Last updated: May 18, 2018 at 18:05 pm
The Deepsea Challenger (DCV 1) is capable of reaching the bottom of the Challenger Deep 10,994 m (36,070 ft). The 7.3-m (24 ft) submersible piloted by James Cameron was the second manned vehicle to touch the deepest known point on the planet in 2012. The Japanese research submersible Shinkai 6500 has reached a depth of 6,526 m (21,411 ft) in the Japan Trench. Russia’s Mir I and Mir II submersibles have a maximum operating depth of 6,000 m (20,000 ft). France’s Nautile also has a maximum operating depth of 6,000 m (20,000 ft). Both of the Mir submersibles have made several dives to the wreck of the RMS Titanic.
