Inside the US 'Bunker Buster' Bombs Used on Iran's Fordow Nuclear Site

The United States executed a precision strike on Iran's heavily fortified Fordow Fuel Enrichment Plant using the Massive Ordnance Penetrator, the world's most powerful bunker buster bomb. Dropped by B-2 Spirit stealth bombers, these bombs penetrate deep underground before detonating, compromising Iran's key nuclear facility and signaling a significant escalation in military capabilities against underground targets.

US Deploys 'Bunker Buster' Bombs Against Iran's Fortified Nuclear Facility

In a striking military operation, the United States deployed advanced "bunker buster" bombs on Iran's most secure nuclear site, the Fordow Fuel Enrichment Plant. This facility, famously buried deep beneath a mountain to shield it from airstrikes, faced unprecedented damage from precision strikes carried out by the US Air Force.

What Are Bunker Buster Bombs?

Bunker buster bombs are specialized munitions engineered to penetrate hardened underground structures before detonating, maximizing internal destruction. Among the most formidable of these is the Massive Ordnance Penetrator (MOP), a US-developed bomb known officially as the GBU-57 A/B.

Key Features of the Massive Ordnance Penetrator:

  • Weight: Nearly 14,000 kilograms, making it one of the heaviest conventional bombs.
  • Design: Crafted with a high-strength steel alloy casing to withstand deep penetration through dense rock and reinforced concrete.
  • Explosive Payload: Approximately 2,400 kilograms, engineered with a delayed detonation mechanism that triggers explosion only after deep penetration.
  • Guidance Systems: Equipped with GPS and inertial navigation for precise targeting accuracy, even in challenging combat conditions.
  • Penetration Capability: Can tunnel through up to 200 feet (around 60 meters) of fortified earth or concrete.

How the Strike Was Executed

The operation utilized the stealthy B-2 Spirit bomber, one of America’s most sophisticated strategic weapons platforms. Its ability to bypass advanced air defenses and deliver pinpoint strikes made it ideal for targeting deeply buried sites like Fordow.

Reports indicate that multiple bunker buster bombs—six of the GBU-57 MOP specifically—were dropped on the facility, seriously compromising the core of Tehran’s nuclear ambitions. While the full extent of the damage to the Fordow plant is still being assessed, officials assert this attack represents a significant blow to Iran's nuclear program.

Strategic Significance

Fordow has long stood as Iran’s "crown jewel" nuclear site, protected by its location within a mountain and heavy fortifications underground. The successful strike signals the US’s capability and resolve to neutralize deeply buried nuclear targets using precision technology and advanced aerial platforms.

According to statements from leadership, three key nuclear sites in Iran were targeted during the operation, with Fordow being the primary focus. This decisive military move underscores the escalating tensions and technological brinkmanship surrounding Iran's nuclear activities.

Conclusion

The deployment of bunker buster bombs, especially the Massive Ordnance Penetrator, marks a significant evolution in modern warfare tactics aimed at overcoming underground defenses. By combining high-tech stealth bombers and unprecedented bomb capabilities, the US has demonstrated its ability to strike critical targets previously considered virtually invulnerable.
