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 .
A mass driver or electromagnetic catapult is a proposed method of non-rocket spacelaunch which would use a linear motor to accelerate and catapult payloads up to high speeds. Existing and proposed mass drivers use coils of wire energized by electricity to make electromagnets , though a rotary mass driver has also been proposed. [ 1 ]
The Electromagnetic Aircraft Launch System (EMALS) is a type of electromagnetic catapult system developed by General Atomics for the United States Navy. The system launches carrier-based aircraft by means of a catapult employing a linear induction motor rather than the conventional steam piston , providing greater precision and faster recharge ...
The test of the J-35 on Liaoning signified that the fighter is intended to operate not only on catapult-equipped Type 003 but also the older ski-jump (STOBAR) carriers. Analysts also believed the smaller size and lighter weight of the J-35 could provide operational advantages on the Liaoning and Shandong . [ 69 ]
The United States Navy is developing the use of a linear motor-based electromagnetic catapult system called the Electromagnetic Aircraft Launch System (EMALS) with the construction of the Gerald R. Ford-class aircraft carriers, and a similar system has also been developed for the Chinese People's Liberation Army Navy's Type 003 aircraft carrier.
CATOBAR (catapult-assisted take-off but arrested recovery [1] or catapult-assisted take-off barrier arrested recovery [2]) is a system used for the launch and recovery of aircraft from the deck of an aircraft carrier. Under this technique, aircraft launch using a catapult-assisted take-off and land on the ship (the recovery phase) using ...
The Type 004 aircraft carrier is a planned supercarrier of the People's Liberation Army Navy's aircraft carrier programme.It is intended to be an iteration on the preceding Type 003 aircraft carrier, and like the Type 003, it will feature an integrated electric propulsion system that will allow the operation of electromagnetic catapults.

Work was reportedly delayed in June 2017 by EM and steam catapult tests. [18] By November 2017, work had resumed after the PLAN reportedly developing an IEP system to power the EM catapults. [ 19 ] [ 20 ] [ 21 ] The first prefabricated block modules were placed into the dry dock in July 2020, and most of the keel and base hull blocks were in ...
