The Royal Navy's HMS Astute, the world's most advanced submarine, ran aground in familiar waters during an exercise off the Isle of Skye.
The accident is particularly embarrassing as it involves a new state-of-the art vessel, the largest British nuclear-powered attack submarine ever built for the navy. It cost £1.2bn and is equipped with the latest stealth and sonar technology, making it difficult to detect under the sea.
Causes of the incident are likely to cause human error. No details currently available, but the images of the sub stuck on the sea bed make it worth keeping the reference.
