HMS Edinburgh (16), a Town-class light cruiser, was scuttled in the Barents Sea on 2 May 1942 while carrying 5 tons of Soviet gold. 431 of 465 bars were recovered 39 years later at 800 ft depth. “The salvage of the century.” 1941 [1381 x 663]

The salvage wasn't run by a navy or a corporation. A Yorkshire-born ex-diver named Keith Jessop spent years convincing the British government to even let him try (the wreck was a declared war grave). His team then lived at 800ft pressure for weeks, cutting through the cruiser's armored hull directly above the bullion room.
