Iran says it is developing ‘father of all bombs’ as missile arsenal expands
Revolutionary Guards spokesman claims Iran significantly increased its missile stockpile and improved its weapons' range, accuracy and destructive capabilities
TEHRAN (MNTV) – Iran’s Islamic Revolutionary Guard Corps (IRGC) announced Wednesday that it is preparing to introduce a new weapon dubbed the “father of all bombs,” amid continuing tensions with the United States and Israel.
IRGC spokesman Hossein Mohebi said preparations were underway to unveil the weapon, describing it as a new development that would surprise Iran’s adversaries.
“We are in the stage of preparing to unveil the ‘father of all bombs.’ This is something new for the enemy,” Mohebi said, according to Iran’s Young Journalists Club news agency.
He did not disclose the weapon’s specifications, capabilities or expected unveiling date.
The announcement follows remarks by US President Donald Trump on Friday suggesting Washington could deploy the GBU-43/B Massive Ordnance Air Blast Bomb, commonly called the “mother of all bombs,” against Iranian nuclear installations.
The American bomb weighs approximately 21,600 pounds (9,800 kilograms) and ranks among the largest conventional, non-nuclear weapons in the US military’s arsenal.
It was first deployed in Afghanistan in April 2017, during Trump’s first term, against a tunnel network used by ISIS (Daesh) militants.
Mohebi also claimed that Iran has expanded its missile inventory by 50% since its 12-day conflict with Israel in June 2025.
He said Iranian missiles have undergone substantial technological improvements, including greater precision, longer operational ranges and increased destructive power.
However, the spokesman did not release figures supporting the reported expansion or provide technical evidence of the claimed improvements.
The statements come amid renewed tensions following the US-Israeli military offensive against Iran that began on Feb. 28.
Iran retaliated by launching attacks against Israel and American military installations in several Arab countries.
Although Washington and Tehran reached a memorandum of understanding in June and subsequently entered negotiations, diplomatic efforts later broke down.
Disagreements over maritime security and freedom of navigation in the Strait of Hormuz, a strategically important passage for global energy shipments and international trade, contributed to the collapse of the talks.
