Electromagnetic Aircraft Launching Unit (EMALU)
impractical. The EMALS energy-storage subsystem draws power from the ship and stores it kinetically on rotors of four disk alternators. Each rotor can store more than 100 mega joules, and can be recharged within 45 seconds of a launch, which is much faster than steam catapults. This type of energy storage is ideal for this type of application but
