An electromagnetic catapult, also called EMALS ("electromagnetic aircraft launch system") after the specific US system, is a type of aircraft launching system. Currently, only the United States and China have successfully developed it, and it is installed on the Gerald R. Ford-class aircraft carriers and the Chinese aircraft carrier Fujian. The system launches carrier-based aircraft by means of a catapult employing a linear induction motor rather than the conventional steam piston. The advantage of the electromagnetic catapult is that it is safer and more reliable because the acceleration process is more uniform and less damaging to the structure of the aircraft compared to the steam catapult.

| - An electromagnetic catapult, also called EMALS ("electromagnetic aircraft launch system") after the specific US system, is a type of aircraft launching system. Currently, only the United States and China have successfully developed it, and it is installed on the Gerald R. Ford-class aircraft carriers and the Chinese aircraft carrier Fujian. The system launches carrier-based aircraft by means of a catapult employing a linear induction motor rather than the conventional steam piston. The advantage of the electromagnetic catapult is that it is safer and more reliable because the acceleration process is more uniform and less damaging to the structure of the aircraft compared to the steam catapult. Its main advantage is that it accelerates aircraft more smoothly, putting less stress on their airframes. Compared to steam catapults, the EMALS also weighs less, is expected to cost less and require less maintenance, and can launch both heavier and lighter aircraft than a steam piston-driven system. It also reduces the carrier's requirement for fresh water, thus reducing the demand for energy-intensive desalination. (en)
