The White House and Pentagon have prepared plans to use the massive US bomb known as the “Mother of All Bombs” against military targets in Iran if President Donald Trump orders such an operation.

The weapon, formally known as the Massive Ordnance Air Blast bomb, or MOAB, is the largest non-nuclear weapon in the US arsenal. It weighs more than 30,000 pounds and was used by the US military in 2017 against an Islamic State cave complex in Afghanistan.

A Pentagon mentioned that the Defense Department plans for “a wide range of operational scenarios” to carry out presidential and defense secretary-level orders and ensure the success of military missions.

The White House did not confirm that the plans exist, saying it does not comment on sensitive military plans. A spokesperson said Trump “keeps all options on the table” to prevent Iran from obtaining a nuclear weapon.

The reported preparations come as tensions between Washington and Tehran remain high. Trump has warned that the conflict could escalate if he cannot reach an agreement with Iran, while the United States has continued military operations targeting Iranian capabilities.

Trump has also raised the possibility of strikes against Iranian nuclear facilities, including the deeply buried Pickaxe Mountain site, which analysts believe could be connected to Iran’s nuclear program.

The US and Iran have largely avoided direct attacks against each other in recent weeks following months of US strikes on Iranian targets. However, the Trump administration continues to prepare military options as it seeks to pressure Tehran over its nuclear program.
