USS Buchanan (DD-484) was an American WWII destroyer. The keel for this unit was laid in February 1941, and the launch took place in November 1941. The total length of the ship at the time of launching was 106.15 meters and a width of 11 meters. The displacement reached approx. 1,650 tons, and the maximum speed reached approx. 37-38 knots. The armament at the time of the launch consisted of: four 127 mm guns, six 20 mm anti-aircraft guns and 533 mm torpedo tubes.
USS Buchanan (DD-484) was one of over 60 Gleaves-class destroyers. Units of this type were designed in the late 1930s based on the Sims class destroyers. Compared to their predecessors, they had slightly reinforced artillery weapons, but above all, a different structure of the engine room, which was to ensure a better chance of surviving the ship in the event of being hit by a torpedo or an aerial bomb. In general, however, both classes of destroyers (Sims and Gleaves) were similar in many respects. One of the Gleaves-class destroyers was just that USS Buchanan, which was built at the Federal Shipbuilding and Drydock Company in Kearny, NJ. The unit, almost immediately after entering service in March 1942, was sent to the Pacific. There she covered the American landing on Guadalcanal and Talagi in August 1942 and took part in the Battle of Savo Island, incl. saving survivors from damaged or sunken Allied cruisers. In October of the same year, the USS Buchanan took part in the Battle of Cape Esperance, and in November it was badly damaged in the initial phase of the Battle of Gudalcanal. In July 1943, the destroyer fought in a battle near the island of Kolombangara. The unit also took an active part in supporting the Iwo-Jima and Okinawa landings in 1945. The destroyer ended its participation in World War II with a presence in Tokyo Bay at the time of signing Japan's unconditional surrender in September 1945. The USS Buchanan was one of the most marked ships of the US Navy during World War II. In 1948, it was decommissioned, and a year later handed over to the Turkish Navy, where it served under the name Gelibolu until 1976.
