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 ...
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 ...
General arrangement, showing the key features. Trieste was designed by the Swiss scientist Auguste Piccard, based on his previous experience with the bathyscaphe FNRS-2.The term bathyscaphe refers to its capacity to dive and manoeuvre untethered to a ship in contrast to a bathysphere, bathys being ancient Greek meaning "deep" and scaphe being a light, bowl-shaped boat.

The Shinkai 6500 (しんかい) is a crewed research submersible that can dive up to a depth of 6,500 metres (21,300 ft). It was completed in 1990. It was completed in 1990. The Shinkai 6500 is owned and run by the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) and it is launched from the support vessel Yokosuka .
In comparison to the earlier Deep Sea Warrior bathyscaphe Striver can dive more than twice as deep. In comparison to the ten-hour endurance of Deep Sea Warrior, Striver lasts for six hours. [4] [5] Striver can dive and surface much faster, [6] and its crew compartment is built of titanium alloy Ti62A, specially developed for use on Striver. [7]
an Indian under-development crewed deep-submergence vehicle intended to be utilised for deep sea exploration of rare minerals in the Indian Ocean. It is capable of diving down to a depth of 6,000 m. First uncrewed trial was conducted on 27 October 2021 where the 'personnel sphere' was lowered to a depth of 600 m, off the coast of Chennai. [28] [29]
In 2012, Cameron became the first person to solo pilot a sub to the world’s deepest point, Challenger Deep, in the Mariana Trench, 11km beneath the ocean’s surface.
A 1.7 m (5.6 ft) escape sphere was mounted on the forward hull. Access was through four 500 mm (20 in) hatches with one 600 mm (24 in) emergency escape hatch. Five view ports with 90° viewing angle in the forward sphere, three 120 mm (4.7 in) inside diameter for forward viewing and one 50 mm (2.0 in) inside diameter on each side. [1]
