Through two cruises to the Caribbean in the summer of 1949, "Charles R. Ware" aided in the training of members of the Naval Reserve, then took part in a large-scale Arctic operation before preparing for a 1950 tour with the 6th Fleet in the Mediterranean. Her 1951 tour was highlighted by operations with ships of the Royal Hellenic Navy. Following her 1953 tour, she conducted antisubmarine warfare exercises with British ships off Northern Ireland, calling then at ports in Ireland, Germany, Norway, Denmark, and Belgium. Later that year she took part in exercises with the aircraft carrier off Narragansett Bay.
