The second HMS Tarpon (N17) was a T-class submarine of the Royal Navy. She was laid down by Scotts, Greenock and launched in October 1939.


Tarpon had a short career, serving in the North Sea. She left Portsmouth on 5 April 1940 for Rosyth in company with HMS Severn. The following day they were ordered to Norway. On the 10th Tarpon was ordered to take up a new position. Tarpon was never heard from again. Post War German records showed that Tarpon had attacked the Q-ship Schiff 40/Schürbek, but her first torpedoes had missed. The Q-ship picked up the Tarpon on her sonar and her periscope was sighted. The ship dropped numerous depth charges in a sustained counterattack that went on most of the morning. Finally a pattern of depth charges brought wreckage to the surface. The Q-ship remained on the scene until 0500 the next morning until it became clear the submarine had been sunk. Tarpon was reported overdue on 22 April 1940.[2][3]
