A short film clip (3-min 10-sec) circa. 1960 featuring the Royal Navy submarine HMS Narwhal.
HMS Narwhal (S03) was a Porpoise-class diesel-electric submarine launched in 1957. She was built by Vickers-Armstrongs at Barrow-in-Furness (now BAE Systems Submarine Solutions and still building submarines for the Royal Navy). Equipped with 8 21-inch torpedo tubes (6 bow, 2 stern) the Porpoise-class carried a load of 24 Mk VIII "point-and-shoot" or Mark 24 Tigerfish guided torpedoes.
Narwhal had a 26-years service with the Royal Navy. She was withdrawn from active service in 1974 and remained in reserve until 1980 when she was deliberately sunk in Weymouth Bay during a submarine salvage exercise. She was later raised and sunk again as a target, approx. 15-miles south of Falmouth, in 1983. According to 'Lost Patrols: Submarine Wrecks of the English Channel' (Innes McCartney, 2003) her wreck is divable.
The submarine depot ship is HMS Adamant (A164). She was depot ship for 3rd Submarine Squadron at Rothesay Bay (1954-1957) and then at Gare Loch (1959-1962). She became depot ship for 2nd Submarine Squadron at Devonport in 1964 and paid off in 1966. Adamant was broken up at Inverkeithing in 1970.
