“It doesnt make sense, if they have such a power source, it will provide more security making the US energy independent than keeping it secret on Navy vessels.”
I don’t know what they have or don’t have. I just know they are funding a new type of fusion reactor that promising cheap and safe energy without hazardous radioactive pollution. I also see they want rail guns which, they can barely power one with the two LCS they designed. And those ships have more electrical generating capacity than any other ship of it’s size.
Maybe they are just dreaming. Because honestly some of the ships in the navy strike me as sucking out loud. One 5 inch gun as the main offensive weapon iirc.
I think the single gun is a giveaway that there is something far more powerful on these ships. Probably scalar weapons, probably using the large flat transmissive surfaces on the sides of the upper superstructures.
