When news broke on June 22, 2025, that the United States had launched B-2 Spirit bunker busters in a high-risk strike on Iran’s fortified nuclear sites, the world took notice. For military experts, the real shock wasn’t just the targets. It was how the U.S. deployed its most secretive aircraft, the B‑2 Spirit stealth bomber, deep into Iranian airspace completely undetected.
The B-2 Spirit: Designed for Deep Strikes
The B‑2 Spirit, commonly known as the “Stealth Bomber”, emerged during the Cold War under a veil of secrecy. The U.S. developed it to ensure the ability to strike anywhere in the world — including against hardened or hidden targets — without detection. This was especially important in a potential nuclear showdown with the Soviet Union.
Northrop Grumman, one of America’s largest defence contractors, built the aircraft to fulfil this mission.
Built in Palmdale: America’s Aerospace Fortress
Most B‑2 components are manufactured at Northrop Grumman’s facility in Palmdale, California. The city lies in the Antelope Valley, separated from the Los Angeles Basin by the San Gabriel Mountains.
This site, known as Plant 42, is one of the most secure aerospace production complexes in the world.
The B‑2 first took flight in 1989. Of the 21 units originally produced, only 19 remain in operational service today.
What Makes the B-2 Spirit Invisible?
The aircraft’s unique “flying wing” design, shaped like a giant boomerang, drastically reduces its radar cross-section. Coupled with radar-absorbing materials and carefully engineered engine exhaust systems that lower heat signature, the B‑2 becomes nearly invisible to radar and infrared sensors.
Range, Altitude, and Firepower
The B‑2 may not be fast; it flies below the speed of sound, but it excels in endurance and stealth.
It can fly over 11,000 kilometres without refuelling and nearly 18,000 kilometres with aerial refuelling.
Cruising at 50,000 feet (15,240 meters), the B‑2 is flown by two pilots seated side-by-side in a highly advanced cockpit.
The bomber carries both conventional and nuclear payloads.
Among its most powerful weapons is the Massive Ordnance Penetrator (MOP), a 30,000-pound bomb capable of breaking through 60 metres of reinforced concrete.
How the B-2 Spirit Stealth Bomber Strike on Iran Succeeded
According to Reuters journalists Phil Stewart and Idrees Ali, the U.S. military used a carefully coordinated mix of stealth, electronic warfare, and deception to breach Iran’s air defences:
1. Radar Evasion
The B‑2’s radar signature is so small that it appears no larger than a bird.
Iran’s Russian-made S-300 air defence system, one of the most advanced globally, failed to detect the bombers until it was far too late.
2. Aerial Refueling
The strike mission began from Whiteman Air Force Base in Missouri, where the U.S. tanker aircraft refuelled the bombers midair over the Atlantic and Middle East, enabling a full round trip without touching down.
3. Electronic Warfare and Decoys
As the bombers approached Iranian airspace, decoy aircraft, likely drones and jets, flew misleading paths toward Guam and the Strait of Hormuz. Simultaneously, electronic warfare units jammed or confused enemy radar, ensuring a clear corridor for the real attack.
4. Precision Navigation
The B‑2 relied on satellite-guided inertial navigation systems rather than GPS alone. These systems allow accurate navigation even if GPS signals are jammed or denied.
5. Midnight Attack
The bombing occurred under cover of darkness, when ground-based observers and thermal surveillance are least effective. The aircraft’s non-reflective black paint further reduced visibility to infrared sensors and human observers alike.
What Happens Next?
U.S. Defence Secretary Pete Hegseth stated that the Pentagon spent months preparing for the possibility of a strike. Once former President Donald Trump gave the go-ahead, the mission came together in just a few weeks.
Now, uncertainty hangs over the Middle East.
Several Gulf states, which host U.S. military bases, remain on high alert. Regional leaders are weighing the risks of an escalating conflict.
To reduce vulnerability, the U.S. military has dispersed their forces across the Middle East, while the security levels for American troops have also been raised.
Hegseth said that the military is fully positioned to defend its assets and to strike back if Iran follows through on its threat of retaliation.
