The Shallow Water Combat Submersible (SWCS), also known as the Mark 11 SEAL Delivery Vehicle (SDV Mk 11), is a crewed, wet (free-flooding) submersible that serves as a swimmer delivery vehicle for special-operations missions by United States Navy SEALs. Designed to replace the Mark 8 SEAL Delivery Vehicle (SDV Mk 8) on a 1-to-1 basis, Teledyne was awarded a contract to deliver 10 units for a cost of $179 million. The first two ships were delivered in 2018, with the last units planned for delivery in 2022.[7] The SWCS will serve alongside the pressurized Dry Combat Submersible (DCS), a midget submarine developed by Lockheed Martin to replace the cancelled Advanced SEAL Delivery System (ASDS).[8]
