About Six Maritime, Inc.
Six Maritime, Inc., a San Diego-based service-disabled veteran-owned small business (SDVOSB), delivers specialized maritime training, tactical alpine mobility instruction, and unmanned surface vessel support to the Department of the Navy and U.S. Special Operations Command, operating as a prime contractor on 40% of recent awards and as a subcontractor on 60%, with recurrent sole-source and set-aside posture across its prime footprint. The company holds concurrent SBA certifications as both a veteran-owned small business and a service-disabled veteran-owned small business through November 2028, and is self-certified as a small disadvantaged business. Six Maritime is structured as a Subchapter S corporation and maintains a subsidiary, D6 International Corp.
The company's capability portfolio centers on three concrete domains. First, maritime operations and maintenance training: a $1.51 million firm fixed-price contract with Naval Sea Systems Command (awarded June 2022, completing August 2026) delivers Rigid Hull Inflatable Boat operations and maintenance courses spanning three-week basic operations (twelve-student capacity) and five-day proficiency tracks (six-student capacity) at Naval Station Mayport and Naval Air Station North Island in San Diego. Second, alpine and mountain mobility instruction: Six Maritime holds recurring sole-source and competitive awards from U.S. Special Operations Command for winter alpine mobility, avalanche training, and mountain mobility and survivability courses, with named awards valued at $33 thousand (January 2023) through $260.7 thousand (February 2025). Third, vessel relocation and crew training: a $193.2 thousand firm fixed-price award from the Air National Guard (September 2025, completing November 2025) covered relocation of three Mark VI Patrol Boats from Newport News, Virginia to the Alpena Coast Guard Training Center in Michigan, with crew transit and operator and maintenance training for ten personnel. In subcontractor capacity, Six Maritime provides chase boat support for Guidance and Autonomous Reconnaissance operations (GARC) unmanned surface vehicles under Maritime Applied Physics Corporation, with fifteen sub-award captures across 2024 and 2025.
Customer concentration is heavily skewed toward the Department of the Navy. Navy agencies account for 96% of award count (14 awards), anchored by Naval Sea Systems Command's $1.51 million RHIB training contract. The potential-value ranking is dominated by Naval Sea Systems Command's $10 billion ceiling, which reflects a single large-value vehicle rather than distributed high-volume activity — obligated dollars total only $4.4 million across all awards, revealing that most potential value remains unexercised. U.S. Special Operations Command places the second-largest customer footprint by award count (4 awards, $689 thousand combined value) and represents Six Maritime's established training customer base outside naval operations. Six Maritime holds one seat on the Seaport Next Generation vehicle via GSA Federal Acquisition Service, though with minimal historical task orders.
Activity accelerated sharply in 2025 with fifteen awards compared to one or two annually in 2022–2024. Awards reaching ultimate completion inside the next twenty-four months total one contract ($1.5 million, the Naval Sea Systems Command RHIB training order completing August 2026), representing limited recompete exposure in the near term. The prime-to-sub split (40/60) is inverted from typical small businesses, driven by the high volume of recurring chase boat support sub-awards under Maritime Applied Physics Corporation — these are monthly or near-monthly call-downs rather than discrete prime contracts, suggesting an ongoing operational support role rather than project-based engagement.
