USS Cook Inlet (AVP-36)

Cook Inlet departed San Diego, California, on 15 January 1945 and arrived at Pearl Harbor, Hawaii, on 21 January 1945. She tended seaplanes at Hilo, Hawaii, from 25 January 1945 to 31 January 1945.

Cook Inlet arrived off Saipan on 26 February 1945 to serve with the escort and patrol group based there, and from 2 March 1945 to 14 March 1945 was on an air-sea rescue station during the invasion of Iwo Jima. Cook Inlet rescued 27 survivors of downed bombers. She was still on duty at Iwo Jima when hostilities with Japan ended on 15 August 1945, bringing World War II to a close.

Cook Inlet received one battle star for World War II service.

Cook Inlet remained on duty off Iwo Jima until 29 November 1945, when she sailed to Jinsen, Korea, for duty as station tender. She then returned to the United States, calling at Iwo Jima and Pearl Harbor before reaching San Francisco, California, on 22 January 1946.

Cook Inlet was decommissioned and placed in reserve in the Pacific Reserve Fleet on 31 March 1946.

Cook Inlet's home port was Portland, Maine, throughout her Coast Guard career of almost 23 years. She served in the North Atlantic Ocean, where her primary duty was to serve on ocean stations to gather meteorological data. While on duty in one of these stations, she was required to patrol a 210-square-mile (544-square-kilometer) area for three weeks at a time, leaving the area only when physically relieved by another Coast Guard cutter or in the case of a dire emergency. While on station, she acted as an aircraft check point at the point of no return, a relay point for messages from ships and aircraft, a source of the latest weather information for passing aircraft, as a floating oceanographic laboratory, and as a search-and-rescue ship for downed aircraft and vessels in distress, and she engaged in law enforcement operations.

On 12 October 1953, Cook Inlet rendezvoused with the Coast Guard cutter USCGC Chambers (WDE-491) in the Atlantic to take a medical patient from Chambers which Chambers had evacuated the previous day from the merchant ship Neva West. She then transported that patient to medical facilities ashore.

Cook Inlet took part in the United States Coast Guard Academy cadet cruise of August 1965.

On 28 January 1966, Cook Inlet rescued survivors in of a swamped pleasure craft. Between 3 and 8 February 1966, she escorted the distressed Liberian merchant vessel Arion to Bermuda. On 8 April 1966, she assisted the burning Norwegian passenger-freighter Viking Princess, sending a fire and rescue party aboard Viking Princess to fight her fires; rushing from Guantanamo Bay, Cuba, in a three-hour voyage, the U.S. Navy frigate USS Wilkinson (DL-5) also assisted Viking Princess, taking 13 survivors of the ship aboard from the Republic of China merchant ship Chungking Victory and transporting them to Guantanamo Bay.

Cook Inlet was reclassified as a high endurance cutter and re-designated WHEC-384 on 1 May 1966. Her loan period from the Navy came to an end on 26 September 1966, when she was transferred permanently from the Navy to the Coast Guard.

On 8 January 1968, Cook Inlet evacuated a crewman in medical distress from the Swedish merchant ship California.

Cook Inlet was assigned to Coast Guard Squadron Three in South Vietnam on 2 July 1971. Coast Guard Squadron Three was tasked to operate in conjunction with U.S. Navy forces in Operation Market Time, the interdiction of North Vietnamese arms and munitions traffic along the coastline of South Vietnam during the Vietnam War. The squadron's other Vietnam War duties included fire support for ground forces, resupplying Coast Guard and Navy patrol boats, and search-and-rescue operations. Cook Inlet served in this capacity until 21 December 1971.

Cook Inlet earned two campaign stars for her Vietnam War service, for:

• Consolidation I 16 July 1971 – 9 August 1971, 27 August 1971 – 15 September 1971, 1 October 1971 – 24 October 1971, and 22 November 1971 – 30 November 1971
• Consolidation II 1 December 1971 – 15 December 1971

The Coast Guard decommissioned Cook Inlet in South Vietnam on 21 December 1971, the day her Vietnam War tour ended.
