Fast Boat Submarine (FBS) is a 45‑foot vessel that combines high‑speed surface travel with an instant‑dive, dry‑cabin submarine, allowing operators to transition from water to underwater missions with a simple switch. Powered by twin turbocharged diesel engines and an onboard battery system, the platform offers long‑range mobility, hyper‑ballasting for shallow‑water operation, and modular cabin configurations for military or commercial subsea tasks.

Problem
Traditional maritime platforms require separate vessels for surface travel and underwater operations, leading to logistical complexity, delayed mission transitions, and limited access to shallow or near‑shore environments. Operators lack a single, versatile system that can rapidly move on the surface and then submerge without extensive preparation.
Solution
Fast Boat Submarine (FBS) combines a high‑speed surface craft with a true dry‑cabin submarine in one platform. Twin turbocharged diesel engines provide long‑range surface mobility, while an onboard battery system enables instant submersion at the flip of a switch. The vessel’s hyper‑ballasting system and 30,000 lb lift capacity allow it to operate in extremely shallow water and fully submerged right up to the shoreline. A climate‑controlled, pressure‑resistant cabin keeps occupants or cargo dry, supporting prolonged underwater missions without the time limits of wet subs. The compact 45‑foot design is transportable and can be customized with various cabin layouts and payload options, delivering a versatile solution for both military and commercial subsea tasks.
Target Audience
Primary customers are naval and special‑operations forces, as well as commercial operators such as offshore survey, inspection, and rescue teams that require rapid surface‑to‑submerged capability.
Features
- Dual‑domain operation: turbocharged diesel engines for surface speed and battery‑powered propulsion for immediate dive capability
- Dry, climate‑controlled pressure‑resistant cabin that remains habitable during submersion
- Hyper‑ballasting system providing over 30,000 lb of lift for rapid submergence and operation in very shallow water
- Heavy‑lift central chassis allowing modular cabin configurations and payload customization
- On‑board recharge system that sustains repeated dives as long as the 500‑gallon fuel supply lasts
- Compact 45‑foot hull enabling easy transport, docking, and launch similar to conventional speedboats
