A shipyard in Groton is holding a ceremony to commemorate the 60th anniversary of the keel-laying for USS Nautilus, the first nuclear-powered submarine.
It was on June 14 in 1952 that President Harry Truman officiated at the milestone for the submarine at the Electric Boat shipyard.
People involved with the Nautilus including the Navy's one-time project officer for the sub and a former shipyard employee who worked on the torpedo tube doors are expected to participate in the ceremony Thursday.
The Nautilus became the first vessel to cross the North Pole beneath the ice cap in 1958 and it was decommissioned in 1980.
It is now part of the U.S. Navy Submarine Force Museum in Groton.
