Welcome to STIDD Submersible Boats STIDD Sub-Boats, outfitted with the latest technical innovations, redefine what is possible for SOF units combating both asymmetric and traditional maritime threats.
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.
Over the past 20 years, STIDD built its Submersible line and flagship product, the Diver Propulsion Device (DPD), around the basic idea that divers would prefer riding a vehicle instead of swimming.
Today, STIDD focuses on another simple, but transformative goal: design, develop, and integrate the most advanced Precision Navigation, Control and Automation Technology available into the DPD to make that ride easier, more effective, and when desired . . . RIDERLESS!
