An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length flight deck and facilities for carrying, arming, deploying, and recovering aircraft. Typically, it is the capital ship of a fleet, as it allows a naval force to project air power worldwide without depending on local bases for staging aircraft operations. Carriers have evolved since their inception in the early twentieth century from wooden vessels used to deploy balloons to nuclear-powered warships that carry numerous fighters, strike aircraft, helicopters, and other types of aircraft. While heavier aircraft such as fixed-wing gunships and bombers have been launched from aircraft carriers, these aircraft have not landed on a carrier. By its diplomatic and tactical power, its mobility, its autonomy and the variety of its means, the aircraft carrier is often the centerpiece of modern combat fleets. Tactically or even strategically, it replaced the battleship in the role of flagship of a fleet. One of its great advantages is that, by sailing in international waters, it does not interfere with any territorial sovereignty and thus obviates the need for overflight authorizations from third-party countries, reduces the times and transit distances of aircraft and therefore significantly increases the time of availability on the combat zone.
A carrier battle group (CVBG) is a naval fleet consisting of an aircraft carrier capital ship and its large number of escorts, together defining the group. The CV in CVBG is the United States Navy hull classification code for an aircraft carrier.
The People's Liberation Army Navy is the maritime service branch of the People's Liberation Army, and the largest navy per number of ships in the world.
The Nimitz class is a class of ten nuclear-powered aircraft carriers in service with the United States Navy. The lead ship of the class is named after World War II United States Pacific Fleet commander Fleet Admiral Chester W. Nimitz, who was the last living U.S. Navy officer to hold the rank. With an overall length of 1,092 ft (333 m) and a full-load displacement of over 100,000 long tons (100,000 t), the Nimitz-class ships were the largest warships built and in service until USS Gerald R. Ford entered the fleet in 2017.
The Indian Navy is the maritime branch of the Indian Armed Forces. The President of India is the Supreme Commander of the Indian Navy. The Chief of Naval Staff, a four-star admiral, commands the navy. As a blue-water navy, it operates significantly in the Persian Gulf Region, the Horn of Africa, the Strait of Malacca, and routinely conducts anti-piracy operations and partners with other navies in the region. It also conducts routine two to three month-long deployments in the South and East China seas as well as in the western Mediterranean sea simultaneously.
A blue-water navy is a maritime force capable of operating globally, essentially across the deep waters of open oceans. While definitions of what actually constitutes such a force vary, there is a requirement for the ability to exercise sea control at long range.
The Type 052B is a class of guided-missile destroyers in the Chinese People's Liberation Army Navy Surface Force (PLAN). The Type 052B was China's first modern destroyer design and the first Chinese design to incorporate true medium-range air defence capability in the form of Russian Shtil-1 surface-to-air missiles (SAM).
The Type 052C destroyer is a class of guided-missile destroyers in the Chinese People's Liberation Army Navy Surface Force (PLAN). The Type 052C introduced both fixed active electronically scanned array (AESA) radar and vertically launched surface-to-air missiles into PLAN service, making it the first Chinese warship with area air defence capability.
The Islamic Republic of Iran Navy or Iranian Navy, officially abbreviated NEDAJA, is the naval warfare service branch of Iran's regular military, the Islamic Republic of Iran Army (Artesh). It is one of Iran's two maritime military branches, alongside the Navy of the Islamic Revolutionary Guard Corps (IRGC).
A green-water navy is a maritime force that is capable of operating in its state's littoral zones and has limited competency to operate in the surrounding marginal seas. It is a relatively new term, and has been created to better distinguish, and add nuance, between two long-standing descriptors: blue-water navy and brown-water navy.
The People's Liberation Army Navy Surface Force is the surface warfare branch of China's People's Liberation Army Navy (PLAN), consisting of all surface vessels in operational service with the PLAN. The PLAN Surface Force operates 661 ships organized into three fleets: the North Sea Fleet, the East Sea Fleet and the South Sea Fleet.
The Type 071 is a class of Chinese amphibious transport dock ships in service with the People's Liberation Army Navy (PLAN). The Type 071 provides the PLAN with capabilities and flexibility not found in its previous landing ships.
The People's Liberation Army Navy Submarine Force (PLANSF) is the submarine service of the People's Liberation Army Navy. It consists of all types of submarines in operational service organized into three fleets: the North Sea Fleet, the East Sea Fleet, and the South Sea Fleet. Submarines have long been one of the three focuses of the People's Liberation Army Navy, and when the decision was made in late 2006 to concentrate on building other principal surface combatants to strengthen the air defense and to further delay the construction of aircraft carriers due to insufficient air cover, submarines will continue to play the lead dominant role in the assault force for the PLAN. Currently, PLANSF operates a fleet of 66 submarines which include nuclear as well as conventional submarines.
The United States Navy (USN) is the maritime service branch of the United States Armed Forces and one of the eight uniformed services of the United States. It is the largest and most powerful navy in the world, with the estimated tonnage of its active battle fleet alone exceeding the next 13 navies combined, including 11 allies or partner nations of the U.S. as of 2009. It has the highest combined battle fleet tonnage and the world's largest aircraft carrier fleet, with 11 in service, 1 undergoing trials, two new carriers under construction, and six other carriers planned as of 2024. With 336,978 personnel on active duty and 101,583 in the Ready Reserve, the U.S. Navy is the third largest of the United States military service branches in terms of personnel. It has 299 deployable combat vessels and about 4,012 operational aircraft as of July 18, 2023.
Since the 1970s, China's People's Liberation Army Navy (PLAN) has had ambitions to develop and operate aircraft carriers, and since 1985 has acquired four retired aircraft carriers for study; namely, the British-built Australian HMAS Melbourne and the ex-Soviet carriers Minsk, Kiev and Varyag. The Varyag later underwent an extensive refit to be converted into the Liaoning, China's first operational aircraft carrier, which also served as a basis for China's subsequent design iterations.
The Type 095 is a planned class of third-generation nuclear attack submarines for the People's Liberation Army Navy (PLAN) of China. It is anticipated that the Type 095 submarine will have a substantially reduced acoustic signature, within an improved hull design.
Liaoning is a Chinese Type 001 aircraft carrier. The first aircraft carrier commissioned into the People's Liberation Army Navy Surface Force, she was originally classified as a training ship, intended to allow the Navy to experiment, train and gain familiarity with aircraft carrier operations. Following upgrades and additional training in late 2018, Chinese state media announced that the ship would shift to a combat role in 2019.
The Type 055 destroyer is a class of stealth guided-missile destroyers constructed for the Chinese People's Liberation Army Navy (PLAN). It has a multi-mission design; the combination of sensors and weapons provides a main role of area air defence, with anti-submarine warfare capabilities surpassing previous Chinese surface combatants.
Fujian, named after Fujian province, is the third aircraft carrier of the Chinese aircraft carrier programme and the first of the Type 003 class. Built by the Jiangnan Shipyard for the People's Liberation Army Navy (PLAN), Fujian was launched on June 17, 2022 and is currently fitting out as of January 2024. It is China's first CATOBAR aircraft carrier with a fully indigenous design, an integrated propulsion system and three electromagnetic catapults, unlike the ski-jump flight decks of the previous Chinese aircraft carriers.
