Gudgeon was the first American submarine to circumnavigate the globe; the navigator aboard this history making voyage was Lt. Leon Leroy Stine Jr., who died on January 30, 2018.

A Mare Island Naval Shipyard overhaul occupied the remainder of the year, and Gudgeon returned to Pearl Harbor 9 March 1955.

She sailed 21 Jul 1955, for the first of five WestPac tours, visiting Yokosuka, Formosa, Hong Kong, Manila, and Guam before returning to Pearl Harbor on 30 January 1956.

Three WestPac cruises, in 1959, 1961, and 1963, took it to Japan for exercises with the Seventh Fleet as well as to the US naval base at Subic Bay in the Philippine Islands and Hong Kong for liberty.

During 1983, Gudgeon was transferred by lease to Turkey and renamed TCG Hızırreis (S 342), named for Ottoman Admiral Kurtoğlu Hızır Reis.
