You can’t destroy a Uranium stockpile with bombs. It’s a chemical element. Sweep it up and seive out the dirt and you’re back in business.

I went back to take a look at the math from those early studies, and I found it actually was fairly straightforward. The so-called penetration equations have existed since the 1960s and depend on a limited number of factors, including the shape of the nose cone, the weight and diameter of the weapon, the speed at which it hits the ground, and — crucially — the type of earth it gets dropped on.
“It depends enormously on the kind of rock,” says Raymond Jeanloz, a professor at the University of California, Berkeley and one of the original authors of the 2005 National Academies Study on earth penetrators.
When I ran the calculations, using a key equation from that study, I found out that the GBU-57 could go up to 80 meters (262 feet) underground if it was dropped in silty clay.
In medium-strength rock, things looked far different. The GBU-57 could only go around 7.9 meters (about 25 feet) beneath the earth — far short of the 60 meters claimed by the infographics.
