B-2 Spirit

Its low observability, or "stealth" characteristics - including composite materials, special coatings and flying-wing design - make the B-2 an almost undetectable bomber capable of delivering massive firepower in a short time anywhere in the world. This two-person-crew bomber can travel up to 6,000 nautical miles before refueling.
