OUR CAPABILITIES

MANNED SYSTEMS

MSubs has designed, built, and operated specialized submersibles supporting diver lock-out and long-endurance operations as scientific research vessels and military vessels since 1986.

UNMANNED SYSTEMS

MSubs’ Unmanned Underwater Vehicles (UUVs) hull designs are based on our manned submersibles, enabling most systems and components to be within the pressure hull.  This enables MSubs UUV’s to be maintained and replenished without recovery, reducing turnaround time.  UUVs can be operated manned or unmanned, using Submergence Group’s SUBNAVSYS integrated bridge system. MARTAC MANTAS hybrid USV’s offer Maritime Protection capabilities beyond human abilities.
