US Drops 2,000-Pound Bunker Busters On Isfahan Ammunition Hub Amid Iran War

ISFAHAN, IRAN — In a dramatic escalation of “Operation Epic Fury,” the United States launched a major airstrike on a critical ammunition facility in Isfahan early Tuesday, March 31, 2026. The operation, which utilized 2,000-pound bunker-buster munitions, targeted deeply buried military infrastructure just hours after President Donald Trump signaled a potential willingness to wind down the month-long conflict.

1. The Strike: Precision and Power

According to a U.S. official cited by the media, the attack involved a high volume of “penetrator munitions” designed to drill through reinforced concrete and rock before detonating.

• The Target: A massive ammunition depot in Isfahan, a city of 2.3 million and a cornerstone of Iran’s military-industrial complex.
• Secondary Blasts: President Trump shared a 31-second uncaptioned video on Truth Social showing a chain of fireballs and massive secondary explosions lighting up the night sky. Officials confirmed the footage captured the destruction of the Isfahan site, where stored munitions reportedly triggered hours of successive detonations.
• Nuclear Link: Isfahan is home to the Nuclear Fuel Research and Production Centre (NFRPC). Intelligence reports suggest Iran may have recently shifted over 500 kg of highly enriched uranium to underground facilities in the region, making it a primary strategic objective for U.S. and Israeli forces.

2. Strategic Context: The “Bunker Buster” Arsenal

While the Isfahan strike used 2,000-pound variants, the U.S. has increasingly deployed its most powerful conventional weapon, the GBU-57 Massive Ordnance Penetrator (MOP), during this campaign.

• Capabilities: The 30,000-pound MOP is designed specifically to destroy hardened nuclear sites and command centers that are immune to standard strikes.
• Delivery: Only the B-2 Spirit stealth bomber can carry these massive munitions, allowing the U.S. to strike deep within Iranian territory while evading sophisticated air defense systems.

3. Regional Triggers: The Dubai Tanker Strike

The Isfahan operation followed an Iranian drone attack on the Kuwaiti VLCC tanker Al-Salmi at approximately 12:10 AM Tuesday.

• The Attack: The fully laden tanker, carrying 2 million barrels of crude, was struck in the Dubai port anchorage area, damaging its hull and sparking a fire.
• Environmental Alert: While all 24 crew members are safe and the fire was extinguished, the Kuwait Petroleum Corp (KPC) warned of a potential oil spill in the Gulf.
• Escalation: This strike on a commercial vessel in a major UAE hub signaled Iran’s intent to expand the war into vital energy corridors, prompting the immediate U.S. retaliatory strike on Isfahan.

4. Trump’s “Exit” Strategy and the Strait of Hormuz

Despite the intensity of the Isfahan strike, reports suggest President Trump is looking for an endgame.

• New Timeline: Trump has reportedly told aides he is willing to end the military campaign even if the Strait of Hormuz remains largely closed, shifting the burden of reopening the waterway to regional allies and diplomacy.
• Goal Realignment: The administration’s focus has shifted toward hobbling Iran’s missile stocks and navy rather than a prolonged effort to pry open the chokepoint, which aides warned could extend the war beyond Trump’s preferred 4–6 week window.
