Aurora Flight Sciences (AFS) is an American aviation and aeronautics research subsidiary of Boeing that specializes in special-purpose unmanned aerial vehicles.

In 1995, Aurora joined the Global Hawk team to build composite fuselage components and tail assemblies of the RQ-4 for Northrop Grumman and the USAF.

In 2008, the DARPA Vulture aimed for a UAV that could stay aloft in the stratosphere for at least five years carrying a 1,000 lb (450 kg) payload: Aurora proposed three drones taking off separately then joining up in flight, to form an efficient flat wing at night, and folding into a Z to optimize solar energy collection.

Aurora won a DARPA CRANE (Control of Revolutionary Aircraft with Novel Effectors) grant to test a small-scale plane that uses compressed air bursts instead of external moving parts such as flaps.
