  "account": "Iran's underground nuclear facility nestled within Pickaxe Mountain has witnessed a recent uptick in construction activity, according to analysts who examined satellite imagery shared with CNN. The Center for Strategic and International Studies (CSIS) stated that the site's construction has transitioned from excavation to internal building work and exterior reinforcement. Road activity around the facility has increased, as well as the reinforcement of tunnel entrances, paving of internal roads, and the removal of excavated material. CSIS analysts speculate that the site may be intended for centrifuge assembly, enrichment, or other nuclear-weapons-related tasks; however, the continuous construction suggests that the facility may not yet be capable of enrichment activities, if that is its intended purpose.\n\nThe United States has previously considered Pickaxe Mountain as a potential target if the conflict with Iran escalates. The Defense Department recently held a planning session on strikes against Iranian underground facilities, including this one. However, US non-nuclear bombs may struggle to penetrate the granite surrounding the facility, as noted in the CSIS analysis. In fact, four days prior to the US launching Operation Epic Fury, a Defense Threat Reduction Agency manager signed an emergency contract for repairs to an underground test facility in New Mexico, linking the preparations to Iran's war efforts and targeting of deeply buried facilities.\n\nUS military strategists are developing next-generation penetrators to potentially target more deeply buried Iranian sites. Following the successful deployment of Massive Ordnance Penetrator bombs in Iran's Isfahan nuclear site in June 2025, the Pentagon believes the weapon may not be sufficient to destroy the facility if it is further buried. The US is also in the process of creating a successor to the Massive Ordnance Penetrator, with a prototype contract awarded in September 2025. The Air Force is seeking defense industry sources for this new weapon, and the US maintains operational plans to strike Pickaxe Mountain, although it remains uncertain whether existing munitions can penetrate deeply enough to destroy the facility.",
