Summary

A coordinated U.S. operation employing B-2 stealth bombers and Massive Ordnance Penetrator bunker-busters struck Iran’s Fordow, Natanz, and Isfahan nuclear sites, marking the first combat use of the 30,000‑pound GBU‑57. Satellite imagery and on‑the‑ground reporting indicate severe damage to tunnel entrances, ventilation shafts, and aboveground infrastructure, with additional cruise missile strikes compounding effects. While officials tout major degradation, independent experts caution the program is not destroyed: Iran likely dispersed and safeguarded enriched uranium and retains spare centrifuges, enabling eventual reconstitution. The mission showcased unique U.S. capabilities—long‑range B‑2 sorties and deep‑penetration munitions—yet analysts argue lasting constraints on Iran’s nuclear capacity will require inspections and diplomatic agreements beyond kinetic action.

Key Points

  • B-2 bombers executed a 37-hour mission, dropping GBU-57 MOPs on hardened sites.
  • Imagery shows significant damage at Fordow, Natanz, and Isfahan, but core facilities persist.
  • Experts say Iran likely preserved enriched uranium and can rebuild with stored equipment.
  • Debate persists over MOP effectiveness against deeply buried targets like Fordow.
  • Sustainable limits on Iran’s program likely hinge on inspections and diplomacy, not strikes alone.

America’s huge bunker-busting bomb is not sure to work in Iran

The article argues that America’s Massive Ordnance Penetrator (MOP), a large bunker-busting bomb, may be unable to reliably destroy Iran’s deepest and most fortified nuclear facilities, such as Fordow and parts of Natanz. Despite its size and penetration capability, factors like extreme depth, reinforced rock, multi-layered tunneling, and potential Iranian countermeasures could limit its effectiveness, meaning strikes might damage but not fully eliminate key nuclear infrastructure.

Here’s what the US used to attack Iran | CNNClose icon

CNN reports the US launched a major strike on Iran’s nuclear facilities, deploying the Massive Ordnance Penetrator (MOP) for the first time in combat. Military analyst Cedric Leighton explains the weapon mix used to penetrate and cripple hardened sites. Follow-on segments show before-and-after imagery indicating severe damage, reactions from Iranian officials condemning the attacks, mixed US political responses, and on-the-ground reports from Tehran highlighting injuries and public reaction.

US deploys B-2 bombers to Guam, unclear if related to Mideast tensions: official | Fox News

The U.S. has deployed B-2 stealth bombers from Whiteman AFB to Guam, with officials saying there’s no order to move them further and no clear link to current Iran-Israel tensions. Accompanied by KC-135 tankers, the aircraft could potentially reposition to Diego Garcia, a strategic Indian Ocean base closer to Iran. Analysts note B-2s are critical if targeting Iran’s deeply buried Fordow nuclear site, as they can carry 30,000-pound Massive Ordnance Penetrators—capabilities seen as uniquely American.

Satellites show damage to Iran's nuclear program, but experts say it's not destroyed : NPR

U.S. strikes under “Operation Midnight Hammer” hit three key Iranian nuclear sites (Fordo, Natanz, Isfahan) with bunker-buster bombs and cruise missiles, damaging centrifuge halls, infrastructure, and tunnel entrances. Despite Pentagon claims of “obliterating” Iran’s program, independent analysts Jeffrey Lewis and David Albright say the program is far from destroyed. Satellite imagery shows trucks at Fordo and Isfahan before the attack, suggesting Iran likely moved and possibly sealed off stocks of highly enriched uranium—over 400 kg at 60%—which could be relocated and further enriched at covert sites. While the strikes likely set back operations and equipment, Iran may retain uranium stocks and spare centrifuges, enabling reconstitution. Experts conclude lasting curbs would require renewed inspections and a diplomatic agreement, not strikes alone.

B-2 bomber pilots had toilet, microwave and cooler for snacks on 37-hour Fordow bombing raid

Seven B-2 Spirit bombers flew a 37-hour nonstop mission from Missouri to strike Iran’s Fordow nuclear site—their longest sortie since 2001—dropping 14 GBU-57 Massive Ordnance Penetrators in a tightly coordinated operation with escort and support aircraft and minimal communications. To endure the marathon flight, the two-person crews relied on cockpit amenities including a toilet, microwave, and cooler, and alternated rest in a space that allows one pilot to lie down. The mission marked the first combat use of the 15-ton GBU-57 “bunker buster” bombs.

US Massive Ordnance Penetrator 'bunker buster' bombwas needed to destroy untouched Iran Fordow nuclear facility

The article reports that destroying Iran’s deeply buried Fordow uranium enrichment facility likely required the U.S.-only GBU-57A/B Massive Ordnance Penetrator, a 15-ton “bunker buster” deliverable only by a B-2 Spirit bomber. Experts note its delayed detonation and deep-penetration design were necessary for a site located about 300 feet inside a mountain. While the U.S. has sold lighter bunker busters to Israel, it has not shared the Massive Ordnance Penetrator. The piece situates the weapon’s use within recent U.S. strikes on Iranian nuclear sites and highlights White House oversight of the operation.

Here Are the Three Iranian Nuclear Sites the U.S. Attacked - The New York Times

The U.S. conducted major strikes on three Iranian nuclear sites—Fordo, Natanz, and Isfahan—causing extensive damage. At Fordo, multiple 30,000-pound bunker-buster bombs hit likely ventilation shafts and entrances of the deeply buried enrichment facility, severely degrading but not destroying it. At Natanz, already damaged by Israeli attacks, U.S. strikes created craters above suspected underground enrichment halls, compounding prior destruction of power infrastructure that may have harmed centrifuges. At Isfahan, where near-bomb-grade fuel is believed stored, cruise missiles damaged several aboveground buildings; Israeli strikes had hit related labs days earlier. Officials say it’s too soon to assess whether Iran retains a weapons capability or where enriched uranium is stored; if damage is as severe as indicated, Iran’s program could be set back years, barring undisclosed parallel sites.

Images show damage to Iranian nuclear sites Fordow, Isfahan and Natanz - The Washington Post

Satellite imagery shows significant damage from recent U.S. strikes on three key Iranian nuclear sites—Fordow, Isfahan, and Natanz—revealing destroyed aboveground facilities and visible penetration points from bunker-busting munitions aimed at hardened, underground operations. The visuals provide the first concrete look at the aftermath, though public reaction includes skepticism about the strikes’ overall effectiveness and U.S. claims of extensive degradation.
