USS Hart (DD-594) was a Fletcher-class destroyer of the United States Navy. She was launched on 25 September 1944 and commissioned on 4 November 1944. Walter Daniel Coleman was her captain from 21 March 1944.
Her shakedown took her along the California coast. In that period she joined the oiler Kaskaskia for trials of taking on fuel while both ships held high speed. Between 12 and 23 December she refueled at sea about fifty times, under shifting weather and sea conditions, and the exercises yielded practical guidance for a task the fleet had to perform constantly. That working-up period closed on 31 January 1945.
On 19 February 1945 she set out for Pearl Harbor. From 27 February through 3 March she stayed with the carrier Intrepid, covering gunnery practice and flight operations. On 5 March she went on toward Ulithi and arrived on 16 March. She remained with the fleet in the western Pacific through the spring and summer, and she was still in service when Japan surrendered on 15 August 1945. Her World War II service brought two battle stars.
She was then attached to a force newly gathered for North China duty. On 5 September 1945 she sailed in support of Army occupation troops landing at Jinsen, Korea. Mined water lay along the route, and the formation worked through it. In the harbor, boarding parties from Hart went onto Japanese merchant ships to inspect them and disarm them. After that she escorted Cruiser Division 6 while the cruisers made a show of strength off the China coast. In the months that followed she assisted as American Marines went ashore, and she called at Port Arthur, Tsingtao, and Taku.
The destroyer left for the United States on 9 February 1946. She was decommissioned on 31 May 1946 and laid up in reserve at Long Beach, California. The Navy later shifted her to Mare Island Naval Shipyard, and after that to Stockton, California.
On 15 April 1973 her name was removed from the Naval Vessel Register. She was sold for scrap on 3 December 1973, and the hull was broken up. She had survived the war, and that sale ended her service.
