The Shallow Water Combat Submersible (SWCS) is a crewed
History
The SWCS program was initiated in 2008, after the cancellation of the ASDS, the anticipated replacement for the SEAL Delivery Vehicle.
In September 2018 the Defense Security Cooperation Agency notified Congress of the possible sale of 3 SWCSs to the United Kingdom for a total of $90 million.[5]
Design
The SWCS is 12 inches (30 cm) longer and 6 inches (15 cm) taller than its predecessor, the Mark 8 SDV.
Compared to the DCS it will serve alongside, the SWCS will be able to enter areas that the DCS cannot.[8]: 7 It will also be deployable from submarines, a capability that the DCS lacked as of 2015.[8]: 17
The SWCS's larger dimensions will require expanding the DDS to accommodate it.[15] The Navy plans to lengthen the DDS by 50 inches (1.3 m) and triple its weight capacity.[13]
