Trieste II bathyscaphe. US Navy Trieste II (DSV-1) bathyscaphe at sea being used to train naval officers and enlisted men to pilot the Navy's new deep submergence rescue vessels (DSRV) and other advanced small submersibles. A bathyscaphe is a free-diving self-propelled deep-sea submersible that uses a pressurise cabin suspended below a float. The original version of this deep-sea submersible, Trieste I, was designed in 1953 by the Swiss physicist Auguste Piccard. It was used to descend to the deepest known part of the Earth's oceans; a point known as Challenger Deep in The Marianas Trench, with Lieutenant Don Walsh and Jacques Piccard on board. It was retired in 1964, and its original pressure sphere was reused in its successor, the Trieste II, which was launched in 1964. Photographed on 23rd January 1960.
