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.

Submarines are cool and no one can deny that! The amount of complexity inside one of these is incredible and a visit to the Chatham Historic dockyard is a great opportunity to see the HMS Ocelot up close. (http://www.thedockyard.co.uk/)
A brief bit of history; the Ocelot was the last submarine commissioned at Chatham dockyard in the 1960s. Capable of carrying 69 men and a payload of 24 torpedoes; the Ocelot was used in clandestine missions until 1991 when it became obsolete against the new fleet of nuclear subs.
Engine Room delviering 6,000 shaft horsepower
It amazes me that anyone knew how to operate this thing with the number of dials, switches, levers and buttons throughout.
Pressure is a big deal underwater, capable of bursting lungs if you try to surface to quickly.
The torpedo room; need to emergency exit? It’ll take 4 hours due to the pressure!
Emergency air valves, you’ll need it…
Apart from the Ocelot there were a number of other sites including the HMS Cavalier and the HMS Gannet.
