With increased power and a new streamlined shape, "Chivo" returned to duty with the Atlantic Fleet in July 1951, resuming anti-submarine warfare (ASW) training operations with surface ships as well as maintaining proficiency in anti-shipping and mine warfare. These drills and exercises took place mainly off Key West and Guantanamo Bay. This regular training continued until 19 April 1952 when "Chivo" sailed for a short cruise with the 6th Fleet in the Mediterranean, visiting Augusta, Sicily; Cannes and Marseille, France; and Naples, Italy; before returning home via the Azores in June.
