Did the US or Israel have schematics and blueprints of the Fodrow nuclear plant? How difficult to penetrate thought the ventilation shafts to hit something critical


Access to Schematics and Blueprints of the Fordow Nuclear Plant
Yes, both the United States and Israel likely had access to detailed schematics and blueprints of Iran's Fordow Fuel Enrichment Plant, primarily due to a 2018 Israeli intelligence operation. Israel's Mossad conducted a raid on a warehouse in Tehran, where they stole a significant archive of documents related to Iran's nuclear program, including detailed designs and diagrams of the Fordow facility (referred to as the Al Ghadir project in some documents). These documents provided insights into the underground structure, including the layout of tunnels, centrifuge halls, and critical infrastructure like ventilation shafts.
The stolen archive, parts of which were made public, included schematics that showed the facility's underground layout, with specifics on the location of ventilation shafts and service-related structures. These documents were analyzed by experts, such as those at the Institute for Science and International Security (ISIS), who used them to map the facility's design onto satellite imagery. This gave both the U.S. and Israel a clear understanding of Fordow's layout, including potential vulnerabilities like ventilation shafts.
Additionally, historical satellite imagery and construction photos from as early as 2009, when the ventilation shaft was being built, provided further intelligence. The U.S. also reportedly constructed a replica of Fordow in the desert and tested the GBU-57 Massive Ordnance Penetrator (MOP) against it, indicating access to detailed structural information to simulate the facility's design.
Difficulty of Penetrating Ventilation Shafts to Hit Critical Components
Penetrating the Fordow facility through its ventilation shafts to hit critical components, such as the centrifuge halls, is considered a highly challenging but strategically viable approach due to the facility's fortified design. Here are the key factors affecting the difficulty:

1. Depth and Fortification:
   
   • Fordow is buried approximately 80–90 meters (262–295 feet) under a mountain, reinforced with concrete, making it one of Iran's most protected nuclear sites.
     
   • Most conventional bunker-buster bombs, including Israel's GBU-28 and BLU-109, can only penetrate up to 6–10 meters of concrete or 25 meters of soil, rendering them insufficient to reach the centrifuge halls directly.
     
     
     
     
     
   • The U.S. GBU-57 MOP, carried exclusively by B-2 stealth bombers, is designed to penetrate up to 61 meters (200 feet) of earth or 18 meters of concrete. Even this bomb may not reach the full depth of Fordow's halls with a single strike, requiring multiple sequential drops to "dig" deeper.
     
   
   
2. Ventilation Shafts as Vulnerabilities:
   
   • Ventilation shafts are considered a critical vulnerability because they provide a direct pathway through the rock to the underground facility, bypassing some of the protective layers.
     
   • Satellite imagery and stolen schematics identified the location of at least one ventilation shaft, which was camouflaged after construction but visible in historical imagery.
     
   • U.S. strikes on June 22, 2025, reportedly targeted these shafts, with satellite imagery showing six craters (two clusters of three) aligned with the ventilation shaft and service structures above the centrifuge halls. Experts suggest that targeting the shafts allowed MOPs to penetrate deeper, as the shafts interrupt the rock's integrity, potentially reaching or damaging the enrichment halls.
     
   • Iran attempted to mitigate this vulnerability by backfilling entrances and possibly covering ventilation shafts with concrete before the U.S. strikes, but the MOPs were able to penetrate these defenses.
     
   
   
3. Challenges in Hitting Critical Components:
   
   • The centrifuge halls, housing approximately 3,000 centrifuges, are the primary critical components at Fordow. These are highly sensitive to shock and vibration, and even if the halls are not completely destroyed, the explosive force of MOPs could render centrifuges inoperable through shockwaves or temperature effects.
     
   • Experts note that penetrating the ventilation shafts could cause significant damage by channeling explosive energy into the underground spaces, potentially destroying equipment or disrupting operations for years. However, irregularities in the mountain's geology could deflect shockwaves, reducing effectiveness.
     
   • Assessments vary on the extent of damage. Some sources, including the Israel Atomic Energy Commission and IAEA Director General Rafael Grossi, suggest the facility was "severely damaged" or "inoperable," with centrifuges likely destroyed. Others, including a leaked U.S. Defense Intelligence Agency assessment, indicate the strikes may have only set back operations by months, suggesting partial survival of critical components.
     
   
   
4. Alternative Approaches:
   
   • Beyond airstrikes, sabotage or commando raids could target ventilation shafts or power supplies to disable the facility. For example, cutting power could cause centrifuges to spin out of control, as seen in previous attacks on Natanz. However, a ground operation to plant explosives inside the shafts would be high-risk and logistically complex.
     
   • Israel has a history of successful sabotage, such as the Stuxnet cyberattack on Natanz, but physical access to Fordow's ventilation shafts would require penetrating a heavily guarded facility near Qom, a sensitive religious site, increasing political and operational risks.
     
   
   

Conclusion: The U.S. and Israel had access to detailed schematics of Fordow, thanks to the 2018 Mossad operation and subsequent intelligence analysis, enabling precise targeting of vulnerabilities like ventilation shafts. Penetrating these shafts with GBU-57 MOPs was a strategic choice to bypass the facility's deep fortification, but it remained a difficult task due to the 80–90-meter depth and geological challenges. While the U.S. strikes in June 2025 likely caused significant damage, possibly rendering the centrifuge halls inoperable, uncertainties remain about the full extent of destruction. Multiple MOP strikes on the ventilation shafts appear to have exploited a key weakness, but complete destruction of critical components is not guaranteed, and Iran may retain some capacity to recover.

I am sure there are doubters, like the press for interest,
Do it again.  Targeting the same holes.........Just to be sure.

Say "thanks for the suggestion press people, do you want us to do it another time?"
