Early reports said we dropped six of the "penetrators" on Fordo, later reports I have read say 12. Hard to know what is the truth because Trump and his people always fudge/increase the numbers. 

Needless to say, they skipped hitting buildings there, those are shown to be intact, and apparently targeted their bombing based on 2009 photos of the site that potentially showed ventilation shafts to the underground facility. However, other imagery shows convoys of trucks leaving the facility prior to the bombings. So, the Iranians moved stuff and Trump did warn them prior to the bombing that he would be bombing those locations. 

I have to think Trump himself is furious that they did not wipe out the buildings at the facility and those are intact. Everything is image to him, and even if those buildings were empty he would have wanted them to appear destroyed just to make it look good. That did not happen.
