Ulua & Tusk138kUlua (SS-428) & Tusk (SS-426) being built at the Cramp Shipbuilding Co. in Philadelphia on 7/2/45. The Ulua has not received her superstructure main deck or bridge. The Tusk is just about complete.
Diesel intakes (induction) are visible on board the Ulua. They trunk up into the main induction just abaft the conning tower pressure vessel. The starboard branch feeds the forward engines, the port branch, whose 22-in pipe is visible under the flat boards, feeds the after engines. When snorkels were installed postwar, their intakes connected to the main induction visible here. Exhaust piping is also visible.
The bow of the Turbot (SS-427) is just visible behind the stern of the Ulua.

Tusk103kDamage aboard the Tusk (SS-426) following collision with a surface vessel in February 1947.
During my cruise we were doing maneuvers in the Atlantic near the African coast and collided with the Hospital Ship Consolation (AH-15) while coming up to periscope depth, 60 feet. We suffered extensive damage and could not submerge. Consequently, we had to travel on the surface through a hurricane back to home port in Philadelphia, where the Tusk was repaired and retrofitted to the Guppy class.

Tusk352kHer duty with the Submarine School in New London continued until the middle of 1951 when she was assigned once more to Submarine Development Group 2. That assignment, punctuated by regular exercises with the fleet, continued until the summer of 1952 when she returned to an operational unit, Submarine Squadron (SubRon) 10. Normal east coast duty out of New London lasted until late in the year at which time Tusk (SS-426) was deployed to the Mediterranean for a six-month tour with the 6th Fleet.
She is seen here on 1 August 1952.

Tusk89kThe Tusk (SS-426), with BQR-4 wrapped around fore part of sail. This photo was taken in Long Island Sound in April 1963. We had the BQR-4 temporary installation in front of the sail installed in Philadelphia in the fall of 1962. We also had the clam-shell after deck installed at the same yard period. We lost one section of the clam-shell around the after engine-room hatch at sea in March 1963. The picture shows the temporary plating while the new section of clam-shell was being fabricated.Text i.d. courtesy of Gary Parker, Photo courtesy of John Hummel, USN (Retired).

Tolling The Boats 669k Active duty and veteran submariners stand together at the 29th annual "Tolling The Boats" Memorial Service held at the World War II National Submarine Memorial-West, Naval Weapons Station Seal Beach, Calif. 29 May 2006. The ceremony honored members of the Silent Service who gave their lives during World War II and the Cold War for their country and the cause of freedom.
On 25 August 1949 while steaming through a gale off the coast of Norway, Cochino (SS-345) suffered an explosion in one of her batteries. Tusk (SS-426) rushed to the aid of the stricken submarine, providing medical supplies for Cochino's injured by way of life rafts. One such raft capsized in heavy seas sending a Cochino officer and a civilian employee of the Bureau of Ships into the icy Arctic waters. Both were recovered, but during the administration of artificial respiration on board Tusk, another wave broke over her deck washing away the civilian and 11 Tusk crewmen.
