The same energy is then used to return the carriage to its starting position. An electromagnetic catapult can launch every 45 seconds. Each three-second launch can consume as much as 100 million watts of electricity, about as much as a small town uses in the same amount of time.
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.
Electromagnetic catapult technology already has the ability to launch any aircraft now in the Navy inventory and any the Navy has ordered. With the new launch system’s potential to achieve acceleration forces reaching 14 Gs, human endurance may be one of the few limitations it faces.
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.
So, when the Navy announced their plans to replace their traditional steam-powered catapult launch system with a new Electromagnetic Aircraft Launch System (EMALS), the world took notice. The EMALS promised to be more efficient, more reliable, and more cost-effective than the old steam-powered system.
When complete in 2008, it will be the first catapult to use electro-magnetics to launch manned aircraft. As the Navy’s project manager for the Electromagnetic Aircraft Launch System (EMALS), Sulich’s task is to move the newest catapult technology from development at the research facility to ships at sea.

Developed in the 1950s, steam catapults have proven exceptionally reliable. Carriers equipped with four steam catapults have been able to use at least one of them 99.5% of the time. However, there are a number of drawbacks. One group of Navy engineers wrote: "The foremost deficiency is that the catapult operates without feedback control. With no feedback, there often occurs large transients
