UK In Action: Submarine on the Clyde

Royal Navy submarine HMS Astute sails up the Clyde estuary into her home port of Faslane, Scotland for the first time following the journey from Barrow-in-Furness shipyard. She is flying a Blue Government Service Ensign. The Astute submarine has the latest stealth technology, a world-beating sonar system and is armed with 38 torpedoes and missiles - more than any previous Royal Navy submarine. She will be able to circumnavigate the globe while submerged, and advanced nuclear technology means that she will never need to be refuelled. Astute will be followed in due course by her sister submarines Ambush, Artful and Audacious. These four comprise the first of the expected seven submarines in the Astute Class. The Astute class will carry the potent Spearfish Heavyweight torpedo which can destroy submarines or surface ships, and Tomahawk cruise missiles that can hit inland targets with pinpoint accuracy. The boats will have 50 per cent more firepower than the existing Trafalgar class submarines they will succeed in service.
