EMALS is a shipwide power-distribution problem

Retrofitting electromagnetic catapults requires energy storage, conductors, voltage control, weight distribution, redundancy, and repair arrangements that reach far beyond the flight deck.

Notes

An EMALS launch releases energy quickly, but the ship must first move power from its generators to the storage system and recharge that system for the next launch. A viewer's reported specification changes the working assumption from capacitors to flywheels charged in roughly 45 seconds and discharged in two or three. That cycle shows why electrical distribution matters as much as peak generating capacity. Designers must balance fewer large cables against more smaller cables, weighing cost, installation complexity, weight distribution, redundancy, and maintainability. Bus bars may carry power efficiently but require custom construction and can be harder to replace after damage, while cables offer more familiar repair options. Higher voltage can reduce the conductor size needed for a given power flow, and voltage, current, run length, acceptable voltage drop, and conductor material all enter the calculation. Locating storage near the catapults shortens the high-power path but concentrates heavy equipment and creates its own protection and balance questions. An apparently simple catapult retrofit becomes a shipwide naval-architecture and damage-control problem.
