Are you asking me if the actual device is now small enough to be placed on top of a rocket and launched?
I don’t know. It depends on how powerful the engines for their rockets are.
I’m guessing that they have a nuclear device about the size, weight, and yield of Little Boy. So, that’s, what? About 10,000 lbs and maybe a 15 kiloton yield.
Cheers
PS - Sorry for the late response. I was using the laptop last night and hate the small keyboard for typing. Fired up “The Monster” this morning to respond to you.
