No. 2: Nothrup Grumman B-2 Stealth Bomber
The flying-wing concept was brought into the world of advanced stealth technology by Northrop with the B-2 Bomber.
Coated with special composite laminate and secret paint, the B-2 is almost invisible to radar and more B-2s have been identified as UFOs than any other aircraft. Based in the U.S., B-2s on refueling missions can hit any part of the world. At $2.2 billion per aircraft, the cost is awesome, but so is this aircraft.
