The Shallow Water Combat Submersible (SWCS) is a crewed submersible and a type of swimmer delivery vehicle that is planned to be used to deliver United States Navy SEALs and their equipment for special operations missions. It will replace the current Mark 8 SEAL Delivery Vehicle. The Navy planned to introduce the SWCS in 2018,[7] although "slippage in the development"[8] has delayed its introduction until 2019. In 2020, the U.S. Navy stated that it was undergoing sea trials and testing.[2][9] As of October 2018[update], two subs have been delivered to the Navy while another two were in production.[2] The SWCS will serve alongside the Dry Combat Submersible (DCS), a midget submarine with a dry interior being developed by Lockheed Martin as a replacement for the cancelled Advanced SEAL Delivery System (ASDS).[8]: 7
