United States Fifth Fleet

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).

Established during World War II in 1944, the Fifth Fleet conducted extensive operations that led to the defeat of Japanese forces in the Central Pacific, including battles for the Mariana Islands campaign, Iwo Jima, and Okinawa. In 1947, two years after the Allied victory, it was stood down. After remaining inactive for 48 years, the Fifth Fleet was reactivated in 1995. It contributed significant forces in the Global War on Terrorism and continues to project US naval power in the Middle East.

World War II
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.

Halsey then relieved Spruance of command and the British ships, like the rest of the Fifth Fleet, were resubordinated to the Third Fleet.

The Atomic bombings of Hiroshima and Nagasaki made this any further operations unnecessary, and the Fifth Fleet did not return to combat again during the war.

The commanders of 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.

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. However, with the War on Terrorism, the naval strategy of the U.S. has changed. The regular deployments of the Cold War are now a thing of the past. Consequently, the policy of always maintaining a certain number of ships in various parts of the world is also over. 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.

Fifth Fleet forces peaked in early 2003, when five USN aircraft carriers (CV and CVNs), six USN amphibious assault ships (LHAs and LHDs) and their embarked USMC 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 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 USS John C. Stennis (CVN-74) 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 6 January 2012, armed Iranian speedboats reportedly harassed two U.S. naval vessels, the amphibious transport dock USS New Orleans (LPD-18) and the Coast Guard cutter USCGC Adak (WPB-1333), as they transited the Strait of Hormuz into the Persian Gulf.

On 9 January 2012, Carrier Strike Group One, led by the carrier USS Carl Vinson (CVN-70), joined Carrier Strike Group Three in the North Arabian Sea, with Carrier Strike Group Nine, led by the carrier USS Abraham Lincoln (CVN-72), 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 USS Eisenhower (CVN-69). Dwight D. Eisenhower, Carrier Air Wing Seven, and the guided-missile cruiser USS Hue City (CG-66) returned to base on 19 December 2012, and the guided missile destroyers USS Jason Dunham (DDG-109), USS Farragut (DDG-99), and USS Winston S. Churchill (DDG-81) 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 HMS Ocean (L12), along with helicopters from 845 Naval Air Squadron, No. 662 Squadron AAC and No. 27 Squadron RAF, HMS Bulwark (L15), and element of 3 Commando Brigade HQ Royal Marines, RFA Mounts Bay 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.

Coalition Forces Maritime Component Command
Together with Naval Forces Central Command, Fifth Fleet oversees four naval task forces monitoring maritime activity:
 * Combined Task Force 150 that patrols from Hormuz, halfway across the Arabia Sea, South as far as the Seychelles, through the Gulf of Aden, up through the strait between Djibouti and Yemen known as the Bab Al Mandeb and into the Red Sea and, finally, around the Horn of Africa;
