Donald Trump says the United States is getting ready to hit Pickaxe Mountain, and he wants the world to know it. He talked about taking a "nice big fat shot right in the front door" and warned Iranian leaders to get ready.
Behind the dramatic rhetoric lies a brutal engineering reality. Pickaxe Mountain isn't just another military target on a strike map. It's built inside a mountain ridge that sits 1,608 meters above sea level, buried deeper than Fordow under solid granite. Dropping a bomb on the entrance won't wipe out what's inside.
I've watched military analysts, intelligence officials, and weapons experts wrestle with hardened subterranean sites for years. The public chatter around hitting Pickaxe Mountain misses the core problem. Throwing heavier explosives at a mountain doesn't guarantee you smash what's inside. It just changes how the dirt falls.
Where Pickaxe Mountain Came From and Why Iran Built It
To understand why this specific mountain matters, you have to look back at July 2020. An explosion ripped through the above-ground centrifuge assembly facility at Natanz, destroying Iran's primary site for building advanced uranium enrichment machines. Tehran blamed Israeli sabotage immediately.
Iranian officials didn't rebuild on the surface. Ali Akbar Salehi, then head of the Atomic Energy Organization of Iran, announced that the regime was digging a new, far larger facility deep in the mountains nearby.
They picked a site roughly a mile south of the main Natanz nuclear complex. Local maps call the peak Kūh-e Kolang Gaz Lā, which translates roughly to Pickaxe Mountain. Excavation crews started driving tunnels directly into the granite.

By 2022, satellite imagery showed massive piles of spoil and rock tailings accumulating at the base of the mountain. Independent analysis from the Institute for Science and International Security revealed that the excavation volume went far beyond what a simple centrifuge assembly hall required. Iran wasn't just building a replacement shop. They were constructing a subterranean fortress.
By 2025 and into 2026, perimeter walls, double-layered security fencing, and reinforced concrete portals sealed the mountain off. Iran effectively tied the site into the wider defense grid surrounding Natanz.
What Israeli Intelligence Says Is Hidden Inside
Iran has consistently claimed that Pickaxe Mountain exists solely to build replacement centrifuges. But recent intelligence assessments paint a much more alarming picture.
The Wall Street Journal reported that Israeli intelligence shared fresh findings with American authorities. According to those reports, Tehran moved thousands of operational enrichment centrifuges directly into the deep tunnels of Pickaxe Mountain following previous military exchanges. Fresh reporting indicates Israel also suspects Iran transferred a portion of its 60 percent enriched uranium stockpile into the facility.
That changes the entire strategic equation.
If centrifuges and enriched uranium sit inside Pickaxe Mountain, the facility isn't just a manufacturing plant. It's a fortified operational vault. If the rest of Iran's nuclear infrastructure suffers heavy damage, Pickaxe Mountain functions as the ultimate backup policy.
International Atomic Energy Agency inspectors have never set foot inside the complex. Tehran refuses to grant access. That lack of eyes on the ground means Western military planners rely almost entirely on satellite radar, thermal imaging, and human intelligence to figure out what's happening under the rock.
The Hard Physics of Bunker Busters
Whenever Washington threatens an underground site, observers talk about the GBU-57 Massive Ordnance Penetrator. The MOP is a 30,000-pound precision-guided weapon carried by B-2 stealth bombers. It's engineered specifically to dig through earth and concrete before exploding.
The MOP has physical limits.
Under ideal conditions, a single GBU-57 penetrates roughly 200 feet (about 60 meters) of earth or reinforced concrete.
Geological mapping and satellite excavation data show that the tunnel halls inside Pickaxe Mountain sit anywhere from 80 to over 100 meters (260 to 330 feet) beneath solid granite bedrock.
The math simple doesn't add up for a standard strike.
| Site | Peak Elevation | Estimated Depth | Target Hardness |
|---|---|---|---|
| Fordow | ~960 meters | ~60-80 meters | High (Mountain tunnel) |
| Pickaxe Mountain | ~1,608 meters | ~80-100+ meters | Extremely High (Granite ridge) |
A single bomb strike on the peak won't reach the main halls. Even dropping multiple bombs into the exact same crater—a tactic known as "hole-in-a-hole" bombing—presents massive technical challenges. Debris from the first explosion fills the hole, creating a cushion that absorbs the kinetic energy of the following bomb.
Smashing the heart of Pickaxe Mountain with conventional airpower requires either unprecedented luck or a sustained campaign designed to strip away the mountain layer by layer.
The Difference Between Destroying a Facility and Neutralizing It
Planners don't necessarily have to crush the underground halls to take Pickaxe Mountain off the board. You can neutralize a deep facility without ever touching the centrifuges inside.
Air strikes can focus on specific structural vulnerabilities:
- Collapsing the Entrances: Hitting the east and west tunnel portals with heavy munitions can seal the site. If trucks can't drive in and out, the site becomes a tomb for whatever is inside.
- Severing Power and Ventilation: Centrifuges spin at extraordinary speeds. They require constant, stable electricity and advanced cooling systems. Destroying external power substations, backup generators, and air intake shafts halts operations completely.
- Sealing Support Infrastructure: Access roads, water supply lines, and communications towers sit above ground. Knocking those out isolated the underground teams.
Iran knows this. Satellite imagery from early 2026 shows Iranian construction crews pouring thick concrete overhangs over the tunnel portals and dumping heavy rock and earth directly on top of access points. They are actively engineering the terrain to make sealing the entrances as difficult as possible.
Why Trump's Threats Carry High Risks
Threatening to wipe out Pickaxe Mountain makes for forceful public statements, but military operations against buried sites carry severe unintended risks.
If a strike fails to destroy the deeply buried centrifuges, it leaves Iran with intact, highly enriched nuclear assets buried under collapsed rock. That eliminates any future possibility of IAEA inspections or verification. Once a facility is sealed by rubble without being destroyed, proving what is happening inside becomes almost impossible.
Direct strikes on nuclear-adjacent infrastructure escalate regional conflict. Iranian military commanders have already stated that any attack on Pickaxe Mountain will trigger immediate retaliation against American interests and regional transit routes.
What to Watch Next
As rhetoric around Pickaxe Mountain escalates, watch these specific indicators to see how this standoff unfolds:
- B-2 Bomber Deployments: Look for forward deployments of heavy stealth bombers to bases like Diego Garcia or Fairford. B-2s are the only operational aircraft capable of dropping the 30,000-pound MOP.
- Construction Activity at the Portals: Track commercial satellite images for changes at the east and west tunnel entrances. Additional concrete pours or heavy earthmoving signal that Iran expects an imminent attack.
- IAEA Emergency Statements: Watch for official statements from the IAEA regarding access demands. If international diplomats lose all visibility into Iranian nuclear stockpiles, the push for military action will accelerate rapidly.
Pickaxe Mountain represents a massive engineering challenge for military planners. Dropping bombs on a mountain is easy. Guaranteeing you've eliminated what's inside is another story entirely.
