of potential value, indicating severe concentration with a single naval customer and subordinate Navy commands.

San Denshi Kogyo operates delivery orders under five parent Basic Ordering Agreements and Indefinite Delivery contracts, all with NAVSEA. The primary vehicle is BOA N6264922G0007, which has generated 146 task orders valued at $3.7 million since the vendor's October 1, 2022 award. Three other BOAs (N6824614G0006, N6824618G0006, and N6824610G0006) account for 998 delivery orders combined, valued at approximately $18.7 million. All work is performed in Japan and priced firm fixed price with no set-aside designation.

Activity has remained consistent in recent years—49 awards in 2022, 41 in 2023, 54 in 2024, 26 in 2025, and 17 year-to-date in 2026. Only 14 awards with a combined potential value of $232 thousand face ultimate completion within the next twenty-four months, indicating limited recompete exposure in the near term. The vendor has no subcontractor footprint; all 1,567 awards are prime awards with zero sub-award activity. San Denshi Kogyo is the sole source of supply under its BOA structure, holding exclusive access to the contract vehicle through a single-award arrangement that limits competitive threat from other vendors on task order issuance.
