Dry Combat Submersible

The Dry Combat Submersible (DCS) is a midget submarine delivered to USSOCOM by Lockheed Martin. Lockheed Martin were nominated as the prime contractor with Submergence Group as the sub contractor. 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. As the name suggests, the Dry Combat Submersible has a dry interior, enabling longer mission durations in colder water. The DCS is designated the S351 Nemesis. Lockheed Martin and the Submergence Group were awarded the $166 million, 5-year contract to develop and build three DCSs in June 2016. By 2018, the total spent on the submersibles rose to $236 million.
