From 1946 to late 1953, "Shea" was engaged in normal operations with the Atlantic Fleet. Assigned to Min-Div 2 and based at Charleston, South Carolina, she ranged the Atlantic seaboard and Caribbean Sea. This employment was interrupted late in 1950 by a Mediterranean cruise, during which she visited Trieste on a liaison mission with the British armed forces in the area. "Shea" returned to Charleston and the Atlantic Fleet on 1 February 1951 and remained so engaged until September 1953 when she reentered the Pacific.
