The U.S. missile and bombing campaign dubbed 'Operation Midnight Hammer' concluded on June 24, 2025, but a sharp divide has emerged between official claims and intelligence assessments regarding the extent of damage to Iran’s nuclear infrastructure. Defense Secretary Pete Hegseth publicly declared that the attack 'obliterated Iran’s ability to create nuclear weapons,' while CNN and The New York Times, citing multiple anonymous intelligence sources, reported that Iran’s underground nuclear sites may have survived largely intact, potentially delaying the program by only a few months.
The Strike: B-2 Bombers and 30,000-Pound Bunker Busters
The operation involved B-2 Spirit stealth bombers launching from Whiteman Air Force Base in Missouri, flying non-stop to strike three key Iranian nuclear facilities: Fordow, Natanz, and Isfahan. According to reports, the bombers dropped 14 GBU-57 Massive Ordnance Penetrators (MOPs), each weighing 30,000 pounds and designed to penetrate deeply fortified underground bunkers. In addition, a U.S. submarine fired more than two dozen Tomahawk cruise missiles specifically targeting the Isfahan facility. The strikes represented one of the largest deployments of bunker-busting munitions in recent military history.
Official Narrative: 'A Perfect Mission'
In a statement to CNBC, Secretary Hegseth vigorously defended the operation’s effectiveness. 'Based on everything we have seen — and I’ve seen it all — our bombing campaign obliterated Iran’s ability to create nuclear weapons,' Hegseth said. He added: 'Our massive bombs hit exactly the right spot at each target — and worked perfectly. The impact of those bombs is buried under a mountain of rubble in Iran; so anyone who says the bombs were not devastating is just trying to undermine the President and the successful mission.' The White House confirmed the existence of the intelligence assessment cited by CNN but distanced itself from its conclusions, reiterating faith in the Defense Secretary’s characterization.
Intelligence Doubts: 'A Few Months, Tops'
CNN’s report, based on four anonymous sources familiar with a preliminary Defense Intelligence Agency (DIA) review, painted a starkly different picture. 'So the (DIA) assessment is that the U.S. set them back maybe a few months, tops,' one source told CNN. The New York Times independently corroborated the finding, quoting insiders who said the initial classified report concluded that Iran’s underground nuclear sites 'are still standing.' The discrepancy raises serious questions about the actual penetrative power of the MOPs against Iran’s deeply buried facilities, particularly the Fordow enrichment plant, which is embedded inside a mountain and hardened against airstrikes.
Why the Divide? Bunker Busters vs. Deep Bunkers
Analysts point to the inherent difficulty of assessing damage to underground targets. While the GBU-57 can penetrate up to 60 meters of reinforced concrete, Iran has invested heavily in burying its nuclear assets under multiple layers of rock and steel. If the intelligence assessment is accurate, the bombs may have obliterated surface structures and upper levels but failed to reach core centrifuges and stockpiles. Additionally, no independent verification—such as satellite imagery of collapsed entrances or seismic data—has been publicly released, leaving both sides to rely on their own sensor data and interpretations.
Geopolitical Fallout: Trust Under Fire
The conflicting narratives come at a delicate time. The fragile Israel-Iran ceasefire brokered by President Donald Trump remained nominally intact as of Tuesday evening, but the credibility of U.S. military claims could affect future diplomatic leverage. If the intelligence assessment proves correct, the Trump administration may face accusations of exaggerating success to bolster domestic support and deter further retaliation. Conversely, if the bombs did more damage than initial reports suggest, the intelligence community may have erred on the side of caution. Either way, the debate over 'Operation Midnight Hammer' has become as consequential as the physical destruction beneath Iran’s soil, testing alliances and the public’s trust in official accounts.
