"US urgently buys miniature submarines for Navy special forces"

From https://dzen.ru. | [2020?].

"US Special Operations Command Press Service ( USSOCOM ) released a report yesterday, which announced the acceleration of the operational test program of the latest miniature submarine Dry Combat Submersible ( DCS ) with its early adoption. Based on the requirements of the command, the new submarines 'should be ready to conduct real combat operations with a high risk' by May 29."

"Submarine details are classified, but it is known that DCS is a development of the S351 Nemesis project developed by MSub for the UK Navy."

"The displacement of the 12-meter [39 feet] submarine is 30 tons, and the working depth of the dive varies between 330-360 feet ( 100-110 meters ). As a power plant, several electric motors are used that provide a maximum range of 66 nautical miles ( 122 km ). In addition to a crew of 2 people, DCS can transport up to eight special forces and about a ton of cargo."

"The submersible has three watertight sections; a forward compartment which is the transport compartment that houses up to eight swimmers or other payloads, an amidships swimmer lock-in/lock-out compartment, and an aft compartment that serves as the Pilot/Navigator operating station"
