Stealth strategic bomber ·First flight 1989 · In service 1997
The Northrop Grumman B-2 Spirit is a stealth strategic bomber whose smooth, tail-less flying-wing shape makes one of the largest aircraft in the sky nearly invisible to radar.
Able to slip through the most heavily defended airspace and strike anywhere on Earth with conventional or nuclear weapons, only twenty-one were ever built — each one among the most expensive aircraft in history.
