.@BlackSky_Inc IDs additional damage at Isfahan Nuclear Technology Center, likely from US Tomahawks. The images are taken by their new Gen-3 sats (35cm), so can see a lot more detail. Have to wonder what was so important about the building the US hit at 32.583, 51.824

Digging further into the archival Maxar QuickBird imagery, a rough layout of the visible underground infrastructure at Natanz appears (in green). The strike locations are in red. Notably, the entrance building to these has not yet been targeted by a strike.

Fordow is dramatically different from Natanz, where the Iranians constructed an underground structure and then buried it. All of the construction at Fordow, as seen in Landsat 7 images, was underground. And it was very, very deep. Hence why the US engineer the GBU-57.

How did we get from a bit of remote land in rural Iran to the US bombing what's now the Natanz Nuclear Facility? . Construction began in April 2000. Imagery from the since decommissioned Landsat 7 shows us the construction of the project over time.

What was hit by the US at Natanz? A 2003 image from when @Maxar was known as DigitalGlobe lets us see. The second image, shows what the Iranians built underground at Natanz. And it shows the second crater was targeting a second underground section of that facilities there.

This hole that @MeraMeraska points out is almost 10 feet/a little over three meters. Which makes it the smallest crater generated by US strikes on Iran, so far. It's definitely a crater from a strike, but not convinced it's a crater from a GBU-57 at the moment.

The greater Natanz complex is destroyed. The latest hit, clearly targeted the underground infrastructure (and it's the only one that appears to have attempted to target it).

New @maxar satellite imagery shows large crater at Natanz Nuclear Facility in Iran. It matches the size of the bunker-busting bomb craters at Fordow. The crater is roughly 18 feet/5.5 meters in diameter.

While the hit was successful attacking Fordow, and showing the effectiveness of the US' GBU-57. It's largely unclear whether or not the attack was successful at hitting the actual Iranian nuclear program -- equipment and personnel.

It's important because Iranian senior level sources have told news outlets that Fordow was largely emptied out -- its workers and equipment transferred elsewhere. So why would the Iranians literally try to bury their facility if they thought bunker busters were coming?.

NEWS: Satellite imagery shows that in the lead up to the US attack at Fordow, the Iranians worked to entomb the nuclear facilities entrances. The work began on June 20, and continued through June 21. They only managed to completely cover one of the complex's entrances.

This was the missing piece. In the hours before the attack, Iran essentially entombed Fordow, using bulldozers (first seen by @Maxar on June 21) to cover its entrances with dirt.

@Reuters Like. look at this image. It looks like one of the side entrances into the underground complex is completely covered by dirt. Kinda crazy.

So why are the trucks there? . Well, if you believe what a senior Iranian source told @Reuters, they've moved all the material to a new facility. Which is where the additional sat imagery will come in handy.

Let's take the big trucks outside of Fordow. It's really safe to assume that if the Iranians were moving a significant amount of material or infrastructure out of Fordow, the @IDF / US intel would have caught it. And the @IDF likely would have targeted it in transit.

What's really needed is more imagery from June 20 and June 21 to drill down to what Iran was doing there in the hours ahead of the US strike. Did the Iranians essentially entomb Fordow? Which, to me, is them kind of giving up Fordow. You know it's toast at that point.

That's really important when we analyze post-strike imagery, because we see tunnels with dirt outside of them. Including one entrance, which appears to be entirely covered in dirt.

While the post-strike imagery at Fordow is really important, it's also worth bringing up some imagery from two days ago (also from @maxar). Prior to the US strike, large trucks and bulldozers were seen just outside of the tunnels at the Iranian nuclear facility.

@Maxar Those holes are roughly 13-20 feet/4-6 meters in diameter. Also notable that there's debris at the Fordow facility tunnel mouths.

Here's a closer look at the entry points seen in the @maxar image. Quite incredible that how small of a hole is left given how powerful those bombs dropped by the B2s are.
