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 ...
Deepsea Challenger (DCV 1) was a 7.3-metre (24 ft) deep-diving submersible designed to reach the bottom of the Challenger Deep, the deepest-known point on Earth.On 26 March 2012, Canadian film director James Cameron piloted the craft to accomplish this goal in the second crewed dive reaching the Challenger Deep.
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]

The Challenger Deep is located in the Western Pacific Ocean near the island of Guam in the Mariana Trench, the deepest known part of an ocean on Earth, and the deepest known location on Earth. [5] The May 2009 dive by the Nereus achieved a depth of 10,902 metres (35,768 ft), making it the world's deepest-diving vehicle then in operation, and ...
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.
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.
Alvin, first of its ship class of deep submergence vehicle (DSV), was built to dive to 2,440 metres (8,010 ft). Each of the Alvin-class DSVs have different depth capabilities. However, Alvin is the only one seconded to the National Oceanic and Atmospheric Administration (NOAA), with the others staying with the United States Navy .
