Two ships of the United States Navy have been named Duluth, after the city of Duluth, Minnesota.
USS Duluth (CL-87) was a United States Navy Cleveland-class light cruiser.
She was launched 13 January 1944 by Newport News Shipbuilding & Dry Dock Company, Newport News, Virginia; sponsored by Mrs. E. H. Hatch, wife of the Mayor of Duluth, Minnesota; and commissioned 18 September 1944, Captain Donald Roderick Osborn, Jr., US Naval Academy class of 1920, in command.
From 14 December 1944 to 2 March 1945, Duluth served as a training cruiser at Newport, Rhode Island. After brief overhaul at Norfolk, she sailed 7 April for the Pacific, arriving at Pearl Harbor 29 April. On 8 May, she got underway to join the 5th Fleet and rendezvoused with the fast carriers on 27 May. Severe structural damage to her bow suffered in a typhoon 5 June forced her to return to Guam for repairs, but she rejoined TF 38 on 21 July to screen during the final air strikes on the Japanese homeland which continued until the end of the war.
From 24 August 1945 until she entered Tokyo Bay 16 September, Duluth operated with TF 38 which was providing radar picket and combat air patrol for transport aircraft flying occupation forces into Japan. On 1 October, Duluth sailed for the United States, arriving at Seattle 19 October for Navy Day celebrations.
USS Duluth (LPD-6), an Austin-class amphibious transport dock, is the second ship of the United States Navy named for the city in Minnesota.
Duluth was laid down on 18 December 1963 by the New York Naval Shipyard. She was launched on 14 August 1965 and commissioned on 18 December 1965. She was the last ship to be launched from the Brooklyn Navy Yard before it was closed.
The ship sailed to Danang, Republic of Vietnam, in May 1965 to operate with Amphibious Ready Group, U.S. 7th Fleet in the Vietnam War. On 15 June 1966, a Sikorsky H-34 from HC-4 made the first helicopter landing on board.
In 1967, from the months of May until November the Duluth operated with Amphibious Ready Group, Seventh Fleet, in South China Sea. Conducted amphibious landing operations Bear Claw and Beacon Guide at Hue (7 June), Chu Lai (12 June), Cue Viet ( 3, 27 July), and Phu Loc (21 July). Took part in Operations Beacon Gate at Song Cua Dai and Chu Lai ( 7–16 August) and Beacon Point off Thua Thien province. The LPD then steamed off Quang Nam and Quang Tin provinces during Operation Ballistic Charge ( 16–28 September). After refitting at Subic Bay, Duluth participated in helicopter-centered Operation Bastion Hill near Cua Viet (10 October – 1 November). Following vehicle ferry operations from Subic early in the month, the LPD steamed to Hong Kong, arriving there 17 November.
