On 29 May, she stood out of Charleston on her way to participate in Operation "United Effort/Ocean Safari '83" which included operations in the Baltic Sea. During that tour of duty the warship also made port calls at Portsmouth, England, on two occasions, and at Malmo, Sweden, and Aalborg, Denmark, once each. "Aylwin" returned to Charleston on 25 July and stayed there until the beginning of September. The frigate put to sea again on 2 September and headed south for a four-week assignment in the Caribbean Sea that included calls at a number of tropical ports that include the Bahamas, St. Kitts, Antigua, Venezuela, and Colombia. Back in Charleston on 4 October, she spent the remainder of 1983 engaged in operations along the east coast.
