Bathyscaphe Trieste before its only dive into the Mariana Trench The Trieste in 1958. A bathyscaphe (/ ˈ b æ θ ɪ ˌ s k eɪ f,-ˌ s k æ f /) is a free-diving, self-propelled deep-sea submersible, consisting of a crew cabin similar to a Bathysphere, but suspended below a float rather than from a surface cable, as in the classic Bathysphere design.
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.

Sea Pole class bathyscaphe is designed by the 702nd Research Institute of China Shipbuilding Industry Corporation.The general designer is Mr. Xu Huangnan (Chinese: 徐芑南), a professor of School of Naval Architecture, Ocean and Civil Engineering Archived 2009-04-27 at the Wayback Machine(Chinese: 船舶与海洋工程学院) of Shanghai Jiao Tong University (SHJTU), who also designed many ...
The Rainbowfish bathyscaphe is a second generation bathyscaphe designed to be able to dive to a depth of 11 km (6.8 mi), effectively covering 100% of the oceanic floor. . The general designer is Mr. Cui Weicheng (崔维成), who was the first deputy general designer of the first generation bathyscaphes Sea Pole and Jiaolo
a DSRV class of five ships built by the USSR and Russia. The titanium-hulled Priz class are capable of diving to 1,000 metres (0.62 mi). These mini-submarines can ferry up to 20 people for very brief periods of time (in case of a rescue mission) or operate submerged for two to three days with a regular crew of three to four specialists.
The 22-foot-long Titan takes around two hours to reach the ocean bed, where the Titanic sank in 1912 causing the deaths of 1,500 crew and passengers.
The original Trieste design was heavily modified by the Naval Electronics Laboratory in San Diego, California and built at the Mare Island Naval Shipyard. Trieste II incorporated the original Terni, Italian-built sphere used in Trieste, after it was made redundant by the new high-pressure sphere cast by the German Krupp Steelworks.
Emergency separation General layout. Alvin was designed as a replacement for bathyscaphes and other less maneuverable oceanographic vehicles. Its more nimble design was made possible in part by the development of syntactic foam, which is buoyant and yet strong enough to serve as a structural material at great depths.
