The B-2 Spirt strategic bomber is built by Northrop Grumman. The overall cost of the project, materials, testing and training comes to $ 2.8 billion, making it the most expensive airplane ever built. For this price can be purchased dozens of F16 fighters. (Fig. Cecilio Ricardo USAF)
It resembles a more alien vehicle than typical bombers. Northrop B-2 Spirit is one of the most amazing aircraft in aviation history. The “Spirit” structure is based on a flying system that makes it impossible to confuse it with any other aircraft. B2 is capable of carrying nuclear weapons and its surfaces are covered with a substance that absorbs radar waves. It can take off from the airport in the United States and reach every point on the globe.
The very concept of flying wings is not new, Nazi Germany was already working on it at the end of World War II.
