In a breathtaking display of stealth and power, the United States carried out “Operation Midnight Hammer” on 22 June 2025, deploying its elite B-2 Spirit bombers to strike Iran’s underground nuclear facilities at Fordow, Natanz and Isfahan.
The mission, lauded by Pentagon brass as the largest and longest B-2 operation in history, relied on the 30,000-pound GBU-57A/B Massive Ordnance Penetrator (MOP)—the world’s heaviest non-nuclear bomb—to penetrate some 200–300 feet of fortified rock and concrete and destroy uranium-enriching centrifuges housed within the Fordow site.
A 37-Hour Marathon Flight
The raid began at Whiteman Air Force Base near Kansas City, Missouri, where seven B-2 bombers and a fleet of aerial refuelling tankers launched on Friday evening.
Over the next 18 hours, the flying wings navigated the Atlantic, Mediterranean and Middle Eastern airspace, undergoing multiple in-flight refuellings to sustain their record-breaking 37-hour round trip—the longest since the Spirit’s historic debut mission in 2001 against Afghanistan.
Alongside them flew a decoy force of B-2s westbound toward the Pacific, designed to confuse Iranian radar and spoil any anticipation of an eastern approach.
Stealth, Silence and Surprise
Maintaining near-complete radio silence for much of the journey, the bomber crews relied on precise navigation and sophisticated electronic-warfare countermeasures.
As the formation neared Iran, U.S. fighter escorts and surveillance aircraft cleared the skies, ensuring the 2-pilot crews could focus solely on the strike.
“Our forces retained the element of surprise throughout,” General Daniel Caine, Chairman of the Joint Chiefs of Staff, declared at a Pentagon briefing, emphasising that no Iranian fighters scrambled nor was a single surface-to-air missile launched.
Unleashing the Massive Ordnance Penetrators
At approximately 2:10 a.m. IRST on Saturday, the lead B-2 released two GBU-57 MOPs on Fordow, followed by a coordinated salvo of 14 in total across Fordow and Natanz within a 25-minute window.
Each MOP, weighing in at 30,000 pounds and priced at over US$500 million apiece, is engineered to burrow hundreds of feet underground before detonating, making it the only conventional munition capable of breaching Fordow’s mountain-hardened bunkers.
Statistical Might and Historical Firsts
Seven B-2 bombers deployed against Iran, with six targeting Fordow and Natanz directly and one pairing with a support aircraft to strike Natanz exclusively.
125 U.S. aircraft in total participated, including aerial refuellers, fighters, surveillance planes and a guided-missile submarine that launched Tomahawk cruise missiles at Isfahan just before the bomber strike.
14 MOPs were employed—the first operational use of this bunker-busting weapon since its development in the early 2000s.
This represented the largest single combat deployment of the B-2 fleet since their induction in 1997.
Each $2 billion stealth bomber features a 172-foot wingspan, onboard amenities—including mini-refrigerators, microwaves and a fold-down resting bunk for one pilot—as well as the capability for ultra-long-range, precision strikes.
A Calculated Message of Deterrence
President Donald Trump took to Truth Social to herald the operation’s success: “There is not another military in the world that could have done this,” he proclaimed, framing the strike as both a punitive blow to Iran’s nuclear ambitions and a stark warning against state-sponsored proliferation.
Defence Secretary Pete Hegseth echoed this sentiment, arguing that “Operation Midnight Hammer” underscored the United States’ restored deterrence posture.
Historical Context and Regional Ramifications
Fordow has long symbolised Tehran’s most protected enrichment site, camouflaged beneath a mountain near the holy city of Qom.
Natanz, meanwhile, houses the bulk of Iran’s operational centrifuges, and Isfahan hosts advanced laser-enrichment facilities.
A successful strike on all three, if confirmed, would set back Iran’s nuclear programme by years—if not entirely dismantle its current capacities.
Satellite imagery released post-raid suggests “extremely severe damage” at Fordow, though full assessments are ongoing.
Iranian officials have yet to confirm the extent of the damage, with state media minimising the impact.
Nonetheless, experts warn of significant geopolitical fallout: a potential spike in regional tensions, disruption of global energy markets and a renewed scramble for diplomatic solutions—or retaliatory reprisals—by Tehran and its proxies.
A New Era of Strategic Reach
“Operation Midnight Hammer” marks a watershed moment in modern airpower, demonstrating the U.S. military’s unparalleled ability to project force across the globe with surgical precision.
By marrying stealth technology, record-breaking endurance and the ferocious destructive power of the MOP, the mission not only targeted Iran’s nuclear strongholds but also redefined the parameters of strategic deterrence in an increasingly volatile Middle East.
