The world's most expensive fighter air plane. The B-2 spirit costs betwen $2- $2.5 billion [3.4-4.3 trillion UG Shs.]
This bird is undetectable by radar (stealth), since the engines are embedded right inside the airplane body it makes the B- 2 a quiet aircraft, it just whispers past you! no wonder they named it B- 2 Spirit they can see you, but you can't see them!
