The Royal Navy has completed a four-day trial of the NATO Submarine Rescue System in Scotland, testing the alliance’s ability to respond to a distressed submarine.

The exercise, held in Fort William between 23 and 27 March, brought together military and civilian personnel from the Royal Navy, Submarine Delivery Agency and JFD Ltd, alongside French and Norwegian partners. The NSRS is a tri-national capability jointly owned by the UK, France and Norway and is designed to rescue submariners from disabled submarines anywhere in the world.
