Electromagnetic catapult in the context of "Aircraft catapult"

An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length flight deck and hangar facilities for supporting, arming, deploying and recovering shipborne aircraft. Typically it is the capital ship of a fleet (known as a carrier battle group), as it allows a naval force to project seaborne air power far from homeland without depending on local airfields for staging aircraft operations. Since their inception in the early 20th century, aircraft carriers have evolved from wooden vessels used to deploy individual tethered reconnaissance balloons, to nuclear-powered supercarriers that carry dozens of fighters, strike aircraft, military helicopters, AEW&Cs and other types of aircraft such as UCAVs. While heavier fixed-wing aircraft such as airlifters, gunships and bombers have been launched from aircraft carriers, these aircraft do not often land on a carrier due to flight deck limitations.

The aircraft carrier, along with its onboard aircraft and defensive ancillary weapons, is the largest weapon system ever created. By their tactical prowess, mobility, autonomy and the variety of operational means, aircraft carriers are often the centerpiece of modern naval warfare, and have significant diplomatic influence in deterrence, command of the sea and air supremacy. Since the Second World War, the aircraft carrier has replaced the battleship in the role of flagship of a fleet, and largely transformed naval battles from gunfire to beyond-visual-range air strikes. In addition to tactical aptitudes, it has great strategic advantages in that, by sailing in international waters, it does not need to interfere with any territorial sovereignty and thus does not risk diplomatic complications or conflict escalation due to trespassing, and obviates the need for land use authorizations from third-party countries, reduces the times and transit logistics of aircraft and therefore significantly increases the time of availability on the combat zone.

Fujian (18; Chinese: 福建舰; pinyin: Fújiàn Jiàn) is a Chinese conventionally powered aircraft carrier serving in the People's Liberation Army Navy (PLAN). It is the third carrier of the Chinese aircraft carrier programme and the first of the Type 003 class (NATO/OSD Fujian class), succeeding the Type 002 Shandong. It is China's first indigenously designed carrier, and its first capable of catapult-assisted take-offs (CATOBAR); previous Chinese carriers used ski-jumps (STOBAR). It is the second carrier in the world (after the United States Navy's Gerald R. Ford) to have electromagnetic catapults (EMALS) for launching carrier-based aircraft. The EMALS of Fujian is powered by a Medium-Voltage Direct Current (MVDC) integrated power system—the first of its kind for an aircraft carrier, stated to be more reliable compared to the AC-based EMALS of the Gerald R. Ford-class. It is also the first aircraft carrier in the world to launch a fifth-generation fighter using the electromagnetic catapult system.

Fujian was built by the Jiangnan Shipyard, launched on 17 June 2022, and started sea trials in May 2024. In 2019, analyst Robert Farley from the U.S. Army War College believed that Fujian would be the "largest and most advanced aircraft carrier ever built outside the United States".
