Curtin Maritime Corp

Curtin Maritime Corp, a for-profit subchapter S corporation based in Long Beach, California, delivers dredging, vessel towing, and maritime logistics services to federal agencies as a prime contractor on 64 awards (67% of recent activity) and as a subcontractor on 32 awards (33%). The vendor competes predominantly full-and-open; only two of its recent awards carry small-business set-asides (both Total Small Business designations with Military Sealift Command), with the remainder unset.

Curtin Maritime's prime capability portfolio centers on maintenance and construction dredging for Army Corps of Engineers civil works, with NAICS 237990 (Other Heavy and Civil Engineering Construction) covering 41 awards across its footprint. Representative dredging work includes a $34.3 million definitive contract from the Army for Houston Ship Channel dredging (September 2025, performance through July 2026), a $22.6 million contract from the Baltimore District for FY26 Baltimore Harbor and Channels maintenance dredging (November 2025, ultimate completion April 2026), and a $57.9 million San Juan Harbor construction and maintenance dredging contract from the Jacksonville District (July 2023, completed November 2024). The vendor also provides open-ocean vessel towing and barge operations under NAICS 483211 (Deep Sea Freight Transportation), exemplified by a $2.26 million open-ocean tug services purchase order from Military Sealift Command for the T-EPF FALL RIVER voyage tow from Pearl Harbor to Brownsville, Texas (August 2025, completed November 2025). A cooperative agreement with the Maritime Administration (awarded December 2023, extending through January 2027) funds hybrid dredge and electric-assist tug design and demonstration. In its subcontractor role, Curtin supplies tug and barge vessel services, charter vessel operations, and towage services under primes including Systems Application & Technologies Inc., BAE Systems Maritime Solutions San Diego Inc., Manson Construction Co, and others, with work spanning targets operations and maintenance, autonomous undersea vehicle development (MANTA RAY Phase 2), and subsea cable installation support.

Customer concentration tracks heavily toward Department of the Army Corps of Engineers entities. The Jacksonville District, general Army, Baltimore District, and San Francisco District account for $268 million combined potential value across 35 awards, representing roughly 70% of the portfolio's dollar total. By award count, Naval Air Warfare Center (18 awards, $5 million), Military Sealift Command (14 awards, $13.9 million), and San Francisco District (11 awards, $47.1 million) lead among 23 distinct customer agencies. The vendor maintains IDCs with Naval Supply Systems Command ($13.8 million ceiling, Total Small Business set-aside, San Clemente Island Barge Services through September 2027) and the Air Force ($0 ceiling, multiple-award Voluntary Intermodal Sealift Agreement contingency services for vessel capacity, through September 2034).

Activity has grown substantially—from 3 awards in 2022 to 22 in 2025—with 96 total awards (prime and sub combined) carrying $384.8 million combined potential value. Obligated dollars stand at $366.6 million (95% of potential value), indicating strong execution and payment velocity. Three awards face ultimate completion within the next twenty-four months with combined potential value of $39.2 million, creating near-term recompete exposure. The vendor's award footprint spans domestic and overseas locations including Baltimore, Houston, San Francisco, Norfolk, San Juan Puerto Rico, and northern California waterways, with performance concentrated in Corps of Engineers harbors, Navy installations, and military sealift operations.
