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 was because

With the proliferation of electromagnetic launch systems presently being designed, built, or studied, there appears to be no limit to their application. One of the intriguing applications is electromagnetically catapulting aircraft from the deck of an aircraft carrier. The US Navy had foreseen the substantial capabilities of an electromagnetic catapult in the 1940s and built a
This method can not only increase the energy converted in each energy storage and release cycle, but also improve the energy storage capacity of the whole system. In the process of energy conversion, no further power electronic converters are required. Correspondingly, complex control systems for the converters are avoided as well. The

Two crucial technologies that have been successfully developed for electromagnetic catapult are Pulse Power, which controls the electromagnetic catapult's power requirements and ensures precise and dependable launches, and Linear Electric Machine, which produces the electromagnetic force required to launch aircraft.
Electromagnetic catapults have several advantages over their steam-based counterparts. Because the rate of aircraft acceleration is more uniform (and is configurable), stress on the airframe is reduced considerably, resulting in increased safety and endurance and lower maintenance costs for the aircraft.
Electromagnetic systems also weigh less, are expected to cost less and require less maintenance, and can launch both heavier and lighter aircraft than steam catapults. They also take up less space below the flight deck and require no fresh water for their operation, thus reducing the need for energy-intensive desalination.
General Atomics Electromagnetic Systems (GA-EMS) developed the first operational modern electromagnetic catapult, named Electromagnetic Aircraft Launch System (EMALS), for the United States Navy. The system was installed on USS Gerald R. Ford aircraft carrier, replacing traditional steam catapults.
China developed an electromagnetic catapult system in the 2000s for aircraft carriers, but with a different technical approach. Chinese adopted a medium-voltage, direct current (DC) power transmission system, instead of the alternating current catapult system that United States developed.
