USS Sennett, 1947

Sennet (SS-408) was laid down on 8 March 1944 by the Portsmouth (N.H.) Navy Yard; launched on 6 June 1944; sponsored by Mrs. Roscoe W. Downs; and commissioned on 22 August 1944, Comdr. George E. Porter in command.

When the war ended in the Pacific, Sennet was assigned to the Atlantic Fleet and operated from New London, Conn. In June 1946, she was reassigned to Submarine Squadron 6 at Balboa, C.Z. From 10 December 1946 to 13 March 1947, Sennet participated in Operation “Highjump,” the third Byrd Antarctic Expedition.

Sennet operated from Balboa until 1949 when she was assigned to operate from Key West, Fla., as a unit of Submarine Squadron (SubRon) 12. The ship conducted training for submarine and antisubmarine personnel at Key West and Guantanamo Bay, Cuba. In 1951, Sennet was converted to a fleet snorkel submarine at the Philadelphia Naval Shipyard and returned to her homeport.

From 30 January 1955, until 1 August 1959, the submarine conducted training, local, and fleet operations with her squadron. On the latter day, Sennett was reassigned to SubRon 4 and stationed at Charleston, S.C. In November 1968, the submarine was found unfit for further Naval service. Sennet was struck from the Navy list on 2 December 1968. On 18 May 1973, her hulk was sold to Southern Scrap Material Co. Ltd., New Orleans, La.

Sennett received four battle stars for World War II service.
