USS Collett (DD-730) was a World War II-era Allen M. Sumner-class destroyer in the service of the U.S. Navy, named after Lieutenant Commander John A. Collett (1908–1942). Collett was launched 5 March 1944 by Bath Iron Works Corp., Bath, Maine; sponsored by Mrs. C. C. Baughman as proxy for Mrs. J. D. Collett; and commissioned at the Boston Navy Yard on 16 May 1944, Commander James D. Collett—brother of Lt.Cmdr. Collett—in command.
Collett returned to Empire waters with the carrier task force to screen during air raids on Honshū 25 February 1945, joined in the bombardment of Okino Daito Shima 2 March, and returned to screening during the air strikes on Kyūshū and southern Honshū of 18 to 20 March. From 23 March to 24 April, the force concentrated its strikes on Okinawa, invaded on 1 April. On 18 April Collett joined with four other destroyers and carrier aircraft to sink Japanese submarine I-56 in .
After replenishing at Ulithi, Collett rejoined TF 58 11 May 1945 for its final month of air strikes supporting the Okinawa operation, and from 10 July to 15 August sailed with the carriers as they flew their final series of heavy air attacks on the Japanese home islands. With her squadron, she swept through the Sagami Nada on 22 and 23 July, aiding in the sinking of several Japanese merchantmen. After patrol duty off Japan, and guarding the carriers as they flew air cover for the landing of occupation troops, Collett entered Tokyo Bay 14 September 1945, and 4 days later sailed for a west coast overhaul.
Her second tour of duty in the Korean war, from 18 June 1951 to 17 February 1952, found her screening TF 77 as it conducted air strikes on the Korean east coast, training with an antisubmarine group off Okinawa, patrolling in the Taiwan Straits, and conducting shore bombardments along the coast of Korea. Similar duty, aside from bombardment, was her assignment during her third tour, from 29 August 1952 to 9 April 1953.
From the close of the Korean war, Collett served in the Far East in between 1953 and 1959. Early in 1960 she began an extensive modernization, which continued until July 1960. On 19 July 1960, Collett collided with Ammen off Long Beach, California, killing 11 and injuring 20, all members of Ammen's crew. Despite a badly smashed bow, Collett made port under her own power, entering the Long Beach Naval Shipyard for extensive repairs. Her bow was removed and replaced with that of Seaman, an uncompleted destroyer in the Reserve Fleet. On 5 November 1960, Collett departed Long Beach for coastal operations, which continued intermittently for the remainder of the year.
In 1974, Collett and Mansfield (DD-728) were bought by Argentina as a supply of spare parts for other ships, and towed from San Diego to Puerto Belgrano. However, Collett was found to be in good enough condition to be worth rehabilitating. On 17 May 1977, she was commissioned in the Argentine Navy as ARA Piedra Buena (D-29), the fourth ship of that name. During the Falklands War, on 2 May 1982, the Piedra Buena was steaming in company with the cruiser ARA General Belgrano when the cruiser was sunk by the British attack submarine HMS Conqueror.
On 18 February 1985, Piedra Buena was decommissioned from and stricken from the ships' register. In November 1988, the ex-Piedra Buena was sunk in a naval missile exercise, by an MM38 missile fired by the newly-commissioned guided missile frigate ARA Espora (P-41).
