The Royal Navy needed this like a hole in the head with the week that is in it. The HMS Astute, the newest and most modern submarine in the Royal Navy, has run aground off the Isle of Skye. Looking at the video attached to the BBC report is gas. The Captain describing how high-tech it is, fly by wire technology, fibre optic persicopes etc, the Captain even pointing out that there are no 'steering wheels' needed to manovere the sub as it is all done at the push of a button - gas altogether. You could not make it up.
