The Northrop Grumman B-2 Spirit is an American heavy penetration strategic stealth bomber. It uses a flying wing design (no fuselage and tail which are typical in most aircraft) and radar-absorbent materials to largely decrease its radar cross-section. Due to the inherent stability of the flying wing design, it flies by using Fly-By-Wire technology. It is the most expensive aircraft at $2.1 billion per aircraft in 1997. Hence, with the winding-down of the Cold War, only 21 are built. One crashed in 2008, though the pilots ejected safely.
