In the nuclear world, if the unthinkable happened, America would launch 70 percent of her nuclear firepower from her fleet of ballistic subs.

They are called the “silent service” for a reason -- so stealth that once the U.S.S. Kentucky leaves port, no one knows where she is.

Equipped with 24 nuclear weapons, the Kentucky can unleash more deadly firepower than the world has ever seen.

I recently was invited aboard the sub and although there was much we couldn’t see, what we did see was eye-opening.
