They are the most deadly of the Keiju (have no idea what that is) prowling the oceans today.
There are 14 of them that carry about half the nuclear arsenal of the United States.
Each ship carries up to 24 of them. After they are launched as they hit re-entry each splits into 8 independent re-entry vehicle with a 100- or 475-kiloton nuclear warhead which could launch up to 192 and wipe out 24 cities. (24 x 8).
So what's the skinny on this? I had no idea we had suchs let alone they were prowling the oceans.
Oh allegedly they can hit targets 7000 miles away. I do not understand kiloton or keiju but I do understand it is not a playtoy.
