HMS Ambush, the second of the Astute Class of Royal Navy attack submarines, has officially joined its fleet on the Clyde.. The £1.6bn nuclear-powered 7,400-tonne vessel has been undergoing sea trials since arriving at its home port at Faslane in September and is is due to enter operational service later this year.

With luck, HMS Ambush will not share the problems of the first of the class, HMS Astute, which has been described as rustly, leaky and slow.  The Astute suffered from an embarrassing grounding, electrical and hydraulic failures, and a murder aboard ship.
