Trebuchet: 4th Century BC China: Similar to the catapult, but uses a swinging arm to launch projectiles. It is usually considered to be stronger than the catapult. [4] Oxybeles: 375 BC Greece
Compared to steam catapults, EMALS can control the launch performance with greater precision, allowing it to launch more kinds of aircraft, from heavy fighter jets to light unmanned aircraft. [21] With up to 121 megajoules available, each one of the four disk alternators in the EMALS system can deliver 29% more energy than a steam catapult's ...
