United States Fifth Fleet

The Fifth Fleet was initially established during World War II on 26 April 1944 from the Central Pacific Force under the command of Admiral Raymond Spruance. Central Pacific Force was itself part of Pacific Ocean Areas. The ships of the Fifth Fleet also formed the basis of the Third Fleet, which was the designation of the "Big Blue Fleet" when under the command of Admiral William F. Halsey, Jr. Spruance and Halsey would alternate command of the fleet for major operations, allowing the other admiral and his staff time to prepare for the subsequent one. A secondary benefit was confusing the Japanese into thinking that they were actually two separate fleets as the fleet designation flipped back and forth. Under Admiral Spruance, the Fifth Fleet was, by June 1944, the largest combat fleet in the world, with 535 warships. While operating under Spruance's command as the Fifth Fleet, the fleet took part in the Mariana Islands campaign of June–August 1944, the Iwo Jima campaign of February–March 1945, and the Okinawa campaign of April–June 1945. During the course of these operations, it conducted Operation Hailstone (a major raid against the Japanese naval base at Truk) in February 1944, defeated the Imperial Japanese Navy in the Battle of the Philippine Sea in June 1944, and blunted the Japanese Operation Ten-Go – sinking the Japanese battleship Yamato in the process – in April 1945. The British Pacific Fleet operated as part of the Fifth Fleet from March to May 1945 under the designation Task Force 57. Halsey then relieved Spruance of command and the British ships, like the rest of the Fifth Fleet, were resubordinated to the Third Fleet. The Fifth 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. The size of the operation resulted in plans for the Fifth Fleet to function as a separate command, operating simultaneously with the Third Fleet for the first time. The atomic bombings of Hiroshima and Nagasaki and subsequent cessation of hostilities in August 1945 made this operation unnecessary, and the Fifth Fleet did not return to combat again during the war. The commanders of the Fifth Fleet during this era were Admirals Spruance (26 April 1944 – 8 November 1945), John Henry Towers (8 November 1945 – 18 January 1946), Frederick C. Sherman (18 January 1946 – 3 September 1946), and Alfred E. Montgomery (5 September 1946 – 1 January 1947). The Fifth Fleet was deactivated in January 1947. The position of Commander, Fifth Fleet, became Commander, First Task Fleet. Montgomery became Commander, First Task Fleet, upon the deactivation of the Fifth Fleet. ==In the Middle East after 1995==

Prior to the first Gulf War in 1990–1991, U.S. naval operations in the Persian Gulf region were directed by the Commander, Middle Eastern Force (COMMIDEASTFOR). Since this organization was considered insufficient to manage large-scale combat operations during the Gulf War, the Seventh Fleet — primarily responsible for the Western Pacific and Indian Ocean and normally based in Japan – was given the temporary task of managing the force during the period. However, no numbered fleet existed permanently within the USCENTCOM area of responsibility. In 1995, John Scott Redd proposed and founded the only new U.S. Navy Fleet in half a century, serving as the first Commander, Fifth Fleet (COMFIFTHFLT) since World War II. After a 48-year hiatus, the Fifth Fleet was reactivated, replacing COMMIDEASTFOR, and it now directs operations in the Persian Gulf, Red Sea, and Arabian Sea. Its headquarters are at NSA Bahrain located in Manama, Bahrain. , Royal Navy, and Royal Australian Navy destroyers and frigates on joint operations in the Persian Gulf. For the early years of its existence, its forces normally consisted of an Aircraft Carrier Battle Group (CVBG), an Amphibious Ready Group (ARG), surface combatants, submarines, maritime patrol and reconnaissance aircraft, and logistics ships. After the September 11 terrorist attack and the beginning of Operation Enduring Freedom, the naval strategy of the U.S. changed. Consequently, the policy of always maintaining a certain number of ships in various parts of the world also changed. However, its usual configuration now includes a Carrier Strike Group (CSG), Amphibious Ready Group or Expeditionary Strike Group (ESG), and other ships and aircraft with almost 15,000 people serving afloat and 1,000 support personnel ashore. Carrier Strike Group Three formed the core of the naval power during the initial phase of Operation Enduring Freedom in 2001. Commander, Carrier Group Three, Rear Admiral Thomas E. Zelibor, arrived in the Arabian Sea on 12 September 2001 and was subsequently designated Commander Task Force 50 (CTF 50), commanding multiple carrier strike groups and coalition forces. The Task Force conducted strikes against Al-Qaeda and Taliban forces in Afghanistan. Task Force 50 comprised over 59 ships from six nations including six aircraft carriers, stretching over 800 nautical miles. Naval operations in the Middle East were the subject of DOD Exercise Millennium Challenge 2002, during which unanticipated maneuvers by opposing forces director Lieutenant General Paul Van Riper USMC (retd.) led to heavy losses to the 'imaginary' exercise U.S. fleet. In August 2002, Marines from the 22nd Marine Expeditionary Unit (Special Operations Capable (MEU) (SOC)) carried out a long-range deployment exercise from the amphibious assault ship into Djibouti. During the deployment the MEU also participated in Operation Sea Eagle in the Gulf of Aden and Operation Infinite Anvil in the Horn of Africa. Fifth Fleet forces peaked in early 2003, when five USN aircraft carriers (CV and CVNs), six amphibious assault ships (LHAs and LHDs) and their embarked Marine Corps air ground combat elements, their escorting and supply vessels, and over 30 Royal Navy vessels were under its command. In the Persian Gulf, United States Coast Guard surface ships attached to the Fifth Fleet were under Commander, Destroyer Squadron 50 (CDS-50) commanded by Captain John W. Peterson of the Navy. Coast Guard cutters Boutwell, Walnut, and the four patrol boats were part of this group. The shore detachments, MCSD and Patrol Forces Southwest Asia also operated under the command of CDS-50. For actual operations, the Coast Guard forces were part of two different task forces. The surface units were part of Task Force 55 (CTF-55). Command of CTF-55 actually shifted during OIF. Initially, Rear Admiral Barry M. Costello, Commander of the Constellation Battle Group, commanded CTF-55. The surface forces were designated Task Group 55.1 (TG-55.1) with Commander Destroyer Squadron 50 (CDS-50) as the task group commander. In mid-April, the Constellation Battle Group left the NAG and the Destroyer Squadron 50 staff commanded TF-55 for the remainder of OIF major combat operations. In the aftermath of the fall of Baghdad in April 2003, the very large force of ships was quickly drawn down. On 6 May 2005, a party of Marines reportedly landed in Somaliland, the autonomous and self-declared state in northern Somalia. The landings were purportedly conducted to carry out searches, as well as to question locals regarding the whereabouts of terrorist suspects. Three ships, including a helicopter carrier, were reported in a nearby anchorage, likely a MEU/ARG. United States military officials denied the allegations and said operations were not being conducted in Somaliland. On 3 January 2012, following the end of the ten-day Velayat 90 naval maneuvers by the Iranian Navy in the Strait of Hormuz, the Iranian Army chief of staff, General Ataollah Salehi, was quoted by the state news agency IRNA as warning the United States to not deploy back to the Persian Gulf. On 4 January 2011, Fars News Agency reported that a bill was being prepared for the Iranian Parliament to bar foreign naval vessels from entering the Persian Gulf unless they receive permission from the Iranian navy, with Iranian lawmaker Nader Qazipour noting: "If the military vessels and warships of any country want to pass via the Strait of Hormuz without coordination and permission of Iran's navy forces, they should be stopped by the Iranian armed forces." Also, Iranian Defense Minister Ahmad Vahidi reiterated that "transnational forces" have no place in the Persian Gulf region. On 9 January 2012, Carrier Strike Group One, led by the carrier , joined Carrier Strike Group Three in the North Arabian Sea, with Carrier Strike Group Nine, led by the carrier , en route to the Arabian Sea amid rising tension between the United States and the Islamic Republic of Iran over U.S. naval access to the Strait of Hormuz. On 19 January 2012, Carrier Strike Group Nine entered the Fifth Fleet's area of responsibility (AOR) and relieved Carrier Strike Group Three. That same day during an interview on the Charlie Rose program, Mohammad Khazaee, Iran's ambassador to the United Nations, stated that Iran would consider closing the Strait of Hormuz if Iran's security was endangered. For December 2012 and January 2013, Carrier Strike Group Three was the only carrier strike group operating with the U.S. Fifth Fleet until relieved by the Carrier Strike Group Ten. This is because of the temporary two-month rotation of the Carrier Strike Group Eight back to the United States in order to resurface the flight deck of that group's flagship, the carrier . Dwight D. Eisenhower, Carrier Air Wing Seven, and the guided-missile cruiser returned to base on 19 December 2012, and the guided missile destroyers , , and were scheduled to return to base in March 2013. In September 2016, Commander Amphibious Task Group, Commodore Andrew Burns, set off from the UK with , along with helicopters from 845 Naval Air Squadron, No. 662 Squadron AAC and No. 27 Squadron RAF, , and element of 3 Commando Brigade HQ Royal Marines, and MV Eddystone Point under his flag. This deployment was known as the Joint Expeditionary Force (Maritime) 2016. The Amphibious Task Group was planned to sail to the Red Sea and Persian Gulf, where Burns was to assume command of the United States Fifth Fleet Task Force 50 until March 2017. On 1 December 2018, Commander, Fifth Fleet, Vice Admiral Scott A. Stearney was found dead in his residence in Bahrain. No foul play was suspected. Deputy commander Rear Admiral Paul J. Schlise assumed command in his place. Vice Admiral Jim Malloy flew to Bahrain to provide support. Malloy was formally nominated to succeed Stearney on 4 December and quickly confirmed by voice vote of the full United States Senate on 6 December. Vice Adm. Malloy assumed command on 7 December. On 28 February 2026, as part of a broader retaliatory wave following joint U.S.–Israeli strikes on Iran, Iranian missiles and drones struck the Naval Support Activity Bahrain, the headquarters of the U.S. Fifth Fleet in Manama. Satellite imagery later confirmed that two AN/GSC-52B satellite communications (SATCOM) terminals were destroyed, along with damage to several warehouses and at least one base service facility. == Composition ==
