Bathyscaphe Trieste (1958-1963)



Trieste, a deep-diving research bathyscaphe, was launched in 1953 near Naples, Italy, by the Swiss scientist Auguste Piccard. After several years of operations in the Mediterranean, she was purchased by the U.S. Navy. Transported to San Diego, California, in 1958, she conducted tests in the Pacific during the next several years, including a dive to the deepest part of the ocean in January 1960. In 1963, she went to the Atlantic to search for the lost submarine USS Thresher (SSN 593). Trieste was taken out of service soon after completing that mission and is now on exhibit at the Navy Museum, at the Washington Navy Yard, Washington, DC. Read More (DANFS)
