RNTR Arroachar was a torpedo testing centre opened in 1912 with the bulk of its activity occurring during WWII when approximately 12,565 torpedoes were launched into loch long.
The centre did not test ‘live’ rounds and was used solely to test the range of torpedos. Seven recovery boats were in action each day to recover the torpedos launched into the loch. Working torpedos were then transported to RNAD Coulport for war heading.
Submarines would often be pulled up alongside the jetty to conduct Discharge Weapon System Trials. RNTR Arroachar supplied torpedos required for the Submarine Commanders’ Course, on these days over 40 torpedos would be fired into the loch.
