During the summer of 1940, as part of the U.S. response to Japanese expansionism, the fleet was instructed to take an "advanced" position at Pearl Harbor, Hawaii. Admiral James O. Richardson, the fleet's commander, strongly opposed long-term basing at Pearl Harbor, feeling that it would leave the fleet vulnerable to Japanese attack, and personally protested the move in Washington, D.C. Political considerations were thought sufficiently important that he was relieved by Admiral Husband E. Kimmel, who was in command at the time of the attack on Pearl Harbor. The Pacific Fleet was formally recreated on 1 February 1941, when General Order 143 split the United States Fleet into separate Atlantic, Pacific, and Asiatic Fleets.
When the attack took place, all three carriers were absent – Saratoga was in San Diego collecting her air group following a major refit, Enterprise was en route back to Hawaii following a mission to deliver aircraft to Wake Island, while Lexington had just departed on a similar mission to Midway.
The Amphibious Force was formally known as Commander, Amphibious Forces, Pacific Fleet (ComPhibPac). On 7 December 1941 the Amphibious Force comprised the Army's 3rd Infantry Division at Fort Lewis, under Army operational control, the 2nd Marine Division, the 2nd Marine Aircraft Wing, the 2nd Defense Battalion (see Marine defense battalions), and a depot.[6] One of PhibPac's subordinate commands during World War II was Transports, Amphibious Force, Pacific Fleet, or TransPhibPac. The commander of TransPhibPac was known as ComTransPhibPac. In addition to the ships assigned directly to the Pacific Fleet, Destroyer Division 80, consisting of the destroyers Schley, Chew, Ward and Allen, was assigned directly to the Fourteenth Naval District for the defence of the base and the fleet.
In December 1941, the fleet consisted of nine battleships, three aircraft carriers, 12 heavy cruisers, eight light cruisers, 50 destroyers, 33 submarines, and 100 patrol bombers.[citation needed] This was approximately the fleet's strength at the time of the Japanese attack on Pearl Harbor. That day, the Japanese Combined Fleet carried out the attack on Pearl Harbor, drawing the United States into World War II in the Pacific. The Pacific Fleet's Battle Line took the brunt of the attack, with two battleships destroyed, two salvageable but requiring lengthy reconstruction, and four more lightly to moderately damaged, forcing the U.S. Navy to rely primarily on aircraft carriers and submarines for many months afterward.
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.[8]
On 7 March 1984, the Secretaries of Transportation and Navy signed a Memorandum of Agreement which created the Maritime Defense Zones (MDZ).[9] The Pacific MDZ is an echelon three Navy command under the Commander U.S. Pacific Fleet. The Pacific MDZ has responsibility for coastal defense up to 200 nautical miles (370 km; 230 mi) around the U.S. West Coast, 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.
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.[11]
Around 10 September 1990,[12]USS Princeton and USS Reuben James 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.
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 as Commander, Naval Forces), the Kitty Hawk battle group, an amphibious task unit including USS Tripoli, 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.[13] Effective 1 October 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.
^The Fourteenth Naval District was an administrative organization responsible for communications and shore activities; its commander reported directly to the Navy Department rather than the commander of the Pacific Fleet.
^Commander, Naval Surface Forces, Pacific (COMNAVSURFPAC) is a post within the United States Pacific Fleet. As Naval Surface Forces, Pacific, it is a military formation, but the organization is often known as COMNAVSURFPAC. Its headquarters are on the West Coast of the United States.
