USS Buchanan (DDG-14) was a guided missile destroyer in service with the United States Navy from 1962 to 1991. She was sunk as a target in 2000.

History Buchanan was named for Admiral Franklin Buchanan and was laid down by Todd-Pacific Shipbuilding at Seattle, Washington on 23 April 1959, launched on 11 May 1960, and commissioned on 7 February 1962. She was commissioned by the Commandant, Thirteenth Naval District, Rear Admiral George C. Towner.

1962–1965 After completing her final outfitting at Puget Sound Naval Shipyard, Bremerton, Washington, Buchanan got underway for Long Beach Naval Shipyard, California, on 25 March 1962. She moored at her new homeport of San Diego, on 5 April. The destroyer reported for duty and was assigned to serve as the flagship of Destroyer Squadron 15, Cruiser-Destroyer Flotilla 7, United States First Fleet. On 25 May 1962 the destroyer put to sea for Pearl Harbor, Hawaii, for her shakedown cruise.

The Buchanan arrived at Pearl Harbor on 30 May and participated in the dedication of the USS Arizona Memorial. She returned to San Diego on 6 June to continue her shakedown before proceeding to Puget Sound on 17 September 1962. Buchanan returned to San Diego on 5 November 1962, where she was placed on unrestricted availability with the fleet.

The Buchanan began operating in 1963 in the area off Southern California before departing for her first deployment to the western Pacific. She put out for Pearl Harbor with the destroyer on 4 April. Once at Pearl Harbor, she was placed in drydock for a few days (9–14 April).

The Buchanan returned to sea in company with Somers on 18 April and operated with Task Force 77.3.1, consisting of attack aircraft carrier , radar picket destroyers and , for the 21st commemoration of the Battle of the Coral Sea at Sydney, Australia. As the task force neared Sydney, Buchanan detached on 27 April and steamed independently for Melbourne, Australia. After the festivities in Sydney concluded, she rendezvoused with Coral Sea and the newly formed Task Group 77.6 en route to Guam on 13 May.

Over the next two months, the Buchanan accompanied TF 77.6 to Guam (22–26 May), Naval Station Subic Bay (27 May–1 June) and Manila, Philippines (25–29 June), Hong Kong (13–20 June), and Yokosuka (9–15 July) and Sasebo, Japan (22–29 July 1963). On 5 August, she tested her Tartar missiles in the Okinawa Missile Range before putting into Okinawa (9–12 August), Beppu (22–26), and Iwakuni, Japan (26–26 August). Afterward she returned to Yokosuka (7–21 September) for upkeep, giving her crew shore leave. The Buchanan returned to Sasebo (2–3 October) and Yokosuka (9–16 October) before putting into Subic Bay on 21 October. She departed Subic Bay to make a port call at Hong Kong on 29 October.

While at Hong Kong, the destroyer's rest was abruptly cut short. On 1 November 1963, members of the Republic of Vietnam military staged a coup against the regime of President Ngo Dinh Diem. In response, the U.S. Navy deployed a flotilla off the mouth of the Mekong River for the potential evacuation of American citizens and service members. As part of this operation, The Buchanan departed Hong Kong escorting the aircraft carrier with Southerland and on 2 November. The coup had ended with assassination of Diệm, his brother Ngȏ Ðình Nhu, and Col. Hồ Tần Quyền, the commander of the Vietnamese navy. With reassurance from the new leadership under General Dương Văn Minh that order had been restored and alliances unchanged, the Navy reduced its presence off of South Vietnam.

The Buchanan departed the area on 5 November for Subic Bay. On 15 November 1963 she left Subic Bay for San Diego arriving on 27 November. After the holidays, Buchanan operated out of San Diego before moving to the San Francisco Naval Shipyard at Hunters Point, California (USA), for overhaul (7 May–22 September). Several days after emerging from overhaul, she rejoined Destroyer Squadron 15 to participate in fleet exercise "Union Square" (28 September – 1 October 1964).

Vietnam War On 5 January 1965, Buchanan departed with destroyers , and for Pearl Harbor. She left for Subic Bay on 13 January with , , , , and Chevalier, putting into their destination on 26 January. On 1 February Buchanan began her tour of duty patrolling, providing escort and plane guard services in the South China Sea. As the situation worsened in Southeast Asia, President Lyndon B. Johnson began increasing the number of American troops in South Vietnam. On 8 March 1965 the 9th Marine Expeditionary Brigade landed at Da Nang.

In between operations, Buchanan visited Yokosuka (28 April–7 May, 18–26 June, and 23–26 July), Hong Kong (9–13 June and 16–19 July), Subic Bay (14 June), and Okinawa (28 June). On 27 July 1965 Buchanan set course for the United States. She stopped at Pearl Harbor for a few days (2–3 August) before mooring at San Diego on 9 August. In mid-September, the destroyer entered Long Beach for overhaul (16 September–11 November) then spent the rest of the year conducting local operations. For her time in the South China Sea, Buchanan was awarded the Armed Services Expeditionary Forces Medal for supporting air strike operations over Vietnam.

During the early months of 1966, Buchanan operated out of her homeport conducting routine operations in the eastern Pacific. During April the destroyer participated in the fleet exercise "Gray Ghost" (12–22 April 1966). In June she was steaming for the western Pacific with Black and Southerland for another six-month deployment (11 June–21 December). On 1 July, Buchanan operated as a plane guard in Dixie Station, off the Mekong Delta, for the aircraft carrier as her aircraft executed air strikes in South Vietnam. Buchanan then moved north for operations in Yankee Station off Da Nang and the coast of North Vietnam (7–21 July). She broke from her combat operations to serve as the flagship of the United States Seventh Fleet during a port visit to Bangkok, Thailand, on 25–29 July 1966. Over the next several months, Buchanan alternated her operations between Yankee and Dixie stations. Wrapping up combat duty, she put into Hong Kong for a few days' rest (21–26 November) before working her way home via Okinawa (28–29 November), Yokosuka (1–4 December), and Pearl Harbor (15 December). She put into San Diego on 21 December 1966 where she remained until shifting to Long Beach Naval Shipyard for overhaul (15 March–5 August 1967), returning to San Diego for sea trials, refresher training for her crew, and local operations.

1967 collision While underway in a column formation with Southerland on the night of 14 September 1967 Buchanan collided with fishing vessel Holiday. The civilian craft claimed that the destroyer was at fault for the collision and that the Navy was culpable for the resulting damages. An ensuing investigation determined that Buchanan was the vessel with the right of way and that Holiday bore the burden to avoid the collision. Lookouts on the destroyer also indicated in subsequent interviews that there was no one in the fishing boat's wheel house at the time of the collision. The sailors' accounts also reported bright lights on the stern of Holiday and seeing crew members working on deck, perhaps preparing bait.

Although all indications exonerated Buchanan, the ship's crew clearly made errors that contributed to the accident. It was revealed that the officer of the deck lacked the experience and training to properly handle the situation. Lt. Victor J. Monteleon was qualified to command the ship while she operated independently but not certified to operate in formation with other ships. At the time of the accident, the sea was calm with visibility estimated to have been better than 12 km. The destroyer was steaming in a darkened condition with her navigation lights burning. As the vessels converged, Buchanans Combat Information Center properly and continually reported Holiday's position, speed and bearing. Monteleon served as the junior officer of the deck, and Lt. Thomas S. Ballard, USNR, were also tracking Holiday visually from the port wing. The two officers discussed changing course but took no action. Once Monteleon realized that a collision was imminent, he ordered the conn to right full rudder with all engines ahead at full speed.

The Navy investigation into the collision determined that, although the destroyer had the right of way, Monteleon had committed several grievous errors. The most serious was the failure to notify his commanding officer, Capt. William A. Spencer, of the situation. According to Spencer's night orders, he was to be notified of any visual or radar contacts within of the ship. Additionally, Monteleon failed to take action to avoid the collision. He also did not sound a danger signal, an option provided to him in accordance to the rules of the road. As the legalities were being sorted out, Buchanan went about her schedule. On 3 November she entered Hunters Point for alterations until 20 December 1967. Buchanan spent the rest of the year in San Diego on holiday leave and preparing for another deployment.

Buchanan departed San Diego for Southeast Asia on 27 January 1968. During her deployment, she participated in Operation Sea Dragon (25 October 1966 – 31 October 1968) to disrupt the flow of supplies going from North Vietnam to support communist operations in South Vietnam. She also provided naval gunfire support (NGFS) to ground troops fighting in South Vietnam, most notably during the first phase of the Tet Offensive and the Battle of Huế (30 January – 3 March 1968). During one tour providing NGFS, Buchanan came under fire from an enemy shore battery on 29 May. The ship sustained shrapnel damage to the heating and cooling system of the No. 1 cell of her ASROC launcher. Several of her antennae and electrical cables were damaged but no crewmembers were harmed. In response, Buchanan silenced the enemy position with 20 rounds from her 5-inch guns.

In addition to her gunnery operations, Buchanan also served as plane guard in Gulf of Tonkin for (5–11 and 14–18 March), , and (15–17 May), in addition to and (20 June–1 July 1968). Buchanan retired to Subic Bay (9–17 June) for battle damage repairs after another tour providing NGFS to the I Corps Tactical Zone (30 May–7 June). During her time in the western Pacific, Buchanan was afforded rest and recreation at Hong Kong (7–11 May, 16–21 July) and Yokosuka, Japan (26–28 July) before setting a course home, stopping at Midway Atoll on 2 August and Pearl Harbor on 5 August along the way. Once back in San Diego on 11 August 1968, her sailors were granted post-deployment leave for four weeks.

On 18 March 1969 Buchanan was once again underway for the western Pacific with Bon Homme Richard, , Chevalier, and Southerland. During this deployment, the destroyer once again served as a plane guard for Ticonderoga in the Gulf of Tonkin (8–24 May) and provided NGFS for troops in the I and II Corps Tactical Zones. Her guns supported the men of the 3rd Marine Infantry Regiment and the 173rd Airborne Brigade in the area of Da Nang (16 June–16 July 1969). During these operations Buchanan sent more than five thousand 127 mm shells downrange toward the enemy. Buchanan made several port calls for upkeep and rest for her weary crewmen at Subic Bay (30 April–8 May, 2–4 September), Sasebo (28 May–8 June, 5–16 August, 25–30 August) and Hong Kong (18–24 July) before steaming for San Diego on 4 September 1969. Once back at her home port on 18 September, Buchanan underwent a survey and inspection (24–26 November), ending the year working with destroyer tender .
