STIDD Systems was founded in 1991 as a manufacturer of Government and Commercial Marine Seating. In 1998 it began development of its first Military Submersible. Today its customers include the United States Marine Corps, Special Operations Command, Coast Guard and Coalition Forces.


STIDD Systems, Inc. Occupies a 1.5 acre shipyard with 62,000 square feet of computerized manufacturing facilities, design and administrative offices located on the Greenport, Long Island harbor, approximately 90 statute miles due east of New York City and 16 nautical miles southwest of New London, CT.

STIDD Systems’ facility has been in continuous use as a shipyard since 1831. In World War I, the shipyard built 60 ft. patrol boats, and during World War II, the yard set Navy production records, delivering 440 136 ft. minesweepers and 1100 landing craft with a labor force of 7500 workers on three shifts .

STIDD Systems opened its Surface and Underwater Mobility Training and Evaluation Facility located in Marathon Key Florida in 2003. The “STIDD SOUTH” facility is approximately 47 miles North of Key West and 112 miles south of Miami.

Marathon provides an ideal location for not only conducting sea trials of STIDD’s Surface and Underwater Mobility Platforms but also gives prospective customers and new users a professional environment to evaluate our craft.
Stidd Company Profile 640

STIDD manufactures innovative Submersible Boat for SOF and Marine Forces. STIDD’s Submersible Boats benefit from the same design, engineering and quality manufacturing techniques that have made STIDD marine seats world famous.

The STIDD Diver Propulsion Device (DPD) is the most widely used two man underwater mobility platform in the world. The Multi-Role Combat Craft (MRCC) is the only craft of its kind that operates on the surface and while submerged.

The DPD and MRCC, used either separately or together as a modular submersible platform, offer the unique combination of both surface and underwater capabilities, providing maritime forces unprecedented options for mission planning and execution.

STIDD’s line of Submersible Boats offer SOF and Marine units new capabilities to counter today’s increasingly asymmetric and unpredictable maritime threat environment.
