[Bon mots]

If it were plutonium, it would take even less...
The photo above is of the "Davy Crockett", good old US technology from 1954. The actual bomb itself is just the little "bomb-shaped" piece at the front. The rest is the launcher.

I just saw a mock up of one of those in the "heavy weapons" gallery at the West Point museum. The explanatory note said something like "by 1970 the limitations of the Davey Crocket were clear and it was withdrawn." Like, having it only (at most) 2000 yards away when it goes BANG? Ya think?

That picture make it look like a rocket. The one at West Point was described as being launched from a recoilless rifle of about 150mm IIRC. The person in the background also make the supercaliber part look bigger than it really is. The one I saw was definitely hand luggage size.

Now that I think about it, though, I suspect that what they will ultimately say is that it is "enriched" but not bomb grade. Probably the non-bomb grade material that they use in nuclear plants.
