Pentagon explores using GBU-43/B bomb against Iranian targets

As of October 15, 2026, reports from CNN indicate that the United States military is drafting operational plans to potentially deploy the GBU-43/B Massive Ordnance Air Blast, widely known as the "mother of all bombs," against Iranian energy infrastructure and nuclear facilities. The planning, initiated at the request of President Donald Trump, follows ongoing discussions regarding a significant escalation in regional conflict.

Key targets reportedly include energy installations and the Pickaxe Mountain, an underground facility near the Natanz nuclear complex, which US and Israeli intelligence believe serves as a storage site. While the GBU-43/B is the most powerful non-nuclear weapon in the American arsenal, military officials cited by CNN have expressed skepticism regarding its effectiveness in achieving specific strategic goals. The reports remain unconfirmed by other agencies like Reuters, and no specific timeline for potential military action has been disclosed.

This development comes amidst heightened tensions between Washington and Tehran. The potential use of such a high-yield weapon marks a significant departure from previous military strategies in the region. There is currently no definitive information on when these plans might be enacted, as officials continue to evaluate the strategic utility of such an strike.
