United States Pacific Fleet - Post 1945

Post 1945

The Pacific Fleet took part in Operation Magic Carpet, the return of U.S. servicemen, after the end of the Second World War. The organization of the Pacific Fleet in January 1947 is shown in Hal M. Friedman's Arguing over the American Lake: Bureaucracy and Rivalry in the U.S. Pacific, 1945-1947.

Since 1950 the Pacific Fleet has been involved in the Korean War, the Vietnam War, the two Taiwan Straits Crises, and a number of other operations including the Mayaguez Incident of 1975, as well as post-Vietnam related operations such as Operation New Arrivals. The RIMPAC exercise series began in 1971.

In 1984, the Secretaries of Transportation and Navy signed a Memorandum of Agreement which created the Maritime Defense Zones (MDZ). These MDZs, one on each coast, are echelon three Navy commands under Fleet CINCS. The Pacific MDZ has responsibility for coastal defense 0-200 Nautical Miles around the U.S. West Coast, Alaska, Aleutian Islands, and Hawaii during times of hostility. On 1 October 1990, Commander U.S. Naval Forces Alaska (COMUSNAVAK) was established as the Naval Component Commander to Commander, Alaskan Command (COMALCOM). Since its inception, COMUSNAVAK has grown to become responsible for coordinating all Navy activity in the Alaska and Aleutian area, for detailed planning and coordination for the Naval portion of the Joint and Combined EXERCISE Northern Edge, and coordinates high-visibility U.S. Navy ship visits throughout Alaska in support of public relations and recruiting initiatives.

The very large PACEX '89 in the North Pacific involved the USN, Canadian Navy, Japanese Maritime Self-Defence Force, and ROK Navy. At the end of Exercise PACEX '89 a 54 ship formation was assembled for photos. It included the flagship, USS Blue Ridge (LCC-19), the USS Enterprise (CVN-65) Battle Group, the USS Carl Vinson (CVN-70) Battle Group, two battleship surface action groups formed around the USS New Jersey (BB-62) and USS Missouri (BB-63), and a Japanese Maritime Self-Defence Force task force.

Other operations undertaken since include participation in the Alaskan Oil Spill Joint Task Force, including participation of Commander, Amphibious Group Three, as deputy CJTF. This was the defence response to the Exxon Valdez oil spill of March 1989. Also, the Pacific Fleet was involved in Joint Task Force Philippines during the December 1989 coup attempt there, which involved two carrier battle groups, USS Midway and USS Enterprise-with their associated air wings operating in the Philippine Sea, chopped to JTF Philippines. During the operations, the carriers maintained deck alerts and 24-hour coverage of Manila with E-2C aircraft.

Around September 10, 1990, USS Princeton (CG-59) and the USS Reuben James (FFG-57) visited Vladivostok. This marked the first United States Navy visit to the Soviet Union's Pacific port of Vladivostok since before World War II. Before the visit was completed, the crew received word that their Pacific cruise was canceled. They returned to Long Beach and joined the USS Ranger Battle Group preparing to deploy to the Persian Gulf.

During Operation Fiery Vigil in June 1991, the following vessels participated in the sealift phase of the evacuation: the Lincoln battle group (COMCARGRU 3 embarked): USS Abraham Lincoln (CVN-72), USS Long Beach (CGN-9), USS Lake Champlain, USS Merrill, USS Gary, USS Ingraham, USS Roanoke, Amphibious Ready Group Alpha (COMPHIBRON 3 embarked): USS Peleliu (LHA-5), USS Cleveland, USS Comstock, USS Bristol County, and a large number of other vessels: USS Midway, USS Curts, USS Rodney M. Davis, USS Thach, USS Arkansas, USS McClusky, USS St. Louis, USS San Bernardino, MV 1st Lt Lummus, MV American Condor, USS Niagara Falls, USNS Ponchatoula, USNS Passumpsic, USNS Hassayampa, USS Haleakala, USNS Spica, USS Cape Cod. (CNA, 1994, 113) Further operations included JTF Marianas (August–September 1992) and JTF Hawaii (September–October 1992).

Other contingency operation after 1991 included Operation Sea Angel (Bangladesh relief) (led by Commander III Marine Expeditionary Force), Operation Eastern Exit, and involvement in the Somali Civil War - 'Restore Hope'. During 'Restore Hope,' Navy command arrangements underwent a number of changes during the operation. At the start, the principal naval forces were the Ranger battle group (with Commander, Carrier Group One embarked on USS Ranger (CV-61) as Commander, Naval Forces), the Kitty Hawk battle group, an amphibious task unit including USS Tripoli (LPH-10), USS Juneau, USS Rushmore, and MV Lummus, and three ships from MPSRON TWO (MV Anderson, MV Bonnyman, and MV Phillips). Other events led to the departure of the carriers and, as a result, Commander, Naval Forces responsibilities devolved first to Commander, Carrier Group Three, on Kitty Hawk, and thence to Commander, Amphibious Group Three. Finally Commander, Amphibious Squadron 3 became COMNAVFOR on 15 January with the departure of COMPHIGRU THREE after the completion of the MPF offload. (CNA, 1994, 168)

In 1995 Pacific Fleet surface ships were reshuffled. Effective Oct. 1, 1995 the U.S. Pacific Fleet's surface ships were to be reorganized into six core battle groups and eight destroyer squadrons. Permanent core battle groups were to include a battle group commander, aircraft carrier, carrier air wing and at least two cruisers.

• Commander Cruiser-Destroyer Group 1/USS Constellation Battle Group: USS Lake Erie and USS Chosin
• ComCruDesGru 3/USS Carl Vinson Battle Group: USS Shiloh, USS California and USS Arkansas
• ComCruDesGru 5/USS Kitty Hawk Battle Group: USS Cowpens and USS Antietam
• Commander Carrier Group 7 (ComCarGru 7)/USS Nimitz Battle Group: USS Port Royal and USS Lake Champlain
• ComCar Gru 3/USS Abraham Lincoln Battle Group: USS Princeton and USS Chancellorsville
• Commander Carrier Group Five/USS Independence Battle Group: USS Bunker Hill and USS Mobile Bay

In 1996 two carrier battle groups were sent to the Taiwan area during the Third Taiwan Straits Crisis. Later ships of the Pacific Fleet, notably the Ticonderoga-class cruiser USS Mobile Bay (CG-53) provided support to the entry of INTERFET in East Timor in 1999.

Between 25–27 March 2006, Carrier Strike Group Nine participated in a series of anti-submarine warfare exercises (ASW) in Hawaiian waters while en route to the U.S. Seventh Fleet's area of responsibility. In addition to the strike group, the exercise also included the nuclear-powered attack submarines Seawolf, Cheyenne, Greeneville, Tucson, and Pasadena, as well as land-based P-3 Orion aircraft from Commander Patrol and Reconnaissance Wing 2 and associated patrol squadrons VP-4, VP-9, and VP-47.

As of 2011, the Pacific Fleet consists of the numbered Third and Seventh Fleets, as well as Naval Air Force, Pacific; Commander, Naval Surface Forces Pacific; Naval Submarine Force, Pacific; and other commands. The naval shore commands Commander Naval Forces Korea; Commander Naval Forces Japan; and Commander Naval Forces Marianas are also under the authority of the Pacific Fleet.
