1955-1957
1955–1957: Gibraltar, North Atlantic, and South America
From 2 May to 4 June 1955 she escorted replacements for the 6th Fleet to Gibraltar, then returned to anti-submarine evaluation and training in the western Atlantic and Caribbean, broken by a three-week patrol in the North Atlantic during the November 1956 Suez crisis. With Destroyer Squadron 24 she made an extended training cruise to South America from early January to late March 1957, visiting ports in Brazil, Argentina, and Uruguay between antisubmarine exercises with various Latin American navies. She returned to the Mediterranean from August to December 1957, also serving in the Red Sea during this deployment

Intensified operations in Vietnam called her with other ships of Destroyer Squadron 20 and they left Newport on 4 October for Panama and Yokosuka, arriving on 10 November. As they had in Korea, her guns supported troops ashore, first driving back Viet Cong attempting to overrun Vũng Tàu on 21 November. After four months on the gunline giving major service in the struggle to keep South Vietnam free, Norris completed a circumnavigation by returning via Suez to Newport, arriving on 25 April 1967.
Following east coast and Caribbean operations, Norris returned to the Mediterranean on 29 April 1968 for duty through the summer months. Returning to Newport in the fall, she deployed again from 9 May through December 1969. Into 1970 she continued on rotation between the 2nd Fleet and 6th Fleet.
