A TORPEDO Range was operational on Loch Long from 1912 to 1986, and the abandoned Admiralty buildings, pier and slipway remained visible on the west shore of the loch, opposite Arrochar, until 2007, when the site was destroyed by fire and demolished.
Originally an Admiralty facility, the range (pictured right circa 1950) became the Royal Naval Torpedo Testing Station and Range, referred to variously as the Loch Long Torpedo Range and the Arrochar Torpedo Range.
