#torpedo – An investigation is under way after a 9ft–missile was fired from HMS Argyll at high security Plymouth nuclear submarine dockyard during a training drill this week. 

A Royal Navy spokesman said: "We can confirm an incident occurred onboard HMS Argyll on Wednesday, March 12, at 3.24pm, while the ship was alongside at Devonport Naval Base in Plymouth.

"During a training exercise, an inert Test Variant Torpedo (TVT) unexpectedly jettisoned onto the wharf. There was no explosion and no casualties.

A source said: "The torpedo came shooting out of the side of Argyll and flew through the air before going straight through a security fence.

"It's carried on going before hitting a storage container. If anyone was inside it they would have a had a nasty shock - the whole side of the container was stoved in.
