I have performed repairs on a research submarine owned by the US Navy. The sub was in dry-dock at the time of repairs. It was also undergoing modifications to its hull, as huge steel plates were being added. I was told by Navy officials that it was the "World's deepest diving sub."
I am not able to disclose any additional details, as the Navy considers it to be Classified Information. However, with regard to another person's (very informative and detailed) answer, you may want to "add" some depth to those figures, since another sub has exceeded those figures even prior to the hull-strengthening modifications.

while i wont dispute any of the excellent answers so far provided (or give them thumbs down, which i expect to recieve a few of), one thing that muct be considered on questions like this:
CLASSIFIED.

if the US navy has submarines capable of going 25,000 feet down, most of the world will not know that until something new and even more classified is going 30,000 feet down.....


"other means"
i assume you mean methods that actually tell us something..... cause i could go out and drop a rock into the deepest place in the world and reach the farthest spot possible, but it wouldnt tell me anything at all.
manned vessels will always have limits as they must provide protection for the crew. but unmanned has no limits beyond what the equipment itself can handle, new technology comes out daily.

The deepest anyone has ever reached, either in the world's oceans or otherwise, ie: even taking deep mining and offshore drilling operations into account, was in a very highly specialised vessel designed by a father and son team from Switzerland: Auguste and Jaques Piccard.

" ... a new type of probe called a bathyscaphe (meaning 'deep boat'). Christened Triest, after the Italian city in which it was built, the new device manoeuvred independently, though it did little more than just go up and down." ¹

(The much earlier 'bathysphere', designed by Otis Barton in 1930, in which he descended with his partner, Charles Beebe, to a depth of 183 metres and later, in 1934, to over 900 metres thus beginning modern deep ocean exploration, merely dangled on a long cable.)

"... in January 1960 Jaques Piccard and Lt. Don Walsh [ ... ] sank slowly to the bottom of the ocean's deepest canyon, the Mariana Trench, some 400 kilometres off Guam in the western Pacific [ ... ] It took just under four hours to fall 10,918 metres, or almost 7 miles." ¹

Wikipedia concurs (almost): "more accurate measurements made during 1995 have found the Challenger Deep to be slightly shallower, at 10,911 metres" as (again almost) it does with the dive-time: "4 hours and 48 minutes" And adds: "3 hours, 15 minutes" for the ascent. ²

According to NASA ³, as well as many other reputable sources, Apollo 17 (by way of typical example) launched on December 7, 1972 at almost exactly 12:33 a.m., and made lunar landing, some four days and twenty hours later, on December 11 at almost exactly 7:55 p.m. (Though, for obvious reasons, slower on the way out, faster coming back!)
