Tehran / Washington — The United States has unleashed its most secretive weapon in the largest wave of Operation Epic Fury so far, as B‑2 Spirit stealth bombers slip through Iran’s battered air defenses to hammer underground command centers, missile hubs and “ghost” airbases once thought untouchable.

Taking off from undisclosed bases and refuelling in total radio silence, the bat‑wing “Beasts” crossed into Iranian airspace under a blanket of electronic warfare, their radar signatures all but erased. Within minutes, precision “bunker‑buster” bombs began slamming into mountainsides near Kermanshah, Khuzestan and central Iran, collapsing tunnels and buried halls used by the IRGC to shelter missiles and drone fleets.

Residents filmed fireballs erupting from remote ridgelines, followed by hours of secondary explosions as fuel depots and hidden munitions cooked off deep below ground. Iranian state TV blamed “limited intrusions by enemy aircraft,” but unusual communications blackouts around key bases and the sudden silence of several missile brigades suggest the damage runs far deeper.

At the Pentagon, officials call the B‑2 raids “the backbone of Epic Fury,” boasting that “decades of Iran’s underground investments were undone in a single night.” Tehran vows its “underground cities” will be rebuilt and threatens broader missile strikes on U.S. bases and Israeli cities.

Analysts warn that with the B‑2 now fully in play, the conflict has crossed a new threshold: Washington is no longer just degrading Iran’s arsenal from the edges, but driving sledgehammers into the regime’s deepest bunkers — and daring Tehran to find an answer it may not yet have.
