You screwed up on #1, so stopped there.
“The W68 weighs 367 pounds (166 kg). The warhead’s dimensions are not publicly known, however to fit the maximum load of 14 within the roughly 65-inch-diameter (1,700 mm) Poseidon payload fairing,”
A ton, uh huh.
Give us all a break. I'm just tired of the BS artists out there with their "weather balloon advanced delivery systems". Both the dingbat Iranians and the North Koreans have long-range missiles and the ability to adapt designs to a naval platform. We should be worried about them and nukes, just not harebrained.
I'm not saying they can't do it, but this is the same country that accused us of sending them faulty cars, because one flipped over and a 7th century engineer noticed that there was no separate chassis. (Unibody construction having been missed.)
