104-478: It replaces the MK 7 hydraulic arresting gear which is in use on the ten Nimitz-class aircraft carriers . The AAG is designed for a broader range of aircraft, including UAVs, while reducing manpower and maintenance. Rotary engines which use simple energy-absorbing water turbines (or twisters) coupled to a large induction motor provide finer control of the arresting forces. On March 31, 2016, GA-EMS, in collaboration with

208-527: A CATOBAR arrangement to operate aircraft, with steam catapults and arrestor wires for launch and recovery. As well as speeding up flight deck operations, this allows for a much wider variety of aircraft than with the STOVL arrangement used on smaller carriers. An embarked carrier air wing comprising around 64 aircraft is normally deployed on board. The air wings' strike fighters are primarily F/A-18E and F/A-18F Super Hornets . In addition to their aircraft,

This can be in combat operations, such as the NATO bombing of Yugoslavia in 1999, or training deployments, such as Exercise RIMPAC . In addition, carriers have participated in international Maritime security operations , combating piracy in

1768-407: A so-called ' Thursday War '. She then moved towards Portsmouth , United Kingdom, on 27 May, anchoring adjacent to Stokes Bay through 31 May, because she was too large to enter the harbor, and the naval base did not have sufficient nuclear berths for the carrier to moor alongside. The carrier arrived at Naples, Italy on 10 June 2011. The carrier returned to Norfolk on 10 December 2011, following

1872-629: A spokesperson for Naval Air Force Atlantic confirmed that a "small number" of sailors assigned to George H.W. Bush had tested positive for COVID-19 during the summer. The spokesperson declined to provide an exact number of sailors or a more precise date regarding when the virus was detected, citing US Defense Department policy, but added that the carrier was not deployed at the time, and that those infected "remain[ed] in isolation at their private residences in Virginia and receive[d] daily medical supportive care". In August 2020, George H.W. Bush left dry dock at Norfolk Naval Shipyard, after 18 months of

1976-582: A study to determine if the Nimitz -class carrier lives could be extended to as long as 55 years. USS George H.W. Bush USS George H.W. Bush (CVN-77) is the tenth and final Nimitz -class supercarrier of the United States Navy . She is named for the 41st President of the United States and former Director of Central Intelligence George H. W. Bush , who was a naval aviator during World War II . The vessel's callsign

2080-786: A target. As a result of its target value and vulnerability, aircraft carriers are always escorted by at least one submarine for protection. The other vessels in the Strike Group provide additional capabilities, such as long-range Tomahawk missiles or the Aegis Combat System , and protect the carrier from attack. A typical Strike Group may include, in addition to an aircraft carrier: up to six surface combatants , including guided-missile cruisers and guided-missile destroyers , used primarily for anti-aircraft warfare and anti-submarine warfare, and frigates / guided-missile frigates , prior to their retirement from USN service. When

2288-811: Is Avenger , after the TBF Avenger aircraft flown by then-Lieutenant George H. W. Bush in World War II . Construction began in 2003 at Northrop Grumman , in Newport News, Virginia and was completed in 2009 at a cost of $ 6.2 billion. Her home port is Naval Station Norfolk , Virginia. George H. W. Bush became one of the U.S. Navy's youngest pilots when he received his Naval Aviator wings and naval commission on 9 June 1943, three days before turning 19. He flew torpedo bombers off USS  San Jacinto on active duty from August 1943 to September 1945 during World War II. On 2 September 1944, during

2392-426: Is a similar procedure, although it is less substantial and does not involve refueling the nuclear power plants. Because of their status as the largest warships in the U.S. Navy, the deployment of an aircraft carrier can fulfill a symbolic role, not just as a deterrent to an enemy but often as a diplomatic tool in strengthening relations with allies and potential allies. The latter of these functions can occur either as

2496-460: Is angled at nine degrees, which allows for aircraft to be launched and recovered simultaneously. This angle of the flight deck was reduced slightly compared to previous carriers, as the current design improves the airflow around the carrier. Four steam catapults are used to launch fixed-wing aircraft, and four arrestor wires are used for recovery. The two newest carriers, Ronald Reagan and George H.W. Bush , have only three arrestor wires each, as

2600-524: Is estimated to cost from $ 750 to $ 900 million. This compares with an estimated $ 53 million for a conventionally powered carrier. Most of the difference in cost is attributed to the deactivation of the nuclear power plants and the safe removal of radioactive material and other contaminated equipment. A new class of carriers, the Gerald R. Ford class, is being constructed to replace previous vessels after decommissioning. Ten of these are expected, and

2704-742: Is the second carrier to have a modernized island, which includes a new radar tower (enclosed to reduce radar signature), navigation system upgrades, communication systems enhancements, and armored windows. The island is smaller and has been repositioned further aft to improve flight deck access and reduce signature and electronic self-interference. New air operations design features include an updated aviation fuel storage and distribution system, semi-automated refueling and servicing with new deck locations to provide faster, more efficient aircraft pit stops, requiring fewer people, modernized aircraft launch, and recovery equipment, and redesigned jet blast deflectors . Environmental upgrades have also been designed into

2808-520: The Atlantic Ocean , including the first time that an unmanned drone has been catapulted off an aircraft carrier on the morning of 14 May 2013 ( pictured ). On 17 May 2013, another first was achieved when the X-47B performed touch-and-go landings and take-offs on the flight deck of Bush while underway in the Atlantic Ocean. Also during this two-week underway period, the aircraft carrier tested

2912-759: The Franco -American exercise Chesapeake Mission, with twelve Dassault Aviation Rafale M and a Grumman E-2C Hawkeye from the French Navy embarked on board. In February 2019, George H.W. Bush arrived at Norfolk Naval Shipyard for a planned 28-month docking planned incremental availability (DPIA). This was the ship's first DPIA. The United States Navy announced on 24 September that there had been three suicides aboard George H.W. Bush in one week. Two previous ship suicides had taken place in November 2017 and July 2019. On 30 July 2020 , Navy Times reported that

In 1987, Carl Vinson participated in the first U.S. carrier deployment in the Bering Sea , and Nimitz provided security during the 1988 Olympic Games in Seoul . The two most significant deployments the  Nimitz class

3120-518: The Kitty Hawk class. Among other design improvements, the two reactors on Nimitz -class carriers take up less space than the eight reactors used on Enterprise . Along with a more generally improved design, Nimitz -class carriers can carry 90% more aviation fuel and 50% more ordnance when compared to the Forrestal class. The U.S. Navy has stated that the carriers could withstand three times

3224-402: The Nimitz class is made up only of short-range defensive weapons, used as a last line of defense against enemy missiles and aircraft. As with all surface ships, an aircraft carrier is particularly vulnerable to attack from below, specifically from submarines. An aircraft carrier is a very expensive, hard to replace, and strategically valuable asset, and therefore it logically has immense value as

The flight deck

3744-617: The Vietnam War , and certain aspects of the design were influenced by operations there. To a certain extent, the carrier operations in Vietnam demonstrated the need for increased capabilities of aircraft carriers over their survivability; they were used to send sorties into the war and were, therefore, less subject to attack. As a result of this experience, Nimitz -class carriers were designed with larger stores of aviation fuel and larger magazines compared to previous carriers, although this

3848-825: The West Coast of the United States . All active ships have been involved in Iraq and Afghanistan since that time. This included the invasion in 2003, as well as providing subsequent support for Operation Iraqi Freedom since then. The carriers have also provided aid after natural disasters. In 2005, Abraham Lincoln supported Operation Unified Assistance in Indonesia after the December 2004 tsunami , and Harry S. Truman provided aid after Hurricane Katrina later in 2005. The Ronald Reagan Carrier Strike Group performed humanitarian assistance and disaster relief operations in

3952-975: The 1990s and more recently, Nimitz -class carriers have been deployed as part of humanitarian missions. While deployed in the Gulf War, Abraham Lincoln was diverted to the Pacific Ocean to participate alongside 22 other ships in Operation Fiery Vigil , evacuating civilians following the eruption of Mount Pinatubo on Luzon Island in the Philippines. In October 1993, Abraham Lincoln deployed to Somalia to assist UN humanitarian operations there, spending four weeks flying patrols around Mogadishu while supporting U.S. troops during Operation Restore Hope . The same ship also participated in Operation Vigilant Sentinel in

4056-409: The 2008 RIMPAC exercises and delayed the final withdrawal from service of USS  Kitty Hawk . The fire was caused by unauthorized smoking near improperly stored flammable refrigerant compressor oil. Nimitz -class carriers were initially designed to have a 50-year service life. At the end of their service life, ships will be decommissioned . This process will first take place on Nimitz and

4160-789: The Mk 49 Guided Missile Launching Systems for RIM-116 Rolling Airframe Missiles , two of which have also been installed on USS  Nimitz and USS  George Washington . These will be installed on the other ships as they return for Refueling Complex Overhaul (RCOH). Since USS Theodore Roosevelt , the carriers have been constructed with 2.5 in (64 mm) Kevlar armor over vital spaces, and earlier ships have been retrofitted with it: Nimitz in 1983–1984, Dwight D. Eisenhower from 1985 to 1987 and Carl Vinson in 1989. The ships' other countermeasures are four Sippican SRBOC (super rapid bloom off-board chaff ) six-barrel Mk 36 decoy launchers, which deploy infrared flares and chaff to disrupt

Also making up part of the group is one or two attack submarines for seeking out and destroying hostile surface ships and submarines and an ammunition, oiler, and supply ship from Military Sealift Command to provide logistical support. The numbers and types of vessels that make up each strike group can vary from group to group, depending on deployments, mission, and availability. While

4472-657: The Persian Gulf and off the coast of Somalia. On 26 May 1981, an EA-6B Prowler crashed on the flight deck of Nimitz , killing 14 crewmen and injuring 45 others. Forensic testing of the personnel involved showed that several tested positive for marijuana. While this was not found to have directly caused the crash, the investigation's findings prompted the introduction of mandatory drug testing of all service personnel. Pilots have been able to eject safely in several cases of ditched aircraft. However, fatal aircraft crashes have occurred; in 1994, Lieutenant Kara Hultgreen ,

4576-619: The Persian Gulf intending to support Operation Southern Watch in July 2001. This changed in response to the attacks, and the ship changed course to travel towards the North Arabian Sea, where she launched the first airstrikes in support of the operation on 7 October 2001. Following the attacks, John C. Stennis and George Washington participated in Operation Noble Eagle , carrying out homeland security operations off

In order to refuel their nuclear power plants,

4784-568: The U.S. Navy, conducted the arrestment of an F/A-18E Super Hornet at the Runway Arrested Landing Site (RALS) located at Joint Base McGuire–Dix–Lakehurst , New Jersey. Previously, AAG tests had only involved inert loads simulating the weight of aircraft at a jet engine testing track installed at the base. The first inert load arrestment was March 27, 2011 and the first fly-in arrestment was October 13, 2016. That site has executed more than 1,200 inert load arrestments. Testing

4888-429: The U.S. government. As a result, the presence of a U.S. aircraft carrier in a foreign port has occasionally provoked protest from local people, for example, when Nimitz visited Chennai , India, in 2007. At that time, the Strike Group commander Rear Admiral John Terence Blake stated, "The U.S. policy [...] is that we do not routinely deploy nuclear weapons on board Nimitz ." In May 2013, George H.W. Bush conducted

4992-696: The UK to take part in Exercise Saxon Warrior , a joint exercise involving Carrier Strike Group 2 plus elements of the Royal Navy , German Navy , Royal Norwegian Navy and Swedish Navy .

The reactors produce steam to drive steam turbines which drive four propeller shafts and can produce a maximum speed of over 30 knots (56 km/h; 35 mph) and a maximum power of around 260,000 shaft horsepower (190 MW). As

7176-446: The four bronze propellers, each with a diameter of 25 feet (7.6 m) and a weight of 66,000 pounds (30 t). Behind these are the two rudders, which are 29 feet (8.8 m) high and 22 feet (6.7 m) long, and each weighs 110,000 pounds (50 metric tons). The Nimitz -class ships constructed since USS  Ronald Reagan also have bulbous bows to improve speed and fuel efficiency by reducing wave-making resistance . As

7280-401: The fourth was used infrequently on earlier ships and was therefore deemed unnecessary. This CATOBAR arrangement allows for faster launching and recovery as well as a much wider range of aircraft that can be used on board compared with smaller aircraft carriers, most of which use a simpler STOVL arrangement without catapults or arrestor wires. The ship's aircraft operations are controlled by

7384-472: The island during the ceremony. George H.W. Bush was christened on 7 October 2006. Former president George H. W. Bush attended the ceremony and became the first president in history to participate in the christening of his namesake ship. President George W. Bush also attended and honored his father during the ceremony as a special guest speaker. Other officials participating in the ceremony included Secretary of Defense Donald Rumsfeld , Secretary of

7488-520: The landing. The Navy stated that the aircraft's detection of a problem demonstrated its reliability and ability to operate autonomously. On 15 July 2013, in a fourth attempt, an X-47B drone failed to make a successful flight deck landing on board the vessel due to "technical issues." In late February 2014, George H.W. Bush transited the Strait of Gibraltar on the way to a stop in Piraeus , Greece, for

7592-593: The large time periods between the ships' constructions, the armament and designs of the newer ships are more modern than those of the older ships. In RCOH, the older ships are refitted to the standards of the newer ships, which can include upgrades to the flight deck, aircraft catapults, combat systems, and radar systems; precise details can vary significantly between the ships. The improvements normally take around four years to complete. The RCOH for USS Theodore Roosevelt took four years to complete (2009–2013) and cost about $ 2.6 billion. Planned Incremental Availability

7696-404: The mast " which dates from antiquity and consists of placing coins or other items of significance under the step or bottom of a ship's mast during construction. Since at least the construction of USS  Constitution in the 1790s, this tradition has been passed on as a symbol of good luck for U.S. Navy ships. George H. W. Bush participated in the event, placing his naval aviator wings underneath

7800-522: The more modern vessels. This problem has been previously rectified by using damage control voids for ballast, but a solution using solid ballast that does not affect the ship's survivability has been proposed. All ten Nimitz -class carriers were constructed between 1968 and 2006 at Newport News Shipbuilding in Newport News, Virginia. The first three units of the class were erected in Dry Dock 11,

7904-560: The motto "Freedom at Work" is adapted from Bush's inaugural speech, during which he said, "We know what works: Freedom works. We know what’s right: Freedom is right." George H.W. Bush measures 1,092 feet (333 m) and displaces over 100,000 tons, making her one of the world's largest warships (though she is slightly shorter than USS  Enterprise ). Her top speed exceeds 30 knots; powered with two nuclear reactors, she can operate for more than 20 years without refueling. Several features differentiate CVN-77 from other ships in

8008-475: The order to "man our ship and bring her to life!" A GM -built Grumman TBM Avenger like the one then-Lieutenant junior grade George Bush flew in World War II performed a fly-over. Northrop Grumman Corporation Builder's sea trials were completed on 16 February 2009, providing an opportunity to test systems, components and compartments at sea for the first time. The trials included high-speed runs and

8112-443: The other seven ships were constructed in the largest dry dock in the western hemisphere, Dry Dock 12, now 2,172 feet (662 m) long after a recent expansion. Beginning with USS  Theodore Roosevelt , the aircraft carriers were manufactured with modular construction. This means that whole sections could be welded together with plumbing and electrical equipment already fitted, improving efficiency. The modules were lifted into

8216-400: The planned two-year overhaul. It was the vessel's most extensive maintenance period and marked the first time out of water since she was built. The overhaul was the most complex undertaken at the shipyard to date, according to the Navy. On 10 August 2022, George H.W. Bush , with Carrier Air Wing 7 (CVW-7) embarked, began a deployment as part of Carrier Strike Group 10 (CSG-10). This marks

8320-429: The seal's horizon represent Bush's concept of a " thousand points of light ", wherein he urged Americans to find meaning and reward by serving a purpose higher than themselves. The graphic depiction of the aircraft carrier reflects the carrier, as both a symbol and instrument of American strength as a force for freedom. Above the carrier are the overhead profiles of a TBM Avenger torpedo bomber (representing Bush's days as

8424-508: The sensors of incoming missiles; an SSTDS torpedo defense system; and an AN/SLQ-25 Nixie torpedo countermeasures system. The carriers also use AN/SLQ-32(V) jamming systems to detect and disrupt hostile radar signals in addition to the electronic warfare capabilities of some of the aircraft on board. The presence of nuclear weapons on board U.S. aircraft carriers since the end of the Cold War has neither been confirmed nor denied by

8528-504: The ship's post shakedown availability (PSA). A PSA is a typical availability in the early life of a carrier that allows the Navy and builder to resolve any items that came up during trials and delivery and make any last-minute changes and upgrades. Work includes the installation of a Rigid Hull Inflatable Boat (RHIB) handling system and a new fresh water purification system. Other changes include compartment reconfigurations, combat system and radar equipment upgrades, and minor repairs. The work

8632-581: The ship, including a vacuum collection/marine sanitation device (VC/MSD), a new marine sewage system that uses sea water in lieu of fresh water for lower maintenance costs. Many older ships in the U.S. Navy utilize a gravity-driven collection holding and transfer (CHT) system to handle sewage waste. Newer U.S. Navy ships, including now CVN-77, collect sewage waste by vacuum, allowing for greater flexibility in piping installation, smaller pipe sizes overall and reducing water consumption. The collection tanks of George H.W. Bush were modified to accommodate both

8736-531: The ship. Automated material movement devices, semi-autonomous, gravity compensated weapons handling devices, damage control automation systems and components have also been installed. Medical and dental equipment have been upgraded, integrated display screens in Damage Control Central have been modernized to improve data integration and display, and equipment in general shops has been modernized to improve productivity. The contract to build CVN-77

8840-436: The ships' equipment. The ships were initially classified only as attack carriers but have been constructed with anti-submarine capabilities since Carl Vinson . These improvements include more advanced radar systems and facilities enabling the ships to operate aircraft in a more effective anti-submarine warfare role, including fitting common undersea picture (CUP) technology, which uses sonar to allow for better assessment of

8944-504: The threat from submarines. Theodore Roosevelt and later carriers have slight structural differences from the earlier Nimitz carriers, such as improved protection for ordnance stored in their magazines . Other improvements include upgraded flight deck ballistic protection, first installed on George Washington , and the high-strength low-alloy steel (HSLA-100) used for constructing ships starting with John C. Stennis . More recently, older ships have had their flight decks upgraded with

9048-442: The toilets. During a four-month maintenance period in the dock in 2012, anti-clog measures were installed in the ship's toilet disposal systems. New electronics and communications technology, space rearrangement, operational procedure changes, advanced sensor technologies and maintenance systems have been incorporated to reduce manning costs. A new zonal electrical distribution system will keep problems from affecting other parts of

9152-473: The vessels carry short-range defensive weaponry for anti-aircraft warfare and missile defense. The unit cost was about US$ 8.5 billion in FY 2012 dollars, equal to US$ 11.2 billion in 2023. The Nimitz -class aircraft carriers have a length of 1,092 ft (333 m) overall and 1,040 ft (317 m) at the waterline, with a beam of 252 ft (77 m) overall and 134 ft (41 m) at

9256-791: The waterline; the individual ships have slight variations in their dimensions. They were initially designed with a full-load displacement of 87,000 long tons (88,000 t; 97,000 short tons) and a draft of 37 ft (11 m), but the ships would be delivered several thousand tons heavier, particularly for later members of the class. As the vessels were overhauled and installed more equipment, loaded displacement would climb to exceed 100,000 long tons (100,000 t; 110,000 short tons). For example, USS  Abraham Lincoln currently displaces 104,112 long tons (105,783 t; 116,605 short tons) at full load. The ships' nominal complement comprises: 3,000–3,200; 1,500 (air wing); and 500 (other). The Nimitz -class aircraft carriers were ordered to supplement

9360-507: The weight of actual aircraft. On 11 August 2008, the Pre-Commissioning Unit (PCU) crew moved aboard the ship, the first meals were served in the galley, the U.S. flag was raised on the fantail for the first time, and the first watches were set. George H.W. Bush left Northrop Grumman Ship Building for the first time on 23 December 2008, proceeding a few miles down river to Norfolk Naval Station . George H.W. Bush

9464-403: The western hemisphere. The keel laying ceremony was held on 6 September 2003, with former president George H. W. Bush serving as the keynote speaker. Former First Lady Barbara Bush also attended with their daughter, Dorothy Bush Koch, the ship's sponsor. The former president authenticated the keel by chalking his initials onto a metal plate. His initials were then welded onto the plate, which

9568-692: Was Operation Eagle Claw launched by Nimitz in 1980 after she had deployed to the Indian Ocean in response to the taking of hostages in the U.S. embassy in Tehran . Although initially part of the U.S. Atlantic Fleet , Dwight D. Eisenhower relieved Nimitz in this operation after her service in the Mediterranean Sea . Nimitz conducted a Freedom of Navigation exercise alongside the aircraft carrier USS  Forrestal in August 1981 in

9672-403: Was $ 6.2 billion. The earlier Nimitz -class ships each cost around $ 4.5 billion. To lower costs, some new technologies and design features were also incorporated into USS Ronald Reagan , the previous carrier, including a redesigned island . The United States Navy lists the following ten ships in the Nimitz class: One of the first major operations in which the ships were involved

9776-571: Was an underestimation of the forces involved inside the water twister because it is a three-dimensional flow field. Internal plates that take the force of the water weren't strong enough, and finding a solution proved difficult. In 2016 the Office of the Inspector General, U.S. Department of Defense found that the AAG remained unproven. On 28 July 2017, Lt. Cmdr. Jamie "Coach" Struck of Air Test and Evaluation Squadron 23 (VX-23) performed

9880-543: Was awarded to Northrop Grumman Shipbuilding Newport News on 26 January 2001. A naming ceremony was held on 9 December 2002 at Northrop Grumman Newport News , with former president George H.W. Bush attending. Secretary of the Navy Gordon R. England , presided at the ceremony. Construction took place at the Northrop Grumman Newport News shipyard's Dry Dock 12, the largest in

9984-418: Was commissioned 10 January 2009 at Norfolk Naval Station prior to her official delivery to the Navy, in a ceremony attended by approximately 15,000 people. Veterans of USS  San Jacinto , the ship George H. W. Bush served on during World War II, were also present. President George W. Bush delivered the principal address, George H. W. Bush set the first watch, and ship's sponsor Dorothy "Doro" Bush Koch gave

10088-399: Was delayed four and a half years due primarily to a serious problem with the water twisters, discovered early in 2012. Existing water twister systems are fixed in their capacity to absorb energy. For AAG there is a variable energy dissipation by the water twister. There is an actual moving plate inside the water twister that adjusts how much resistance to the water is generated. Initially there

10192-660: Was in November 2000. The carrier's air wing flew 869 combat sorties in support of Operation Southern Watch, including a strike on Iraqi air defense sites on 16 February 2001, in response to Iraqi surface-to-air missile fire against United Nations coalition forces. After the September 11 attacks , Carl Vinson and Theodore Roosevelt were among the first warships to participate in Operation Enduring Freedom in Afghanistan. Carl Vinson sailed towards

10296-523: Was involved in during the 1990s were the  Gulf War  and its aftermath and Operation Southern Watch in southern Iraq. All active vessels were engaged in both of these to some extent, with Operation Southern Watch continuing until 2003. Most carriers in operation in Operation Desert Shield and Operation Desert Storm played supporting roles, with only Theodore Roosevelt playing an active part in combat operations. Throughout

10400-753: Was launched in accordance with President Obama's announcement on the evening of 7 August that the US would begin airstrikes to protect US personnel and the Yazidis in the region from ISIL attacks. On 23 September 2014 F/A-18 Hornets and Super Hornets from Carrier Air Wing Eight launched from George H.W. Bush in the Persian Gulf to strike at specific targets in Syria such as command-and-control centers, training camps, and weapons depots. On 15 November 2014, George H.W. Bush returned to her homeport in Norfolk, Virginia after

10504-498: Was ordered to the Persian Gulf to protect US interests in Iraq in light of the militant group Islamic State of Iraq and the Levant 's (ISIL) offensive and takeover of several major cities in that country. On 8 August 2014, two F/A-18F Super Hornets launched from the ship and dropped 500-pound (230 kg) laser-guided bombs on an ISIL mobile artillery cannon shelling Kurdish forces outside their capital city, Erbil . The mission

10608-650: Was partly a result of increased space available by the new design of the ships' propulsion systems. A major purpose of the carriers was initially to support the U.S. military during the Cold War . They were designed with capabilities for that role, including using nuclear power instead of oil for greater endurance and the ability to adjust their weapons systems on the basis of new intelligence and technological developments. They were initially categorized only as attack carriers, but ships have been constructed with anti-submarine capabilities since USS  Carl Vinson . As

10712-458: Was permanently affixed to the ship. The ship was modularly constructed, where large sections are assembled and then lifted into place using a large crane. Major milestones in the construction include the bow placement in March 2005, followed by the island placement on 8 July 2006. The 700-short-ton (640 t; 620-long-ton) island was lifted onto the flight deck in a ceremony called " stepping

10816-634: Was scheduled to last through early 2010. The ship was assigned to Carrier Strike Group Two for her first deployment. Under the command of Rear Admiral Nora Tyson , George H.W. Bush , Carrier Air Wing Eight and the four ships of her group departed on her first deployment on 11 May 2011. They sailed across the Atlantic to Britain to participate in Exercise Saxon Warrior , held in the Western Approaches and culminating in
