The (S351) NEMESIS Dry Combatant Submersible (DCS) is a swimmer lockout submersible capable of operating independently or from a host ship. Designed to answer the need for a long-range dry combat submersible, Nemesis incorporates many design innovations that improve overall capability, enhance vehicle and swimmers’ operational effectiveness. The submersible has three watertight sections; a forward compartment which is the transport compartment that houses up to eight swimmers or other payloads, an amidships swimmer lock-in/lock-out compartment, and an aft compartment that serves as the Pilot/Navigator operating station with a mature Command System. Nemesis’ innovative submersible design demonstrates MSubs ability to anticipate and rapidly respond to customer requirements.
