I am sure they shield it well, but wouldn’t the resultant EMP make the ship just a bit harder to hide?
Possible. Although opposing forces would have to come up with specific detection systems for it, which I am pretty sure nobody has implemented.
The closest type of detection system currently existing would be one of the networks of lightning detectors/locators.
I'd like to think that the E-catapult designers have thought of this already, but who knows?
That’s a really interesting question.
