About South Bay Sand Blasting And Tank Cleaning, Inc.
South Bay Sand Blasting And Tank Cleaning, Inc., a minority-owned, Hispanic American small business headquartered in National City, California, provides naval vessel industrial maintenance and preservation services to the Department of the Navy as a prime contractor (72% of recent awards) and as a subcontractor to major shipbuilders. The company competes predominantly under total small business set-asides on its prime NAVSEA work and serves as a specialized sub on docking selected restricted availability (DSRA) and continuous maintenance availability (CMAV) programs across multiple shipyards.
South Bay's customer concentration is extreme and Navy-focused. The top five funding agencies account for 98% of awards, with Naval Sea Systems Command (NAVSEA) anchoring 1,597 awards (91% of the portfolio) valued at $307 million combined potential value. The Department of the Navy Installations Command, the Military Sealift Command, and US Pacific Fleet Forces represent the remaining material slice. This concentration reflects South Bay's positioning as a single-mission vendor: industrial cleaning, surface preservation, and painting for Navy vessels within and near the San Diego region.
South Bay holds two large NAVSEA IDIQs under which the majority of its prime work flows. The company's $30.3 million indefinite-delivery contract (effective through July 2027) covers commercial industrial services—heat exchanger, condenser, and cooler cleaning—within 50 miles of San Diego; the source references over 200 task orders placed against this vehicle. The company's $8.7 million preservation services IDIQ (effective through November 2026) covers surface preparation and painting for Navy vessels in the same geographic footprint; task orders under this vehicle include removal of existing paint coatings, surface preparation, and application of new coating systems. Additional named IDIQ vehicles include contracts for non-skid deck covering work and other specialized ship repair services. Concrete prime awards include a $897 thousand definitive contract for support marine reserve group flush services in Japan (February 2024), a $163 thousand hydraulic oil service contract (September 2024), $102 thousand for USS Chafee preservation work (December 2024), and numerous smaller delivery orders for heat exchanger cleaning, tank cleaning, and fuel offloading labor rates across destroyers, cruisers, amphibious warfare ships, and littoral combat ships.
In its subcontractor role, South Bay performs preservation, sandblasting, tank cleaning, and non-skid coating work for major Navy shipbuilders and ship repair firms. The company subcontracts regularly to BAE Systems Maritime Solutions San Diego and Norfolk, National Steel and Shipbuilding Company, Metro Machine Corp, Delphinus Engineering, Vigor Marine LLC, and smaller repair yards. Subcontract work includes USS Essex docking selected restricted availability (DSRA) preservation work (multiple BAE Systems San Diego awards from 2024 onward), USS Carter Hall (LSD 50) DSRA direct subcontract costs (BAE Systems Norfolk, repeated awards through 2025), USS Harpers Ferry repair sub-contracts (National Steel and Shipbuilding Company), and USS America docking selected restricted availability (National Steel and Shipbuilding Company, September 2025). The company also subcontracts ship and air C5ISR systems support work to General Dynamics Information Technology.
Activity has been volatile year over year—43 awards in 2022, 281 in 2023, 173 in 2024, 121 in 2025, and five awards in early 2026 as of the snapshot date. The category concentration reinforces South Bay's mission: 1,451 awards (83% of the portfolio) carry NAICS 336611 (Ship Building and Repairing), with secondary concentration in septic tank services, hazardous waste treatment, and hazardous waste collection reflecting the industrial cleaning scope. The top PSC code is Non-Nuclear Ship Repair (West), covering 897 awards. South Bay has been registered in SAM.gov since 2001 and demonstrates consistent track record across destroyer, cruiser, amphibious warfare, and littoral combat ship classes, supporting NAVSEA's fleet maintenance and modernization mission at installations concentrated in Southern California and Norfolk regions.
