In a predawn operation cloaked in secrecy, US B‑2 Spirit stealth bombers have struck deep into Iran, dropping bunker‑buster bombs on underground ballistic‑missile complexes that Washington says are at the core of Tehran’s long‑range strike arsenal.

Defence officials report that multiple B‑2s slipped in from high alтιтude, releasing GPS‑guided 2,000‑ and 5,000‑pound penetrators against “missile cities” buried beneath mountain ridges and desert plateaus. Early satellite imagery shows collapsed tunnel mouths, scorched access roads and secondary explosions rippling through fuel and warhead storage galleries hundreds of metres underground.

The Pentagon is hailing the raid as a “strategic body blow,” claiming command bunkers, launch rails and underground rail systems that shuttle mobile launchers between caverns were all hit. US planners argue Iran’s ability to fire coordinated salvos at Israel, Gulf states and American bases has been “set back years.”

Tehran tells a different story. State media insists key missiles were dispersed before the strikes and vows that “new waves” will prove Iran’s deterrent is alive. Anti‑air defences have been placed on high alert, while Revolutionary Guard units talk of targeting US carriers, bases and energy infrastructure across the region.

What happens next may decide the shape of the war: either Iran absorbs the B‑2 blow and edges toward negotiations—or it gambles that surviving missiles, proxies and drones can still hit back hard enough to make Washington regret taking the fight beneath the mountain rock.
