The U.S. Air Force has received new 30,000-pound bombs capable of destroying deep underground bunkers, the Bloomberg news agency reported.
The bombs, designed to be delivered by B-2 stealth bombers, "will meet requirements for the current operational need," U.S. Air Force spokesman Lieutenant Colonel Jack Miller said in a statement to Bloomberg.
The U.S. Air Force reportedly started receiving the bombs in September. The bombs are six times bigger than the U.S. Air Force's current bunker-busters.
According to the Bloomberg report, the Boeing company in August received a $32 million contract for eight of the bombs.
Tensions between the U.S. and Iran rose recently after the release of an IAEA report that found that Iran has been working on developing nuclear weapons since 2003.
The U.S. and Israel have not ruled out conducting military strikes against Iran's nuclear facilities, some of which are located in fortified underground locations.
