The maximum depth recorded during this record-setting dive was 10,908 metres (35,787 ft). [44] Measured by Cameron, at the moment of touchdown, the depth was 10,898 m (35,756 ft). It was the fourth-ever dive to the Challenger Deep and the second crewed dive (with a maximum recorded depth slightly less than that of Trieste 's 1960 dive). It was ...
This is the maximum depth at which a submarine is permitted to operate under normal peacetime circumstances, and is tested during sea trials.The test depth is set at two-thirds (0.66) of the design depth for United States Navy submarines, while the Royal Navy sets test depth at 4/7 (0.57) the design depth, and the German Navy sets it at exactly one-half (0.50) of design depth.
Oceanic trenches typically extend 3 to 4 km (1.9 to 2.5 mi) below the level of the surrounding oceanic floor. The greatest ocean depth to be sounded is in the Challenger Deep of the Mariana Trench, at a depth of 10,911 m (35,798 ft) below sea level.

The Japanese robotic deep-sea probe Kaikō broke the depth record for uncrewed probes when it reached close to the surveyed bottom of the Challenger Deep. Created by the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) , it was one of the few uncrewed deep-sea probes in operation that could dive deeper than 6,000 metres (20,000 ft).
BI reported in September that the General Staff Main Directorate for Deep Sea ... The unit operates a small fleet of deep-sea submarines capable of operating at a depth of around 2,500 meters and ...
Project 210, Project 10831 [4] [5] or AS-31 [5] [3] (Russian: АС-31), nicknamed Losharik (Russian: Лошарик, IPA: [lɐˈʂarʲɪk]), is a Russian deep-diving nuclear powered submarine. On 1 July 2019, a fire broke out on the vessel while it was taking underwater measurements of the sea floor in Russian territorial waters.
On 7 May 2019, Vescovo and Jamieson, in Limiting Factor, made the first human-occupied deep submersible dive to the bottom of the Sirena Deep, the third deepest point in the ocean, about 128 mi (206 km) northeast of Challenger Deep. They spent 176 minutes at the bottom, and among the samples they retrieved was a piece of mantle rock from the ...
