The B-2 bombers was first used against Serbia in the 1999 Kosovo War, later in the Iraq War.[4] In 2023, it landed for the first time in Europe – leaving Norway after training with NATO forces.[5][better source needed]

Operation Midnight Hammer

In the early morning of June 22, 2025, seven USAF B-2 bombers[6] conducted the "Operation Midnight Hammer" to bomb Iran's Fordow and Natanz nuclear sites.[6] They dropped 30,000 pounds of bunker busters, followed by two Tomahawk missile strikes on the Isfahan nuclear site, marking the first use of such bombs[7] and the largest B-2 bomber mission in history ‒ involving 125 aircraft when fighter jets and refueling planes are counted in.[8] Trump said that the Iranian nuclear sites had been "completely and totally obliterated".[7][9]

Issues

change

The bomber is reportedly expensive, sparking controversies in the U.S. Congress, which initially wanted 132 bombers, but reduced it to 21 in the 1990s.[source?] In 2008, a B-2 was destroyed in a crash shortly after takeoff. The crew got out safely.[10] 20 B-2s are being used by the United States Air Force.
