An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length As well as the aircraft carrier fleet, the U.S. Navy has nine amphibious assault ships used primarily for helicopters, although these also carry up to.

Navy's modern Nimitz-class aircraft carriers are all about. We'll learn what's on the different decks, take a look at the amazing machines that help launch and land aircraft, and find out a little about daily life on these enormous floating bases.
As we'll see, the modern aircraft carrier is one of the most amazing vehicles ever created. This concept dates back almost as far as airplanes themselves. Within 10 years of the Wright Brothers' historic flight, the United States, the United Kingdom and Germany were launching test flights from platforms attached to cruisers. The experiments proved largely successful, and the various naval forces started adapting existing warships for this purpose. The new carriers allowed military forces to transport short-range aircraft all over the world. For example, the Japanese launched the attack on Pearl Harbor from aircraft carriers.
Today, super aircraft carriers are a crucial part of almost all major U. While the ship itself isn't especially useful as a weapon, the air power it transports can make the difference between victory and defeat. One of the major obstacles of using air power in war is getting the planes to their destination.
To maintain an air base in a foreign region, the United States or any other nation has to make special arrangements with a host country, and then has to abide by that country's rules, which may change over time. 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 which enable the ships to operate aircraft in a more effective anti-submarine warfare role, including the fitting of common undersea picture CUP technology which uses sonar to allow for better assessment of 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 used for constructing ships starting with John C. The final carrier of the class, George H. Bush , was designed as a "transition ship" from the Nimitz class to the replacement Gerald R. Ford class. George H. 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 was Operation Eagle Claw launched by Nimitz in after she had deployed to the Indian Ocean in response to the taking of hostages in the U. Atlantic Fleet ,  Dwight D. Eisenhower relieved Nimitz in this operation after her service in the Mediterranean Sea. During this exercise, two of the ship's F Tomcats shot down two Libyan aircraft in what became known as the Gulf of Sidra incident.
All active vessels were engaged in both of these to some extent, with Operation Southern Watch continuing until Throughout the s and more recently, Nimitz -class carriers have been deployed as part of humanitarian missions. In October , Abraham Lincoln deployed to Somalia to assist UN humanitarian operations there, spending four weeks flying patrols over the area around Mogadishu while supporting U. Theodore Roosevelt flew patrols in support of the Kurds over northern Iraq as part of Operation Provide Comfort in Harry S.

Truman ' s maiden deployment was in November The carrier's air wing flew combat sorties in support of Operation Southern Watch , including a strike on Iraqi air defense sites on 16 February , in response to Iraqi surface-to-air missile fire against United Nations coalition forces. 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 Following the attacks, John C.
All active ships have been involved to some extent in Iraq and Afghanistan since that time. This included the invasion in , as well as providing subsequent support for Operation Iraqi Freedom since then. The carriers have also provided aid after natural disasters. Truman provided aid after Hurricane Katrina later in The Ronald Reagan Carrier Strike Group performed humanitarian assistance and disaster relief operations in the Philippines in June after Typhoon Fengshen , which killed hundreds from the central island regions and the main island of Luzon.
In order to refuel their nuclear power plants, the carriers each undergo a Refueling and Overhaul RCOH once in their service lives. This is also the most substantial overhaul the ships undergo while in service and involves bringing the vessels' equipment up to the standards of the newest ships. The ship is placed in dry dock, and essential maintenance is carried out including painting of the hull below the waterline and replacement of electrical and mechanical components such as valves.
Because of 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 major upgrades to the flight deck, aircraft catapults and combat systems as well as other upgrades such as improved radar systems, although precise details can vary significantly between the ships. The improvements normally take around four years to complete. Because of their status as the largest warships in the U.
Navy, the deployment of an aircraft carrier can fulfill a symbolic role, not just in terms of 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 take place either as a single visit to a country, in which senior naval officers are allowed to observe the operating of the carrier and to interact with its senior officers,  or as part of an international task force.
In addition, carriers have participated in international Maritime security operations , combating piracy in the Persian Gulf and off the coast of Somalia. As on most large warships, there have been several incidents involving the death or injury of one or more crew members, although most have involved freak accidents or failures, such as a man overboard as a result of poor weather. One of the highest-profile incidents was on 26 May , when an EA-6B Prowler crashed on the flight deck of Nimitz , killing 14 crewmen and injuring 45 others.

While this in itself was not found to have directly caused the crash, the findings of the investigation prompted the introduction of mandatory drug testing of all service personnel. In cases of ditched aircraft, pilots have been able to eject safely in several cases. However, fatal aircraft crashes have occurred; in , Lieutenant Kara Hultgreen , the first female F Tomcat pilot, was killed while attempting to land on board Abraham Lincoln during a training exercise.
The fire was caused by unauthorized smoking in an area near improperly stored flammable refrigerant compressor oil.
Nimitz -class carriers were designed to have a year service life. Most of the difference in cost is attributed to the deactivation of the nuclear power plants and 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 the first has entered service as of 22 July to replace Enterprise. Most of the rest of these new carriers are to replace the oldest Nimitz ships as they reach the end of their service lives.
