At a glance
- U.S. President Donald Trump has repeatedly threatened to bomb a secret Iranian nuclear facility located in a mountain near Natanz, referred to as "Spitzhackenberg" or "Pickaxe Mountain."
- Satellite imagery suggests the facility, built after a 2020 explosion damaged an above-ground centrifuge plant, may house thousands of centrifuges for uranium enrichment at least 100 meters underground.
- Iran has responded to the threats by warning that an attack on its nuclear sites would escalate the conflict regionally, while U.S. intelligence sources indicate Iran moved enrichment centrifuges into the underground complex.
President Donald Trump has intensified his rhetoric against Iran, specifically targeting a clandestine nuclear facility deep within a mountain near Natanz, dubbed "Spitzhackenberg" or "Pickaxe Mountain." Trump has repeatedly vowed to bomb the heavily fortified complex, stating, "We will probably attack this area very soon. And they can do nothing about it."
The exact nature of the facility remains shrouded in mystery, but speculation, fueled by Israeli intelligence sources cited by The Wall Street Journal, suggests it houses thousands of centrifuges for uranium enrichment. These operations are believed to be situated at least 100 meters below ground, protected by the mountain's mass. Satellite images reveal four tunnel entrances leading into the mountain, indicating a significant underground infrastructure.
Iran's military has countered Trump's threats with a stern warning, asserting that any attack on its nuclear facilities would trigger a regional war. This exchange underscores the escalating tensions surrounding Iran's nuclear program. The "Spitzhackenberg" facility reportedly began construction in 2020, following an explosion at a nearby above-ground centrifuge plant, an incident widely suspected to be a covert U.S.-Israeli operation.
Further complicating the situation, reports indicate that Iran accelerated its work at the mountain site in late 2025 after the U.S. reportedly attacked nuclear facilities in Fordo and Natanz with bunker-busting bombs. Satellite imagery has documented construction activities, including the reinforcement of tunnel entrances. Despite its proximity to previously targeted sites, "Spitzhackenberg" has remained untouched during recent military engagements.
We will probably attack this area very soon. And they can do nothing about it.
