The Johnston went down after giving all it had in the 1944 Battle off Samar that turned back the Japanese Navy's Center Force as it steamed toward the landing at Leyte Gulf. Where she went down is close on 25,000 feet deep. The wreck was found in 2019 but it was too deep for the ROV to investigate. This recent visit was by a manned submersible.

It is just a blurb, but one thing came out: two of the Johnston's 5"-38 turrets were still firing when she went down, and the torpedoes were all gone, fired off. The wreck is still in good shape.
