HMS Stonehenge (P232)

HMS Stonehenge was an S class submarine of the Royal Navy, and part of the third group built of that class. She was built by Cammell Laird and launched on 23 March 1943.

She served in the Pacific, where she sank the Japanese merchant vessel Koryo Maru No.2 and the Japanese auxiliary minelayer Choko Maru. She left Trincomalee to patrol in the northern part of the Malacca Straits on 25 February 1944. She was reported missing after failing to arrive at Ceylon on 20 March as expected. It is not known for sure what caused her sinking, but a mine was considered to be the most likely explanation.
