Armament

HMS Truculent was a British submarine of the third group of the T-class. She was built as P315 by Vickers Armstrong, Barrow, and launched on 12 September 1942. She sank nine enemy vessels.

The submarine was funded by donations from the town of Glossop in Derbyshire, whose population raised £175,000 in 1942-3 to fund warships.

Truculent struck a Swedish oil tanker outside the mouth of the Medway in January 1950, and sank, with the loss of 64 men. The number was unusually high, as the submarine was ferrying workers in addition to the crew. In March 1950, the wreck was towed to the destined nearby dockyard then sold for scrap.

Regional navigation rules thereafter mandated a Truculent Light a panoramic white light on the bow of submarines moving under their own power.
