美国总统特朗普于7月24日表示，美国很可能很快会对伊朗位于纳坦兹核设施附近的地下综合体"皮克斯山"进行军事打击[1]。特朗普声称该地点可能存放铀浓缩离心机，并宣称"他们无能为力"[1]。伊朗随即威胁，若美国打击其核设施将"扩大"战争[1]。
这一地下设施位于伊朗伊斯法罕省，距纳坦兹铀浓缩工厂约2公里[1]。根据华盛顿科学与国际安全研究所的估计，该综合体埋深达80至100米[1]。国际原子能机构总干事格罗西反复表示，检查员从未被准许进入该地点[1]。2020年7月纳坦兹先进离心机组装车间因爆炸受损后，伊朗随即开始建设该地下设施[1]。2025年6月美以空袭后，以色列情报部门评估伊朗可能向该设施转移"数千台"铀浓缩离心机[1]。
伊朗当前拥有约970磅（440公斤）浓度达60%的浓缩铀，远高于民用水平，接近武器级90%的浓度[1]。
U.S. President Trump indicated on July 24 that the United States would likely soon strike an underground complex near Iran's Natanz nuclear facility, known as Pickaxe Mountain, claiming the site may house uranium enrichment centrifuges [1]. In response, Iran threatened to escalate military conflict if the U.S. targets its nuclear installations [1].
The underground facility, located in Isfahan Province approximately two kilometers from the Natanz uranium enrichment plant, presents significant defensive obstacles to any potential strike [1]. The complex is buried 80 to 100 meters deep, according to estimates by the Institute for Science and International Security in Washington [1]. International Atomic Energy Agency Director General Grossi has repeatedly stated that agency inspectors have never been permitted access to the site, leaving its precise purpose unclear [1]. Construction of the facility began following damage to Natanz's advanced centrifuge assembly workshop from an explosion in July 2020 [1].
Following Israeli airstrikes in June 2025, Israeli intelligence assessed that Iran may have transferred "thousands of uranium enrichment centrifuges" to the underground facility [1]. Iran currently possesses approximately 970 pounds (440 kilograms) of uranium enriched to 60 percent concentration, significantly exceeding civilian-use levels and approaching the 90 percent concentration required for weapons-grade material [1]. Trump stated at a White House press conference: "We will very likely strike that area very soon. There's nothing they can do about it" [1].
