Bathyscaphe Trieste II

The Trieste II ( Service Name: DSV -1 Deep Submergence Vehicle for 1; German about: deep submersible vehicle 1) was an American bathyscaphe. It was the successor to the successful Trieste, which was bought by the U.S. Navy in 1958 and whose body was pressure reused. The original design has been greatly modified by the Naval Electronics Laboratory, San Diego and built at Mare Naval Shipyard Iceland. Upon completion in 1964, the Trieste II was transported over the Panama Canal to Boston.

Under the command of Lt. Comdr. John B Mooney, Jr, with the co- pilot Lt.. John H. Howland and Capt.. Frank Andrews, led the Trieste II dives in the area of the sunken submarine USS Thresher by. In September 1964, she discovered this wreckage that could be determined as part of the Thresher.

Between September 1964 and May 1966, the Trieste II in Iceland Mare Naval Shipyard has been greatly modified. However, it is unknown whether it has been used in this new shape. At the same time, a third configuration of the bathyscaphs was planned. This led to a new look for the Trieste II and included the installation of a new pressure hull.

Until September 1, 1969, the Trieste II was only listed as " equipment ". Only on this day it was put to the envelope number X -1 as the vehicle in service. On 1 June 1971, she was reclassified as DSV and was in the service of the Pacific Fleet until 1980.

Today, the Trieste II is exhibited as a museum ship in the Naval Undersea Museum in Keyport (Washington, USA).
