B-2 Spirit: The legendary stealth bomber with flying wings from Northrop Grumman has been unveiled.
After thirty-five years since its first flight, the B-2 Spirit remains the only operational stealth strategic bomber in the world. Northrop Grumman’s flying wing masterpiece carries a price tag of $2.1 billion per aircraft, has a radar cross-section smaller than a bee, and a combat record that spans from Kosovo in 1999 to Houthi strikes in Yemen in 2025.
What is the B-2 Spirit?
The B-2 Spirit is a stealth strategic bomber with a crew of two and four engines, operated exclusively by the United States Air Force. It made its first flight on July 17, 1989, and entered operational service in April 1997. Today, 19 out of the 21 aircraft built remain active with the 509th Bomb Wing at Whiteman Air Force Base, Missouri. Its distinctive feature is the flying wing design – there is no separate fuselage or tail surface – the entire aircraft is a single continuous wing, significantly reducing radar reflection while increasing internal volume for fuel and weapons.
What does it do?
- Strategic nuclear deterrence – one of the three legs of the U.S. nuclear triad, it carries B61-7/11/12 and B83-1 bombs.
- Penetration of restricted airspace – it can enter enemy air defense networks (S-400, HQ-9) undetected to strike high-value targets.
- Mass conventional strike – 80 bombs weighing 500 pounds or 16 JDAM bombs weighing 2,000 pounds in a single pass.
- Bunker-busting missions – the only platform certified for the GBU-57 MOP (30,000 pounds) for deeply buried facilities.
- Global reach — from Whiteman Air Force Base to any point on Earth without the need for refueling; documented combat missions with a duration of 44 hours round trip.

Frequently Asked Questions
Only 21 were built — development costs spread over very few units; RAM coating requires continuously expensive maintenance; assembling the flying wing without a tail is extremely complex.
Yes: Kosovo 1999, Afghanistan 2001, Iraq 2003, Libya 2011, anti-ISIS operations 2015-2019, and Houthi strikes in Yemen in 2025.
The Cold War ended; the plan for 132 aircraft was first reduced to 75, then to 21. The unit cost exceeded $2 billion and Congress rejected further purchases.
The B-21 Raider. Ellsworth Air Force Base will receive its first operational squadron in 2027; B-2s will be retired during the 2030s as more than 100 B-21s enter service.
The Bottom Line
The B-2 Spirit is considered the most significant piece of strategic air power built in the past half-century. The stealth philosophy of the flying wing has given every country observing it a model for reducing radar cross-section through shape. Turkey learned the lesson and applied it in the ANKA-III unmanned platform — the same logic of the flying wing, unmanned, domestic, and exportable at minimal cost.
