Northrop's flying-wing stealth bomber, which flies from Missouri to targets worldwide with aerial refueling, carrying nuclear or precision weapons.
See it on the Battles & Wars map →What happened
Designed in secret from 1981 to slip past Soviet air defenses, the B-2 first flew in July 1989, as the Cold War was ending. Congress cut the planned 132 bombers to 21, which pushed the cost to about $2 billion each including development. Its tailless flying-wing shape and coatings make it hard to see on radar. It flies from Whiteman Air Force Base, Missouri, refueling in the air. B-2s struck Serbia in 1999, Afghanistan, Iraq, Libya, and Iran's Fordow site in 2025.
Why it matters
It made 'global strike from home' real: a handful of two-person crews from the US heartland can reach defended targets worldwide without overseas bases.
How we know
Air Force records and public budgets, Government Accountability Office cost reviews, official accounts of each strike, and the investigation of a 2008 crash on Guam.
Still debated
How detectable the B-2 is to newer low-frequency radars is classified and debated; its successor, the B-21 Raider, first flew in 2023.
Connections (4)
▸Operation Midnight Hammer (US strikes on Iran's nuclear sites) was flown by B-2 Spirit stealth bomberWell documented
The connection
Only the B-2 could carry the 30,000-pound GBU-57 'bunker buster' meant to reach Iran's deeply buried enrichment halls. Seven B-2s flew about 18 hours from Missouri, refueling in the air, and dropped 14 of the bombs on Fordow and Natanz, while submarine-launched Tomahawks hit Isfahan.
When and how
Whiteman Air Force Base, Missouri, to Iran, June 21–22, 2025; announced by President Trump and detailed by Joint Chiefs chairman General Dan Caine.
How we know
Pentagon briefings with maps and timelines, commercial satellite images of the sites, and Iranian statements confirm the strike itself.
Debates and open questions
The damage is disputed: US leaders said the program was 'obliterated'; a leaked preliminary intelligence estimate suggested a setback of months; Iran acknowledged serious damage.
▸B-2 Spirit stealth bomber first saw combat in the Kosovo War and NATO bombingWell documented
The connection
The B-2 made its combat debut on the first night of NATO's bombing. Crews flew round trips of about 30 hours from Missouri, dropping new GPS-guided JDAM bombs in any weather. In about 50 sorties, a tiny share of NATO missions, they struck many key fixed targets.
When and how
Whiteman Air Force Base, Missouri, to Serbia, March 24 – June 1999; the 509th Bomb Wing.
How we know
Air Force mission records and NATO statements document the sorties; the long flights were publicly reported at the time.
Debates and open questions
A B-2 strike hit China's embassy in Belgrade on May 7, killing three; the US blamed an outdated map, while many in China doubt it was an accident.
▸B-2 Spirit stealth bomber flew record 44-hour missions in the War in Afghanistan (2001–2021)Well documented
The connection
In the opening days of the war in October 2001, B-2s flew from Missouri to Afghanistan, bombed Taliban and al-Qaeda targets, landed at Diego Garcia in the Indian Ocean to swap crews, and flew home. One mission lasted about 44 hours, the longest combat flight on record.
When and how
Whiteman Air Force Base to Afghanistan and Diego Garcia, October 2001; crews of the 509th Bomb Wing.
How we know
Air Force records and crew interviews document the flights; the Air Force cites the 44-hour mission as a record.
Debates and open questions
Crew fatigue on such flights raised safety questions; how much the early bombing mattered versus special forces and Afghan allies on the ground is debated.
▸Northrop (later Northrop Grumman) and the B-2 built the B-2 Spirit stealth bomberWell documented
The connection
Northrop won the secret Advanced Technology Bomber contract in 1981 with a flying-wing design, reviving Jack Northrop's 1940s idea. The B-2's shape and materials make it very hard to see on radar. It first flew in 1989. The Air Force planned 132 but bought only 21 as the Cold War ended and costs climbed to about $2 billion per plane.
When and how
Palmdale, California, 1981–2000; Northrop as prime contractor, with Boeing and Vought building major sections.
How we know
Air Force and congressional cost reports, and the public rollout in November 1988.
Debates and open questions
Whether the B-2's cost was worth it, with only 21 built, is debated; supporters point to its unique long-range strike role.
