Alvin 771k 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 inch thick high-strength HY 100 steel. USN photo # USN 711146, courtesy of the National Museum of the U.S. Navy, via

Alvin 1.07k The Navy research submarine, Alvin (DSV-2) was operated by the Woods Hole Oceanographic Research Institution for the Office of Naval Research. The craft is 29 feet long and weighs 11 tons. It has a molded fiber-glass hull, which houses 8,400 pound sphere, made of one-inch thick steel, in which the two men crew will ride. The sphere can be released in an emergency and will float to the surface. Alvin is expected to have continuous speed of four knots, six knots in short bursts and a maximum range of 25 miles. Alvin is named for Allyn C. Vine, a Woods Hole Oceanographic Research doctor, who was greatly responsible for the submarine's creation. Photograph released 24 June 1964.
