Gleaves- (Bristol-) class Buchanan was laid down with Aaron Ward at Federal Shipbuilding & Dry Dock Co., Kearny, New Jersey, 11 February 1941. The two ships were also launched on the same day, 22 November, and Buchanan commissioned 21 March 1942.
After shakedown, the “Buke” transited the Panama Canal and arrived in the South Pacific. Attached to Destroyer Squadron 12, her first tour included the entire Solomon Islands phase of the war:
Following a West Coast overhaul, her only one of the war, Buchanan supported the invasion of the Palaus in September–October 1944, screened carrier operations against enemy targets in the Philippines, Formosa and South China Sea areas in December 1944 and January 1945, supported the operations at Iwo Jima, February–March, and Okinawa March–May, and then screening strikes by the Fifth and Third Fleets against the Japanese home islands.
Buchanan’s final wartime assignment was at Tokyo Bay. In August 1945, she, Lansdowne and Lardner, the three DesRon 12 ships present, were assigned to escort Admiral Nimitz’s flagship South Dakota into Japanese waters. In the following days, Buchanan transported Adm. Nimitz and Adm. Halsey around the bay; then, on 2 September, she ferried Gen. MacArthur and his party to and from Missouri for the surrender ceremony. Throughout September, she continued to operate in support of the occupation effort before departing for the United States, where she arrived in October.
Decommissioned at Charleston, South Carolina, in May 1946, Buchanan remained in the reserve fleet for 2½ years. In December 1948, she was placed back in commission in preparation for transfer to Turkey. Recommissioned in 1949 as Gelibolu, she served as the Turkish Navy as until 1976.
