US long-range B-2 stealth bombers target underground bunkers of Yemen’s Houthi rebels

The nuclear-capable B-2, which first saw action in 1999 in the Kosovo War, is rarely used by the U.S. military in combat as each aircraft is worth some $1 billion. It has dropped bombs in Afghanistan, Iraq and Libya as well. The aircraft are based at Whiteman Air Base in Missouri and typically conduct long-range strikes from there, though some B-2s were in Australia in September.
