Sortieing with the Fast Carrier Task Force (then 3rd Fleet's TF 38, later 5th Fleet's TF 58) on 10 December 1944 for air strikes on Luzon, Cushing weathered the typhoon of 18 December 1944, and rescued survivors of less fortunate ships before returning to Ulithi on 24 December for storm repairs. She re-joined the task force on 1 January 1945 for air strikes on Formosa, Indo-China, China coast, and the Philippines until 28 January 1945.
Joining TF 58 for the strikes on the Japanese home islands, Cushing served as radar picket ship at the launching point and successfully directed the destruction of many Japanese aircraft trying to break through to attack the carriers. She screened the carriers for the pre-invasion strikes on Iwo Jima and Okinawa, and participated in "softening-up" bombardment of Okinawa. Serving as radar picket ship during the Battle of Okinawa, she provided fighter direction which accounted for many Japanese aircraft. After replenishing at Leyte in June, she rejoined the carriers for strikes on the Tokyo area until the end of the war. Anchoring in Sagami Wan on 27 August 1945, she served as harbor entrance control vessel for the occupation forces until sailing for home. Cushing returned home to Bremerton on 20 November 1945, and was placed out of commission, in reserve, at Long Beach on 3 February 1947.
Approx 20–23 December 1944, Cushing operated independently while rescuing some downed aviators. There were two notable incidents during this period. First there was the Betty, a twin-engined Japanese bomber. The Cushing lobbed some VT rounds at her, about 20,000 yards (18,000 m) (max range) to the west. The Betty, apparently damaged, came towards her, fishtailing to avoid heavy anti-aircraft artillery, when she was downed just off the stern of the Cushing, caused most likely by her 20 millimetres (0.79 in) rounds. It was possibly an early attempt at suicide attack. There was also a torpedo fired at the Cushing from a submarine, but it was detected by Sonar so that Cushing could turn and avoid.
1951 – 1960
Recommissioned on 17 August 1951, Cushing sailed from Long Beach on 15 November and arrived at Norfolk on 30 November to join the Atlantic Fleet. She conducted exercises in the North Atlantic and in the Caribbean, and cleared Norfolk on 7 January 1953 to join TF 77 off Korea for duty as plane guard. On 2 and 3 June she fired in the bombardment of Hodo Pando, North Korea. She visited Manila, Singapore, Colombo, Aden, Piraeus, Genoa, Cannes, and Algiers, before returning to Norfolk on 22 August from this cruise around the world. She cruised the east coast in anti-submarine exercises and reserve training, and in 1954 sailed to the Mediterranean for duty. Transferred to the Pacific Fleet, she arrived at Long Beach on 26 January 1955.
In tours of duty in the Far East in 1955, 1956, 1957–58, and 1959–60 Cushing served as plane guard and joined in hunter-killer exercises with TF 77, patrolled in the Taiwan Straits, and visited various ports strengthening national ties in the President Dwight D. Eisenhower's "People to People" program. While "stateside" she operated along the west coast in anti-submarine and anti-aircraft warfare exercises, and midshipmen and reserve training. Cushing's home port was changed to Charleston, South Carolina, in October 1960, and the destroyer sailed to the east coast. Cushing was again placed out of commission, in reserve, at Norfolk, Va., on 8 November 1960.
Cushing was loaned to Brazil 20 July 1961. She served in the Brazilian Navy as Paraná (D29). Paraná was struck on 1 August 1973, and broken up for scrap in February 1982.
