"Eugene A. Greene" operated along the east coast and in the Caribbean on shakedown training, acting as plane guard during the qualification of pilots in carrier operations, and training men for the crews of new destroyers. From her home port in Norfolk, Virginia, she sailed to Guantanamo Bay for training early in 1947, and on 13 February sailed in a task group bound for Montevideo, Uruguay, to participate in the festivities accompanying the inauguration of Uruguay's President Berres. The group also paid a good will visit to Rio de Janeiro before returning to Norfolk on 31 March.
