Included in these latter visits was a stop at Saigon 24 to 28 October for the Republic of Vietnam’s Independence anniversary celebrations.

Remaining on the west coast until late 1965, the guided-missile frigate underwent a 5½ month overhaul, 1 May 1965 to 20 October 1965, followed by test and training exercises and a demonstration of her antisubmarine warfare capabilities before members of the United States-Canadian Military Cooperation Committee 9 December 1965.

A contract to dismantle Mahan was issued in January 2003 to Bethlehem Steel-Sparrows Point of Baltimore, Md to dismantle Mahan. Mahan was repossessed for a third time after Bethlehem Steel went out of business and a new contract was issued to dismantle Mahan on 30 September 2003 to Metro Machine of Philadelphia, Pa for $3,000,000.
