The first is energy storage. Its not difficult even then to make the electric motors required to accelerate a plane like that, but storing the energy required in something that can charge quickly, not take up huge amounts of space, not require constant replacement, and is able to output a huge amount of power for 2-3 seconds is very difficult.
But an electromagnetic aircraft launch system (EMALS) on the Type 002, China''s second home-grown aircraft carrier, would mean less wear and tear on the planes and allow more aircraft to be ...

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. EMALS was first installed on the lead ship of the Gerald R. Ford-class aircraft carrier
An aircraft catapult is a device used to allow aircraft to take off in a limited distance, typically from the deck of a vessel. They can also be installed on land-based runways, although this is rarely done. They are usually used on aircraft carriers as a form of assisted take off . In the form used on aircraft carriers the catapult consists of ...
