Shallow Water Combat Submersible for SBS?

The elite Special Boat Service (SBS) could be getting some new transport. Shallow Water Combat Submersible (SWCS) is a mini-submarine that can carry 6 men for up to 100 miles. SWCS is equipped with sonar to assist detection and evasion of the enemy. The SWCS is being designed for the US Navy SEALs and could also be used for the SBS seeing as they already use the same system the Mark VIII, it is thought the mini-sub is being fast tracked for use in anti-piracy operations off Somalia.

Replacing the 70s vintage Mark VIII SDV SWCS is a lot more advanced though like the Mark VIII the hull will be flooded with water when in operation to negate the need for an airlock. It will have video imagery, passive sonar, and a submerged navigation system what uses pulse doppler sonar and motion detectors to calculate the sub's position exactly so it does not need to break to the surface to get a GPS fix.
