HMS Tuna (N94) was a T-class submarine of the Royal Navy. She was laid down by Scotts, Greenock and launched on the 10 May 1940.

[edit] Career

Tuna had a relatively active career, serving in the North Sea and off the French and Scandinavian coasts.

She sunk the German merchant Tirrana on the 1 September 1940. The Tirrana had previously been captured by the German armed merchant cruiser Atlantis, in the Indian Ocean. She also torpedoed and sank the German catapult ship Ostmark and the French tug Chassiron. She fired upon and sank the German submarine U-644 and attacked the German submarine U-302 and the Italian submarine Brin as well as two unidentified submarine contacts, all unsuccessfully. Another attack on the German tanker Benno , formerly the Norwegian Ole Jacob, which had also been captured earlier by the Atlantis, also failed.[1]

Tuna was also used to deliver the "Cockleshell Heroes" to the mouth of the Gironde for their daring raid on Bordeaux, France, in which six German ships were mined. The raid was called Operation Frankton, and only two of the 12 men returned.

[edit] Post war

Tuna survived the war and was sold to be broken up for scrap on 19 December 1945, a job carried out at Briton Ferry from June 1946.
