Pentagon uses GPS-guided bunker-buster bombs on Iran missile sites

US forces have recently carried out strikes using GPS-guided penetrating bombs against Iranian missile facilities located deep underground, Chairman of the Joint Chiefs of Staff General Dan Caine said.

Speaking at a Pentagon press conference on Tuesday, March 10, Caine stated that bombers from US Strategic Command had dropped “dozens of 900-kilogram GPS-guided penetrating munitions” on deeply buried missile launch sites in Iran.

“Strategic Command bombers recently dropped dozens of 900-kilogram GPS-guided penetrating munitions on deeply buried missile launch sites. Across the entire southern flank. We also struck several unmanned aerial vehicle production plants to deprive them of autonomous capabilities,” Caine said.

Caine and US Defence Secretary Pete Hegseth confirmed that dismantling Iran’s missile launch and production capabilities is currently the United States’ primary military priority.

According to Caine, US strikes are also targeting Iran’s broader military-industrial base, including facilities located underground.

Despite what he described as progress in degrading Iran’s missile capabilities, it remains unclear how Washington plans to address another major concern — Iran’s underground nuclear facilities, particularly sites believed to store highly enriched uranium.

CNN previously reported that Iran’s stockpiles of highly enriched uranium cannot be eliminated through airstrikes alone. The outlet also said that the Trump administration had discussed the possibility of deploying ground forces to retrieve the material from underground storage sites.

However, several current and former US officials told CNN that such an operation would likely require large ground forces rather than a small contingent of American special operations troops.
