The B-2 bomber has a completely different design: It’s one big wing, like a
boomerang.
This flying wing design is much more efficient than a conventional plane. Instead of
separate wings supporting all the weight of the fuselage, the entire craft works to
generate lift. Eliminating the tail and fuselage also reduces drag – the total force of
air resistance acting on the plane.
Greater efficiency helps the B-2 travel long distances in a short period of time. It’s
not the fastest craft around - the military says it’s high subsonic, meaning its top
speed is just under the speed of sound (around 1,000 ft/sec or 305 m/s) – but it can go
6,900 miles (11,000 km) without refueling and 11,500 miles (18,500 km) with one in-
flight refueling. It can get anywhere on the Earth on short notice.
