What it is
- Maritime Systems is a research and development program run by U.S. Special Operations Command (SOCOM) whose mission is the Engineering and Manufacturing Development of Special Operations Forces (SOF) surface and undersea mobility platforms — combatant craft and combat submersibles.
- The program is funded through the Research, Development, Test and Evaluation, Defense-Wide account.
- The program is organized into two main projects: Underwater Systems (project number S0417) and Surface Craft (project number S1684).
- The Underwater Systems project covers development of combat submersibles, SOF combat diving systems, underwater support systems, and underwater equipment used for infiltration/extraction, personnel/material recovery, reconnaissance, and other missions.
- The Surface Craft project covers development of all combatant craft, combatant craft mission equipment, product improvements, and technology insertions to meet the unique requirements of SOF.
- One underwater effort is the Dry Combat Submersible (DCS), a surface-launched, dry, atmosphere-controlled vessel that can insert and extract SOF personnel and their equipment into denied areas; SOCOM tested one submersible prototype to validate test methods and safety certification.
- Another underwater effort is the Sea, Air, and Land (SEAL) Delivery Vehicle (SDV) MK 11, a free-flooding combat submersible being developed to replace the legacy MK 8 MOD 1 system, with one Engineering Development Model and ten production units planned.
- Surface efforts include the Combatant Craft Medium (CCM), a semi-enclosed multi-mission craft with a 40-knot speed, 600-nautical-mile range, and capacity for 4 crew plus 19 passengers, described as Naval Special Warfare's craft-of-choice for long-range, high-payload operations.
- Another surface craft, the Combatant Craft Assault (CCA), is a 41-foot combatant craft for squad-size operations with a 40-knot speed and 300-nautical-mile range that is transportable by C-130, C-17, or C-5 aircraft.
- The program also includes the Special Operations Craft Riverine (SOCR), an aluminum-hull platform for short-range insertion of SOF in riverine and littoral areas.
- Newer development includes the Small Unmanned Surface Vehicle (SUSV), which procures commercial-off-the-shelf modular systems for short-endurance and long-endurance unmanned maritime missions.
Why it matters
- For fiscal year 2024, the program had actual spending of about $158.9 million (shown as 158,929 in thousands of dollars).
- For fiscal year 2025, the enacted funding was about $200.8 million (200,770 in thousands of dollars).
- The fiscal year 2026 total request is about $301.3 million (301,288 in thousands of dollars).
- The FY2026 total combines a discretionary request of about $120.5 million (120,475 in thousands) with a reconciliation (mandatory) request of about $180.8 million (180,813 in thousands).
- The reconciliation portion of the FY2026 request is about $180.8 million (180,813 in thousands of dollars).
- Funding rose by about $100.5 million from FY2025 to FY2026, a roughly 50% increase — a large year-over-year jump that signals a major expansion of the program.
- According to the program narrative, the FY2026 reconciliation funding is tied to Section 20009 (INDOPACOM Capabilities) of the Reconciliation Exhibit, reflecting priorities in the Indo-Pacific region.
- The program narrative breaks FY2026 into $246.2 million unclassified and $55.0 million classified, showing that a portion of the work is not publicly detailed.
Key players
- The program is managed by U.S. Special Operations Command (SOCOM).
- Lobbying filings by Lockheed Martin Corporation in 2025 referenced maritime-related issues in connection with HR 1, the One Big Beautiful Bill Act, Title II.
- General Dynamics Corp filings in 2024 and 2025 reported lobbying that referenced maritime matters alongside FY24, FY25, and FY26 Defense Appropriations issues.
- A General Dynamics filing reported lobbying on issues related to the Maritime Administration and Ready Reserve Sealift recapitalization.
- BAE Systems Land & Armaments LP filings in 2025 and 2026 reported lobbying on issues relating to military vehicles, munitions, and maritime systems.
- L3Harris Technologies Inc filings in 2024 referenced maritime matters in connection with the National Defense Authorization Act for Fiscal Year 2025.
- Because these lobbying mentions are only correlational — a filing referenced maritime topics — they do not indicate that any company won work or influenced the program.
