It's the most covert submarine in the American arsenal. Since the sub's 2004 launch, experts have speculated that USS Jimmy Carter was designed with classified spy missions in mind. Allegedly, the sub is able to slip into enemy ports undetected and even tap into the underwater fiber-optics of foes to listen in on undersea chatter. USS Jimmy Carter may have done just that last year, when it was quietly deployed to spy on North Korea -- one of the only known missions the sub has ever taken.

What else can USS Jimmy Carter, one of the Navy's three Seawolf-class Submarines, accomplish? Nobody's quite sure, because Navy officials haven't commented on exactly what kinds of tech the seafarer is equipped with. But the Jimmy Carter does boast unprecedented hull space, to store unmanned aerial and undersea vehicles for whatever deadly missions our former president's namesake needs to embark on.
