NSRS (NATO Submarine Rescue System) Case Study

NSRS (NATO Submarine Rescue System) Case Study


The NSRS (NATO Submarine Rescue System) is at the forefront of submarine rescue technology. It is rapidly mobilised and transported by air or road transport.

Deployment time on a MOSHIP is dramatically reduced by the system’s innovative fly-by-wire remote control system housed in a separate control module. The basic method of achieving this is by providing a closed circuit breathing system whereby the diver’s gas is returned to the surface and exhausted to the atmosphere rather than exhausting into the water.
