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 ...
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]
General arrangement, showing the key features.

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.
Jiaolong (simplified Chinese: 蛟龙号; traditional Chinese: 蛟龍號; pinyin: jiāolóng hào; lit. 'flood dragon') is a Chinese crewed deep-sea research submersible that can dive to a depth of over 7,000 metres (23,000 ft), developed from the Sea Pole-class bathyscaphe.
In comparison to the earlier Deep Sea Warrior bathyscaphe that was 95% domestically built, Striver is 96.5% domestic, [4] [5] [clarification needed] but can dive more than twice as deep. A significant portion of the onboard equipment has to be allocated to support the dive.
The New Submersible. The new submersible will be known as the Triton 4000/2 Abyssal Explorer. The 4000 in the name refers to the depth it can reach, which is slightly more than where the Titanic ...
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 .
