330-PSA-312-62 (USN 711146): This is the design of the new 10-ton, two-man undersea research vehicle to be constructed by General Mills, Inc., for Navy oceanographic research.  The submersible, which can be carried aboard and operated from the Navy’s existing oceanographic ships, will be operated by Woods Hole Oceanographic Institution as part of a research program supported by the Office of Naval Research.  The 20-foot undersea craft, capable of depths of 6,000 feet which allows it to explore the Continental Shelf, will be completed in the summer of 1963 at a cost of $575,000.  It will have a maximum speed of six knots, an endurance of 24 hours and a maximum range of 30 miles.  The two-man crew and 1,200 pounds of scientific instrumentation will be contained in a spherical cabin or pressure hull similar to the steel sphere of the Navy’s bathyscaph Trieste.  Surrounded the sphere will be a free-flooding, cylindrical-shaped outside skin, including a five-foot conning tower, fabricated of reinforced fiberglass.  The steel for the spherical pressure hull will be 1 ½ inch thick high-strength HY 100 steel.  Photograph released October 12, 1962.  (2015/10/13).
