Operation Midnight Hammer was a large-scale United States military operation conducted on June 22–23, 2025, targeting key nuclear facilities in Iran. The operation marked the largest-ever coordinated use of B-2 Spirit stealth bombers in combat and featured the first known operational deployment of the 30,000-pound GBU-57A/B Massive Ordnance Penetrator (MOP) — a “bunker buster” designed to destroy fortified underground targets.
The mission, led by the U.S. Department of Defense, was aimed at crippling Iran’s nuclear program amid escalating tensions in the Middle East. The operation targeted Iran’s uranium enrichment plants in Fordo, Natanz, and Isfahan. The strikes were carried out using a combination of stealth bombers and submarine-launched cruise missiles, in a mission characterized by deceptive tactics and unprecedented operational secrecy.
Background
In the months leading up to Operation Midnight Hammer, tensions between Iran, Israel, and the United States increased significantly. Iran was accused by Western intelligence of accelerating its nuclear enrichment activities in violation of international agreements. In response to growing threats and a recent escalation of regional hostilities, U.S. officials authorized a direct military strike aimed at key nuclear infrastructure.
Planning and Deception
Operation Midnight Hammer involved a significant element of strategic deception. As part of a diversion, a visible group of B-2 bombers was observed taking off from Whiteman Air Force Base in Missouri. These aircraft served as a decoy, misleading both Iranian air defense systems and global observers. Meanwhile, a separate fleet of seven stealth B-2 bombers departed in secrecy, flying eastward with minimal radio communication and mid-air refueling.
The actual strike force reached Iranian airspace undetected after an approximately 18-hour flight, according to Pentagon officials.
Execution
The operation began late on June 22, 2025, with the coordinated launch of:
-
Seven B-2 Spirit bombers equipped with GBU-57A/B bunker busters
-
Submarine-launched cruise missiles targeting support infrastructure
The B-2s delivered precision strikes on fortified underground facilities believed to house uranium enrichment centrifuges. U.S. military sources described the operation as a “devastating precision strike” with high operational success. However, damage assessments were still ongoing as of June 24.
Iranian Response
Iranian state media and government officials denied any significant damage to nuclear infrastructure and characterized the attack as an act of aggression. Iranian leadership pledged retaliation, increasing fears of further escalation in the region.
Despite Tehran’s official denials, independent satellite imagery suggested structural damage at at least two sites, though the full extent remained unclear.
Strategic Impact
Operation Midnight Hammer marked several significant military and geopolitical developments:
-
First operational use of the Massive Ordnance Penetrator
-
Largest known combat deployment of B-2 stealth bombers
-
Renewed scrutiny of U.S. military intervention policy in the Middle East
-
Potential triggering of retaliatory conflict escalation involving Iran, the U.S., and regional actors such as Israel
The operation is widely regarded as one of the most complex airstrike missions executed by the U.S. military since the 2003 invasion of Iraq.
