Upon completion of filming, Whitehurst operated off Oahu until September, when she was ordered to Seattle, Washington, for duty as a training ship with the 13th Naval District making an extended cruise to Guaymas, Mexico, in November 1957.
After an overhaul from February to April 1958, Whitehurst returned to training duties, becoming a Group II ASW reserve ship in July.
