Our Products
STIDD manufactures innovative Multi-Purpose Craft for SOF and Marine Forces.
STIDD’s Multi-Purpose Craft 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 Intermediate Support Craft (MRISC) 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 Multi-Purpose Craft offer SOF and Marine units new capabilities to counter today’s increasingly asymmetric and unpredictable maritime threat environment.
