330-PSA-276-63 (USN 711389):  Artist’s conception of Trieste II – a streamlined version of the Navy’s bathyscaph Trieste is scheduled to begin tests off the California coast in January 1964,  Lieutenant D.L. Keach, USN, Officer-in-Charge of the vessel then said.  The renovated Trieste II, built by the Mare Island Naval Shipyard, will have increased speed and endurance, and decreased draft.  The operating sphere in the $375,000 Trieste II is the 13 feet aft of the bow.  Keach said this would allow the bathyscaph to get closer to areas during research.   Photograph released November 21, 1963. Note, Trieste II served from 1969 to 1980.  She was reclassified to DSV-1 in June 1971. Trieste II is now a museum ship at the Naval Undersea Museum, Keyport, Washington. (2015/10/27).
