1944

Cassin Young arrived at Pearl Harbor 19 March 1944 to complete her training before sailing on to Manus, where she joined the massive Fast Carrier Task Force (then called TF 58, at other times called TF 38, depending on whether the overall organization was called 5th Fleet or 3rd Fleet). On 28 April, this force sortied for air attacks on Japanese strongholds at Truk, Woleai, Satawan, and Ponape, during which Cassin Young operated as a picket ship, assigned to warn her group of possible enemy counterattack.

She returned to Majuro, and then Pearl Harbor for further training before reporting to Eniwetok on 11 June to join the screen of escort carriers assigned to covering duty in the invasion of Saipan four days later. In addition to radar picket and screening duty, she was also called upon for inshore fire support. As the battle for Saipan raged ashore, escort carriers of Cassin Young's group launched attacks on the island, as well as sorties to neutralize enemy air fields on Tinian, Rota, and Guam. Similar operations supporting the subsequent assaults on Tinian and Guam claimed the services of Cassin Young until 13 August, when she returned to Eniwetok to replenish.

Cassin Young in 1944

Between 29 August and 2 October 1944, Cassin Young guarded the carriers of Task Group 38.3 as strikes were flown from their decks to hit targets on Palau, Mindanao, and Luzon in support of the assault on the Palaus, stepping-stone to the Philippines. Only four days after her return from this mission to Ulithi, Cassin Young sailed on 6 October with the same force on duty in the accelerated schedule for the Philippines assault. First on the schedule were air strikes on Okinawa, Luzon, and Formosa; these led to the furious Formosa Air Battle of 10 to 13 October, during which the Japanese tried to destroy the carrier strength of the imposing TF 38. On 14 October, the cruiser Reno was struck by a kamikaze, which wounded five of Cassin Young's men with machine gun fire. Cassin Young aided in shooting down several aircraft in this attack.

On 18 October 1944, TF 38 took position east of Luzon to launch strikes immobilizing enemy air fields there in preparation for the assault on Leyte two days later. After standing by to render support if called upon during the initial landings, Cassin Young's group began to search for the enemy forces known to be moving toward Leyte Gulf on 23 October, and next day moved in toward San Bernardino Strait, ready to launch strikes. In the most vigorous and successful air attack mounted by the Japanese during the Leyte operation, at 09:38 on 24 October, an enemy bomb struck the aircraft carrier Princeton, and Cassin Young rejoined TG 38.3 for the dash northward to attack the Japanese Northern Force. This developed on 25 October into the Battle off Cape Engaño, a series of air strikes in which four Japanese carriers and a destroyer were sunk.

1945

Cassin Young continued operations in support of the Leyte conquest, as her carriers continued to range widely, striking at enemy bases on Okinawa, Formosa, and Luzon. With Ulithi as her base, the destroyer screened carriers during the January 1945 South China Sea raid as their aircraft pounded away at Formosa, Luzon, Camranh Bay, Hong Kong, Canton, and the Nansei Shoto in their support for the assault on Luzon. A brief overhaul at Ulithi prepared her for the operations supporting the invasion of Iwo Jima with air strikes on Honshu and Okinawa, the bombardment of Parece Vela, and screening off Iwo Jima itself during the initial assault on 19 February.

1946

Cassin Young cleared Okinawa 8 August and headed home for repairs. Arriving home in San Pedro, California she was fully repaired, and then decommissioned and placed in reserve in San Diego on 28 May 1946.^[4]

1951–1960

Recommissioned 8 September 1951, she cleared San Diego on 4 January 1952 for her new home port, Newport, Rhode Island. In September 1952 she entered Dry Dock #1 in the Boston Navy Yard for the first of four major overhauls she would undergo in this shipyard. At this time the ship was updated to its current configuration. Two Hedgehog anti-submarine (ASW) launchers and two torpedo carriages for the Mark 32 torpedo were added, with one 21 inch (533 mm) quintuple torpedo tube mount removed. Also, four 40 mm Bofors twin mounts were replaced by two quadruple mounts. The forward pole mast was replaced by a tripod mast to accommodate improved radar and electronics systems. Local operations and refresher training in the Caribbean preceded a period of antisubmarine exercises off Florida from 7 May to 12 June 1953. Her first tour of duty with the 6th Fleet in the Mediterranean took place from 16 September to 30 November 1953. After another period of local operations, and exercises in the Caribbean Sea early in 1954, she cleared Newport on 3 May for a round-the-world cruise, which included exercises with the 7th Fleet in the western Pacific, patrols off Korea, and good-will visits to Far Eastern and Mediterranean ports. She returned to Newport on 28 November 1954. Her operations from that time until 1960 included training exercises in the Caribbean and off the eastern seaboard as well as tours of duty in the Mediterranean in 1956, winter 1956–57, and 1959, and a round of visits to ports of northern Europe in 1958. During that last overseas deployment an issue was discovered with her rudder that put her into dry dock in France. At that point the repair costs outweighed retaining the aging ship. Consequently, on 6 February 1960 she arrived at Norfolk Naval Shipyard to be decommissioned. The ship was put into long-term storage at the Philadelphia Naval Inactive Ship Maintenance Facility 29 April 1960.^[4]

Cassin Young arriving in Boston, 1978

1974–present

Cassin Young was struck from the Naval Vessel Register on 1 December 1974. The US Navy has permanently loaned Cassin Young to the National Park Service, to be preserved as a floating memorial ship berthed at the Boston Navy Yard, part of the Boston National Historical Park (BNHP) in Boston, Massachusetts, across from Constitution. She arrived on 15 June 1978 and was opened to the public in 1981. The ship is maintained and operated by the National Park Service^[4] and Cassin Young Volunteers.^[5] She was listed on the National Register of Historic Places and designated a National Historic Landmark in 1986, as a well-preserved example of the Fletcher-class destroyer, the most numerous class of destroyer produced by the United States during World War II.^[1][6]

In late July 2010, Cassin Young closed to the public in preparation for dry-docking. On 9 August 2010, she was moved into Historic Dry Dock #1 in BNHP for the first time in 30 years for some much needed repairs to her hull. On 4 September 2012, the ship was closed to the public to allow contractors to make final repairs to the hull. She returned to her position at Pier 1 on 14 May 2013. On 4 June 2013, she was moved to the Boston Harbor Shipyard and Marina in East Boston while repairs were made to her berth in Charlestown. By September 2013, she had returned to her museum berth.

Three other Fletcher-class ships are preserved as memorials:

• USS The Sullivans (DD-537) at Buffalo, New York
• USS Kidd (DD-661) at Baton Rouge, Louisiana
• Greek destroyer Velos (D16), former USS Charrette (DD-581), at Thessaloniki, Greece
