**Deck**: New satellite imagery shows the Islamic Revolutionary Guard Corps carving out an underground facility in mountains near Karaj, west of Tehran, with multiple tunnel portals and new access roads appearing since late May. The construction points to Iran hardening key assets against airstrikes as sanctions, maritime pressure and regional tensions deepen.

Iran is taking more of its most sensitive infrastructure underground. Satellite imagery from May through August reveals a new Islamic Revolutionary Guard Corps (IRGC) complex being hollowed into mountainous terrain near Karaj, west of Tehran, suggesting that key capabilities are being moved into hardened sites built to survive airstrikes and sabotage.

Time‑lapse analysis shows excavation work beginning around 21 May, followed by rapid progress over the summer: new access roads snaking into the hills, multiple likely tunnel entrances carved into slopes, and spoil heaps expanding as rock and earth are removed. The layout, familiar from other IRGC underground projects, points to a facility designed to host high‑value assets that Iran expects to be targeted in any major confrontation. The precise function of the site — whether for missiles, drones, command‑and‑control, or storage — is not yet confirmed in open sources.

For Iranian planners, such complexes are a core part of survival strategy. Moving launchers, munitions, and critical equipment into deep, reinforced tunnels complicates any attempt by Israel, the United States, or regional rivals to neutralize Iran’s strike capabilities early in a conflict. Even if above‑ground bases and depots are hit, buried infrastructure is meant to ensure that Iran can continue to launch missiles and drones and maintain command links under bombardment.

For surrounding communities and the wider population, the stakes cut both ways. On one hand, underground facilities can be sited away from dense urban centers, potentially reducing immediate civilian exposure. On the other, they turn nearby regions into strategic terrain, more likely to be mapped into foreign targeting lists. In a worst‑case scenario, areas near Karaj could find themselves on the flight paths of incoming missiles and bombs aimed at silencing whatever the IRGC has chosen to place underground.

Strategically, the Karaj project fits a broader pattern: as pressure mounts on Iran’s economy and as its currency hits new lows against the dollar, Tehran is still allocating resources to long‑term, capital‑intensive defense projects. Each tunnel blasted and reinforced is a bet that confrontation with the United States and its allies will persist for years, requiring assets that can ride out both sanctions and strikes. It is a concrete answer to sanctions campaigns that target surface‑level infrastructure and supply chains.

For Israel, the United States, and Gulf Arab states, the emergence of yet another hardened IRGC complex adds complexity to already dense target maps. Underground sites typically require specialized munitions, detailed intelligence, and sustained operations to degrade. That raises not only military challenges but political ones: striking such facilities risks escalation, especially when they are closer to large population centers around Tehran rather than in remote border regions.

The takeaway is stark: the more Iran buries, the harder it becomes to imagine a quick or limited exchange that can “solve” the nuclear and missile file by force alone.

The next developments to watch will be changes in the visible footprint at Karaj — signs of ventilation shafts, power infrastructure, or support buildings that might hint at the facility’s purpose — and any parallel uptick in rhetoric or disclosures from Tehran about new missile or drone programs. Foreign intelligence leaks or briefings that start to reference “underground cities” near Tehran more frequently will be another sign that this site, and others like it, have moved higher on the list of Western concerns.
