As U.S. B-2 stealth bombers launched from Whiteman Air Force Base in Missouri on Saturday and later struck Iran's Fordow nuclear site in the largest B-2 operation in U.S. history, Newsweek spoke with Naveed Jamali, the only journalist to fly and film inside all three U.S. bombers, for insight into one of America's most secretive weapons.

The operation marked one of the most direct US military actions against Iran in recent memory. According to Caine, the B-2 bombers dropped 14 GBU-57 bunker-buster bombs, including six that were targeted at Iran’s underground Fordow nuclear facility, while US Navy submarines fired dozens of Tomahawk cruise missiles at other sites.
