The United States Third Fleet is one of the numbered fleets in the United States Navy. Third Fleet's area of responsibility includes approximately fifty million square miles of the eastern and northern Pacific Ocean areas including the Bering Sea, Alaska, the Aleutian Islands, and a sector of the Arctic. Major oil and trade sea lines of communication within this area are critically important to the economic health of the United States and friendly nations throughout the Pacific Rim region.[1]
First established in 1943, the Third Fleet conducted extensive operations against Japanese forces in the Central Pacific during World War II. Deactivated in 1945, the fleet remained inactive until 1973, when it was reactivated and assumed its current responsibilities.
Mission
The Third Fleet plans and executes naval operations in the Pacific Ocean. The fleet provides maritime homeland defense, regional security, and humanitarian operations support through integrated naval and coastguard forces acting as a single Sea Service. It strengthens relations between the U.S. and its allies and partners through joint, inter-agency and multinational exercises and operations like Rim of the Pacific, Pacific Partnership, and Fleet Weeks. The Third Fleet ensures realistic, relevant training to its personnel so they have the necessary skills to promote peace and prevail in conflict.[2]
The Third Fleet was originally formed during World War II on 15 March 1943 under the command of Admiral William F. Halsey. Its on-shore headquarters at Pearl Harbor, Hawaii was established on 15 June 1944. The ships of the Third Fleet also formed the basis of the Fifth Fleet, formed on 26 April 1944, which was the designation of the "Big Blue Fleet" when under the command of Admiral Raymond A. Spruance.[note 1] Spruance and Halsey alternated command of the fleet for major operations, allowing the other admiral and his staff time to plan for subsequent operations. A secondary benefit was confusing the Japanese into thinking that there were actually two separate fleets as the fleet designation flipped back and forth.[4]
The British Pacific Fleet was operating as Task Force 57 of the Fifth Fleet when Halsey relieved Spruance of command in May 1945. Like the rest of the Fifth Fleet's ships, the British ships were resubordinated from Spruance's Fifth Fleet to Halsey's Third Fleet. The British Pacific Fleet then constituted Task Force 37 under the Third Fleet's operational command through the end of World War II on 15 August 1945.
The Third Fleet's next major combat operation would have been Operation Olympic, the invasion of Kyushu in the Japanese Home Islands, scheduled to begin on 1 November 1945, during which it would have operated simultaneously with the Fifth Fleet for the first time.[contradictory] The end of the war made this operation unnecessary.
Embarked aboard Missouri, Admiral Halsey led the Third Fleet into Tokyo Bay on 29 August 1945. On 2 September 1945, the documents of surrender of the Japanese Empire ending the war were signed on Missouri's deck. The Third Fleet remained in Japanese waters until late September 1945, when its ships were directed to proceed to the United States West Coast. On 7 October 1945, the Third Fleet was designated a reserve fleet and decommissioned from active status.

On 1 February 1973, following a reorganization of the Pacific Fleet, the Third Fleet was recommissioned as an active fleet and assumed the duties of the former First Fleet and Pacific Anti-Submarine Warfare Force located at Ford Island, Hawaii. Third Fleet's new duties were to train naval forces for overseas deployment and evaluate state-of-the-art technology for fleet use. Additionally, Third Fleet could deploy in the event of a major conflict.
On 26 November 1986, Commander, Third Fleet shifted his flag from his headquarters ashore to resume status as an afloat commander for the first time since World War II, aboard USSCoronado. In August 1991, Third Fleet's commander, his staff and the command ship Coronado shifted homeports to San Diego. In September 2003, Commander, Third Fleet shifted his flag from the command ship Coronado to headquarters ashore at Point Loma, San Diego, California.[5]
In 2015, Nora Tyson was installed as the new commander of the Third Fleet, making her the first woman to lead a numbered fleet in the U.S. Navy.[9][10]
In peacetime, Third Fleet continually trains Navy and U.S. Marine Corps forces for their expeditionary warfare mission. Third Fleet training has been designed to ensure that deploying forces are fully prepared for joint operations. All training is conducted within a joint environment—employing joint doctrine, terminology, procedures, command and control—to ensure that forces are ready to join with the other United States armed forces branches under a joint command structure.
Commander, Third Fleet is also designated as a Joint Task Force (JTF) commander. In that capacity, the commander and their staff may be assigned responsibilities for command of joint U.S. forces deployed in response to a specific event or contingency. As such, the JTF commander reports via a joint chain of command to a unified commander. Commander, U.S. Pacific Command is the unified commander in the Pacific theater.
To allow 7th Fleet to focus more resources on a potential North Korean contingency, the 3rd Fleet is building up its ability to operate forces beyond the International Date Line, in areas of the Western Pacific hitherto commanded by 7th Fleet. The "3rd Fleet Forward" concept was announced by U.S. Pacific Fleet commander Admiral Scott Swift in 2015, but 3rd Fleet commander Vice Adm. Nora Tyson said at the "WEST 2017" conference that the North Korean threat was a main driver behind this effort:[11]
"What we have done in the past really 18 months is we, 3rd Fleet, have worked very closely with 7th Fleet and PACFLT in developing our, 3rd fleet's, capability to command and control forces forward in the Western Pacific, with the assumption that if something were to happen – and as [Vice Admiral Joseph Aucoin, Commander 7th Fleet] said, the number-one probability fight-tonight scenario would be on the Korean Peninsula. "If that were the case, the assumption is that [Aucoin] and his team would be pretty busy up there.. working for General Brooks [ComUSFK/CFC/UNC] and 3rd Fleet would be available to provide that command element to handle whatever else may happen in the Pacific Fleet AOR ...be it a major humanitarian disaster requiring that level of [joint task force] three-star commander, be it some scenario, maritime security issue in the South China Sea. So we have been working very closely with 7th Fleet, [Aucoin] and his team, and PACFLT to ensure that we have the connective tissue where if something were to happen that 3rd Fleet could very quickly respond, complement [Aucoin] and his team and handle whatever scenario may come to pass in the Pacific theater."
In April 2016, Vice Admiral Tyson deployed a three-ship Surface Action Group of warships (Momsen,Spruance, and USSDecatur(DDG-73))[12]) to the Western Pacific. On Oct. 21, one of them, the destroyer USS Decatur conducted a "Freedom of Navigation" passage near the Paracel Islands, separately claimed by the PRC, Vietnam and Taiwan. All three ships remained under Third Fleet command during the entire operation. As Tyson partially acknowledged during her WEST 2017 conference remarks, "the Chinese know that this administrative (and) operational innovation is directed at them," said Toshi Yoshihara, a U.S. Naval War College professor in January 2017.[13]

Notes
↑ The "Big Blue Fleet" was the name given to the main fleet of the U.S. Navy in the Pacific. The term stems from pre-war planning, called the "color plans" because each nation included was given a color code name. In these plans for potential conflicts, the British Royal Navy was "Red," the German Navy was "Black," and so forth. The Imperial Japanese Navy was termed the "Orange Fleet," while the U.S. fleet was the "Blue Fleet". The "Big Blue Fleet" was the massive fleet that the U.S. Navy anticipated it would field to win a war with Japan and which it thought largely would come into being by late 1943 or early 1944.[3]

The Battle of Leyte Gulf was the largest naval battle of World War II and by some criteria the largest naval battle in history, with over 200,000 naval personnel involved.
William Frederick "Bull" Halsey Jr. was an American Navy admiral during World War II. He is one of four officers to have attained the rank of five-star fleet admiral of the United States Navy, the others being William Leahy, Ernest J. King, and Chester W. Nimitz.
Carrier Strike Group 9 is a U.S. Navy carrier strike group. Commander Carrier Strike Group 9 is responsible for unit-level training, integrated training, and material readiness for the ships and aviation squadrons assigned to the group. The group reports to Commander, U.S. Third Fleet, which also supervises its pre-deployment training and certification that includes Composite Unit Training Exercises.
Raymond Ames Spruance was a United States Navy admiral during World War II. He commanded U.S. naval forces during the Battle of the Philippine Sea, one of the most significant naval battles of the Pacific Theatre. He also commanded Task Force 16 at the Battle of Midway, comprising the carriers Enterprise and Hornet. At Midway, dive bombers from Enterprise sank four larger carriers of the Imperial Japanese Navy. Most historians consider Midway the turning point of the Pacific War.
The Battle of the Philippine Sea was a major naval battle of World War II on 19–20 June 1944 that eliminated the Imperial Japanese Navy's ability to conduct large-scale carrier actions. It took place during the United States' amphibious invasion of the Mariana Islands during the Pacific War. The battle was the last of five major "carrier-versus-carrier" engagements between American and Japanese naval forces, and pitted elements of the United States Navy's Fifth Fleet against ships and aircraft of the Imperial Japanese Navy's Mobile Fleet and nearby island garrisons. This was the largest carrier-to-carrier battle in history, involving 24 aircraft carriers, deploying roughly 1,350 carrier-based aircraft.
The Fast Carrier Task Force was a group of ships in World War II. It was the main striking force of the United States Navy in the Pacific War from January 1944 through the end of the war in September 1945. The task force was made up of several separate task groups, each typically built around three to four aircraft carriers and their supporting vessels. The support vessels were screening destroyers, cruisers, and the newly built fast battleships.
The Seventh Fleet is a numbered fleet of the United States Navy. It is headquartered at U.S. Fleet Activities Yokosuka, in Yokosuka, Kanagawa Prefecture, Japan. It is part of the United States Pacific Fleet. At present, it is the largest of the forward-deployed U.S. fleets, with 50 to 70 ships, 150 aircraft and 27,000 Sailors and Marines. Its principal responsibilities are to provide joint command in natural disaster or military operations and operational command of all U.S. naval forces in the region.
The Fifth Fleet is a numbered fleet of the United States Navy. Its area of responsibility encompasses approximately 2.5 million square miles, and includes the Persian Gulf, Red Sea, Arabian Sea, and parts of the Indian Ocean. It shares a commander and headquarters with U.S. Naval Forces Central Command (NAVCENT) in Bahrain. Fifth Fleet/NAVCENT is a component command of, and reports to, U.S. Central Command (CENTCOM).
Marc Andrew "Pete" Mitscher was a pioneer in naval aviation who became an admiral in the United States Navy, and served as commander of the Fast Carrier Task Force in the Pacific during World War II.
Thomas Cassin Kinkaid was an admiral in the United States Navy, known for his service during World War II. He built a reputation as a "fighting admiral" in the aircraft carrier battles of 1942 and commanded the Allied forces in the Aleutian Islands Campaign. He was Commander Allied Naval Forces and the Seventh Fleet under General of the Army Douglas MacArthur in the Southwest Pacific Area, where he conducted numerous amphibious operations, and commanded an Allied fleet during the Battle of Leyte Gulf, the largest naval battle of World War II and the last naval battle between battleships in history.
USS Hull (DD-350) was a Farragut-class destroyer in the United States Navy during World War II. She was named for Isaac Hull.
Miles Rutherford Browning was an officer in the United States Navy in the Atlantic during World War I and in the Pacific during World War II. An early test pilot in the development of carrier-based Navy aircraft and a pioneer in the development of aircraft carrier combat operations concepts, he is noted for his aggressive aerial warfare tactics as a Navy captain on the Admiral's staff aboard USS Enterprise and at Nouméa during World War II. His citation for the Distinguished Service Medal states: "His judicious planning and brilliant execution was largely responsible for the rout of the enemy Japanese fleet in the Battle of Midway." Naval historian Craig Symonds disagrees, however, writing that "the citation claim that Browning was 'largely responsible' for the American victory at Midway, an assertion that some historians have taken seriously. .. is manifestly untrue."
A carrier strike group (CSG) is a type of carrier battle group of the United States Navy. It is an operational formation composed of roughly 7,500 personnel, usually an aircraft carrier, at least one cruiser, a destroyer squadron of at least two destroyers or frigates, and a carrier air wing of 65 to 70 aircraft. A carrier strike group also, on occasion, includes submarines, attached logistics ships and a supply ship. The carrier strike group commander operationally reports to the commander of the numbered fleet, who is operationally responsible for the area of waters in which the carrier strike group is operating.
John Sidney "Slew" McCain Sr. was a United States Navy admiral and the patriarch of the McCain military family. McCain held several commands during the Pacific War of World War II and was a pioneer of aircraft carrier operations. He and his son, John S. McCain Jr., were the first father-and-son pair to achieve four-star admiral rank in the U.S. Navy.
Carrier Strike Group One is a U.S. Navy carrier strike group. USS Carl Vinson (CVN-70) is the strike group's current flagship, and other units currently assigned are the ship's Carrier Air Wing 2 and embarked Destroyer Squadron 1, deployed with Ticonderoga-class guided-missile cruiser USS Lake Champlain, as well as Arleigh Burke-class guided-missile destroyers USS Michael Murphy and USS Wayne E. Meyer.
Carrier Strike Group 15, is a training formation of the United States Navy. It trains and certifies Pacific Fleet Carrier Strike Groups, Amphibious Ready Groups, and independently deploying surface ships. It replaced Commander, Strike Force Training Pacific in a title change. Carrier Strike Group Four is the equivalent command for US Fleet Forces ships.
Carrier Strike Group Seven was a U.S. Navy carrier strike group active from October 2004 until 30 December 2011. The strike group's antecendants included two previous aircraft carrier formations, Carrier Division Seven and Carrier Group Seven. Its heritage thus includes the Second World War, the Vietnam War, and the Cold War, as well as the first and the second Persian Gulf wars, encompassing a total of 34 deployments to the Western Pacific Ocean and Persian Gulf.
Summer Pulse 2004 (SP04) was the codename for a worldwide surge deployment that served as the first full-scale test of the United States Navy's then-new Fleet Response Plan (FRP). During Summer Pulse 2004, a total of seven carrier strike groups were underway at the same time in five different Numbered fleet areas of responsibility. This number of underway carrier strike groups had not been matched since the six carrier battle groups deployed during Operation Desert Storm. In addition to the carriers, the Navy also deployed 17 submarines and one submarine tender.
Carrier Strike Group 5, also known as CSG 5 or CARSTRKGRU 5, is the U.S. Navy carrier strike group assigned to the United States Pacific Fleet and permanently forward deployed to the U.S. 7th Fleet. The Strike Group Flagship is the Nimitz-class aircraft carrier USS George Washington (CVN-73) which also embarks Strike Warfare Commander, Carrier Air Wing Five and its nine squadrons. As of June 2015, CSG 5 includes two Ticonderoga-class cruisers and Destroyer Squadron Fifteen, which serves as the Sea Combat Commander and is responsible for nine assigned Arleigh Burke-class destroyers.
