Yamagumo (山雲, Mountain Cloud)[1] was the sixth of ten Asashio-class destroyers built for the Imperial Japanese Navy in the mid-1930s under the Circle Two Supplementary Naval Expansion Program (Maru Ni Keikaku).
In February 1943, while attempting to escort Tatsuta Maru to Truk, she was unable to prevent the former luxury liner from being torpedoed by the submarine USS Tarpon with the loss of 1,400 lives just east-southeast of Mikurajima.
The 42 survivors were rescued and taken as prisoners-of-war (POWs), then were transferred to the escort carrier Chūyō, until she was sunk by the submarine USS Sailfish, in which 20 out of 21 went down with the ship.
She was escort for the tanker Kokuyo Maru in January, and made three additional troop transport runs in the Solomon Islands area in February.
Yamagumo's wreck was discovered along with sister Michishio on 27 November 2017 by Microsoft co-founder Paul Allen's research ship RV Petrel.
Both wrecks were heavily encrusted with marine growth, which combined with their close proximity, made it impossible to distinguish the two ships.
