THE second of the Royal Navy's potent new Astute Class attack submarines, sailed into Faslane last week to begin sea trials.

The 7,400 tonne submarine HMS Ambush sailed from the shipyard in Barrow-in-Furness in Cumbria, where she was built.

Minister for Defence Equipment, Support and Technology Philip Dunne said: "Ambush's arrival at her home port to begin her sea trials marks a key milestone in the Astute Class submarine programme and is testament to the skills of those involved in the UK's world class submarine building industry.

"Ambush is an immensely powerful and advanced vessel that will deliver an important capability to the Royal Navy giving it the versatility and technical excellence needed to operate successfully across the globe." The seven Astute Class boats planned for the Royal Navy are the most advanced and powerful attack submarines Britain has ever sent to sea.

The boat's Commanding Officer, Commander Peter Green, said: "It was very satisfying bringing Ambush into her home port for the first time after initial sea trials.

"The ship's company and I are now looking forward to putting her through her paces over the coming months, ensuring that she is one step closer to being deployed on operations."
