>>63863069 (OP)>gbuโ72 boms to blow up the fordo underground nuclear facilityToo small, the GBU-72 simply can't penetrate deep enough.
The Fordow facility is ~60-80 meters deep, and Iran has apparently shown they can make 30,000PSI concrete, it's unknown if even the GBU-57 (the US's deepest penetrating bunker buster that has only been produced in VERY limited number) can manage to penetrate that deep if they're using hardened concrete.
Supposedly the GBU-57 has a penetration capability of over 60 meters into 5,000 PSI concrete, but if Iran is using 30,000 PSI concrete that would reduce penetration to under 5 meters.
Would be a big egg on face moment if the US decide to strike Fordow with multiple GBU-57's only to leave the facility untouched.
