Weird. I wonder why.

“Weird. I wonder why”

Because, while a U235 implosion device is larger than a comparable yield Plutonium bomb, it is much smaller than a gun-type weapon and requires far less U235 for a viable warhead.

In short, easier to deliver on a missle, can make more with less.

Not weird at all.
