The Dry Combat Submersible (DCS) is a midget submarine delivered to USSOCOM by Lockheed Martin.

DCS is designed for use by the United States Navy SEALs for insertion on special operations missions.

It will replace the canceled Advanced SEAL Delivery System and will serve alongside the Shallow Water Combat Submersible.

[3] Lockheed Martin and the Submergence Group were awarded the $166 million, 5-year contract to develop and build three DCSs in June 2016.

[5] Unlike its predecessor, the Dry Combat Submersible will be deployed from surface ships rather than from larger submarines.

[6] The DCS' main advantage over its predecessors is its dry environment, which enables SEALs to undertake longer missions in colder water and be more combat-ready when they deploy.

[7] Another advantage is that the SEALs can communicate more easily in the DCS than in previous wet submarines, where they had to rely on intercoms and could not see each other.
