You don’t need to be a genius to figure out that centrifuges installed 70–80 meters underground will be largely unaffected by bombs which are believed to have an effect down to a depth of 60 meters.

Moreover, I read the wiki ( https://en.m.wikipedia.org/wiki/GBU-57A/B_MOP ) that 60m penetration specification is for ~35MPA concrete. And good basalt rocks easily go 100MPA. So if Iranians choose just good Mountain, and there are plenty of them...... Mother earth is really strong some places.

That's probably why they targeted the air duct system. It's already been cut and provides a blast channel.

They probably have blast doors on those and USA made it very clear on Flightradar24 that the bombers are coming, lock the doors.

I would assume that this thing is entirely compartmentalized, so to destroy everything you will need a bomb in every room.

According to wikipedia, US made around 20 of those bombs and Trump used 14 of those. So %70 of the stockpile is gone in one go.

Especially on the main site they dropped 3 bobs per strike location, so at best they could have destroyed 2 compartments with 6 bombs. If those were able to penetrate of course.

Honestly, it looks like it was a show like the one where Trump fights professional fighters on the ring. Just significantly more expensive.

Maybe they should just generate those images in AI, would be much more cost effective propaganda.

And now we've learned that these weapons were purpose designed and built specifically for this mission back during the Obama administration:

As in, the were designed to be dropped on this one particular facility, they're not general purpose weapons.
