THE EARLY YEARS 1945 - 1952
After routine fitting out was completed, USS Greene got underway on July 5, 1945, for Guantanamo Bay, Cuba for its initial shakedown training. Completing training on August 9, 1945, the ship reported for radar experiments off Fort Pierce, Florida. It was here that the ship celebrated the news of the Japanese surrender. Originally slated for duty with the Pacific Fleet, her assignment was changed to the U.S. Atlantic Fleet and USS Greene was assigned to Destroyer Squadron 68.
The primary role of USS Greene and the other ships of her class at the end of World War II was no longer defensive in nature. The ship was now primarily an offensive weapon. Relying on her five-inch , three-inch and anti-aircraft guns and torpedoes, her mission was now to conduct surface attacks, to provide naval shore bombardment and to screen carrier task forces from attack. Her secondary role was to support Hunter-Killer (HUK) Groups in anti-submarine warfare (ASW).
Operating from Norfolk, Virginia , as home port , USS Greene participated in operations with the U.S. Sixth Fleet in the Mediterranean Sea and with the U.S. Second (then Eighth) Fleet in the Caribbean Sea and North and South Atlantic Oceans. Of particular interest is that USS Greene and her sister USS Gearing (DD-710) were plane guards for the USS Roosevelt (CVA-42) in 1946 during the test flight of the first all jet engine plane to take off from a carrier. In early 1947, as a unit of Destroyer Unit 41, USS Greene departed for Montevideo, Uruguay and participated in the festivities accompanying the inauguration ceremony for President Beretta. On the return trip to the United States a visit was made to Rio de Janeiro, Brazil. On November 10, 1947, USS Greene sailed on the first of what would be many Mediterranean cruises that would be made over the next twenty-five years.
During 1948 and 1949 USS Greene twice sailed for duty with the Sixth Fleet in the Mediterranean. In late 1949 she joined other ships of Task Force 28 to lead an experimental cold weather cruise north of the Arctic Circle. The results of this cruise proved valuable in research on operating under severe cold weather conditions. USS Greene like other destroyers spent little time in home port. She constantly sailed the east coast and Caribbean waters providing services as a naval reserve training ship, schooling reservists, serving as a plane guard in carrier operations, exercising with large task groups, and standing watch against air and seaborne threats to the security of the United States. Sixth Fleet duty in the Mediterranean was again in the offing when USS Greene departed on January 19, 1951. After participating in combined fleet maneuvers, she returned to Norfolk, Virginia in June.
