B-2 bomber in Iran strike: What makes America's stealth jet so powerful?
Days after intense speculation, the United States officially entered the Israel–Iran conflict by launching a direct military strike on Iranian nuclear sites over the weekend. President Donald Trump confirmed the use of B-2 stealth bombers in the assault, targeting three fortified facilities: Fordow, Natanz, and Esfahan.
Describing the operation as 'a historic moment for the US, Israel, and the world,' Trump said six bunker-buster bombs were dropped on Fordow, and 30 Tomahawk missiles launched at the other two sites. At the heart of this strike was the B-2 Spirit—one of the most secretive and expensive military aircraft in the world.
What is the B-2 stealth bomber and how does it work?
The B-2 Spirit, developed by Northrop Grumman, is a long-range strategic bomber built for penetrating dense air defences undetected. First flown in 1989, it remains a cornerstone of America's stealth strike capabilities.
Its unique flying wing design, radar-absorbent coating, and managed heat emissions make it virtually invisible to radar and infrared detection systems. Northrop Grumman claims its radar signature is as small as 0.001 square metres—roughly the size of a bird.
Why is the B-2 the most survivable bomber in modern warfare?
Unlike conventional bombers, the B-2 is built for deep penetration missions. Its stealth features reduce radar, heat, visual, and acoustic signatures, making it hard to detect even by the world's most advanced defence networks.
With an unrefuelled range of over 6,000 nautical miles (approximately 11,000 km), the aircraft can be launched from bases within the continental United States. With aerial refuelling, its range exceeds 10,000 nautical miles. The B-2 used in the Iran strike reportedly flew a near 37-hour non-stop mission, enabled by both mid-air refuelling and cockpit ergonomics designed for long-duration operations.
Only the B-2 can carry America's largest bunker-buster bomb
A key advantage of the B-2 is its enormous payload capacity—over 40,000 pounds of conventional or nuclear weapons. This includes the Massive Ordnance Penetrator (MOP), a 30,000-pound bomb designed to destroy fortified underground targets like Fordow.
Each B-2 can internally carry two MOPs without compromising stealth. According to defence analysts, it remains the only American aircraft capable of delivering such weapons to deeply buried nuclear infrastructure.
The reported use of six MOPs in the latest strike confirms the mission required the B-2's unique capabilities.
How do pilots manage 37-hour missions aboard the B-2?
The B-2 is equipped with amenities rarely seen in combat aircraft: a bed, toilet, microwave, and mini-fridge. With a two-person crew rotating duties, one pilot can rest while the other flies. These additions are crucial for maintaining alertness and performance during long missions—particularly while deploying precision-guided munitions or executing evasive manoeuvres.
Why are there only 21 B-2 bombers in the world?
Despite its unmatched capabilities, only 21 B-2s were ever built, due to a staggering per-unit cost of over $2 billion. As of 2025, only 19 remain in active service—one crashed and one has been retired.
The aircraft requires unique maintenance facilities, including special hangars for reapplying and testing its stealth coating. Given its expense and maintenance complexity, it is reserved for the most critical strategic operations.
Why the B-2 still matters in the age of drones and hypersonic missiles
Three decades after its debut, the B-2 remains a symbol of strategic airpower. Its role in the Iran strike demonstrates that even in an age of AI warfare, drones, and hypersonics, stealth, precision, and surprise are still the pillars of military dominance.

Days After US Strikes, Iran Confirms Nuclear Facilities "Badly Damaged"
Iran's Foreign Ministry spokesman Esmail Baghaei confirmed Wednesday the country's nuclear facilities had been "badly damaged" in American strikes over the weekend. Speaking to Al Jazeera, Baghaei refused to go into detail but conceded the Sunday strikes by American B-2 bombers using bunker buster bombs had been significant. "Our nuclear installations have been badly damaged, that's for sure," he said. Meanwhile, the fragile ceasefire between Israel and Iran appeared to be holding on Wednesday after a rocky start, giving rise to cautious hope that it could lead to a long-term peace agreement even as Tehran insists it will not give up its nuclear program. The ceasefire took hold on Tuesday, the 12th day of the war between Israel and Iran, with each side initially accusing the other of violating it until the missiles, drones and bombs finally stopped. On Wednesday, US President Donald Trump, who helped negotiate the ceasefire, told reporters at a NATO summit in the Netherlands that it was going "very well." "They're not going to have a bomb and they're not going to enrich," Trump said about Iran. Iran has insisted, however, that it will not give up its nuclear program and in a vote underscoring the tough path ahead, Iranian parliament agreed to fast-track a proposal that would effectively stop the country's cooperation with the International Atomic Energy Agency, the Vienna-based UN watchdog that has been monitoring the Iranian nuclear program for years. Ahead of the vote, Iranian Parliament Speaker Mohammad Bagher Qalibaf criticised the IAEA for having "refused to even pretend to condemn the attack on Iran's nuclear facilities" that were carried out by the United States on Sunday. "For this reason, the Atomic Energy Organisation of Iran will suspend cooperation with the IAEA until security of nuclear facilities is ensured, and Iran's peaceful nuclear program will move forward at a faster pace," Qalibaf told lawmakers. In Vienna, IAEA Director General Rafael Mariano Grossi said he had already written to Iran to discuss resuming inspections of their nuclear facilities. Among other things, Iran claims to have moved its highly enriched uranium ahead of the American strikes and Grossi said his inspectors needed to reassess the country's stockpiles. "We need to return," he said. "We need to engage." Questions Over Effectiveness Of US Strikes The American strikes hit three Iranian nuclear sites, which Trump said had "completely and fully obliterated" the country's nuclear program. From Tehran, Iran's Foreign Ministry spokesman, Esmail Baghaei, confirmed that the strikes on Sunday by American B-2 bombers using bunker-buster bombs had caused significant damage. "Our nuclear installations have been badly damaged, that's for sure," he told Al Jazeera on Wednesday, while refusing to go into detail. Trump's special envoy to the Mideast, Steve Witkoff, said on Fox News late on Tuesday that Israel and the US had now achieved their objective of "the total destruction of the enrichment capacity" in Iran, and Iran's prerequisite for talks - that Israel end its campaign - had also been fulfilled. "The proof is in the pudding," he said. "No one's shooting at each other. It's over." At the NATO summit, when asked about a US intelligence report that found Iran's nuclear program has been set back only a few months, Trump scoffed and said it would at least take "years" to rebuild. Israeli military spokesman Brig. Gen. Effie Defrin said Wednesday his country's assessment was also that Iran's nuclear facilities had been "significantly damaged" and its nuclear program "set it back by years." Grossi said he could not speculate on how bad the damage was but that Iran's nuclear capabilities were well known. "The technical knowledge is there, and the industrial capacity is there," he said. "That no one can deny, so we need to work together with them."

Trump Compares Strikes On Iran To Hiroshima Bombing, Says "It Ended The War"
US President Donald Trump said that the strikes on Iran's nuclear facilities last week had resulted in the "total obliteration" of the country's nuclear capabilities, and had set the country's atomic programme back by "decades". However, according to a report by the Defence Intelligence Agency (DIA), Iran's nuclear facilities that had been struck by the United States, such as Fordo, Natanz and Isfahan, had been damaged, but not destroyed, and could be restored. On Wednesday, at a Nato summit in The Hague on Wednesday, Trump dismissed the intelligence report and compared the US strikes on Iran to the second world war bombings of Hiroshima and Nagasaki. "I don't want to use an example of Hiroshima, I don't want to use an example of Nagasaki, but that was essentially the same thing that ended a war," Trump said at the summit. "This ended [the Israel-Iran] war. If we didn't take [out the nuclear facilities], they would be fighting right now," he added. The bombings that took place during World War II, were intended to force Japan's unconditional surrender. Trump said that the US Defence Intelligence Agency "really don't know" about the damage and further stated that damage to Iran's facilities can be fully gauged only after Israel delivered an assessment. "The intelligence says, 'We don't know, it could have been very severe.' That's what the intelligence says. So I guess that's correct, but I think we can take the 'we don't know'. It was very severe. It was obliteration," Trump added. Trump wrote on Truth Social, "Fake news CNN, together with the failing New York Times, have teamed up in an attempt to demean one of the most successful military strikes in history. The nuclear sites in Iran are completely destroyed! both The Times and CNN are getting slammed by the public!" Dan Caine, the chairman of the US joint chiefs of staff said that although the evaluation suggested that the nuclear sites sustained "severe damage and destruction", final assessments "would take time". The White House Press Secretary Karoline Leavitt said that the report was "flat out wrong" and "a clear attempt to demean President Trump", adding, "Everyone knows what happens when you drop fourteen 30,000 pound bombs perfectly on their targets: total obliteration."
