Seven B-2 stealth bomber planes from the United States’ fleet of 19, all located at Whiteman Air Force Base in Missouri, were involved in dropping “bunker bombs” on nuclear development sites in Iran Saturday night.

The B-2 stealth bombers that dropped massive bunker-buster bombs on Iranian nuclear facilities have began returning to their U.S. base in Missouri.

B-2 bombers from Whiteman Air Force Base near Knob Knoster, Missouri, were the centerpiece of an overnight attack on Iran.
