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.

Additionally, the US Navy has used the first hydraulic catapults up to and through World War II. Even the USS Enterprise (CV-6) of that era would eventually end up with two H 2-1 catapults capable of launching propeller fighters weighing up to 11,000 lbs. to 70 mph in 73 ft – but the USS Enterprise of World War II would rarely use them. This
