The Boeing SolarEagle (Vulture II) was a proposed High Altitude, Long Endurance (HALE) unmanned aerial vehicle solar-electric spy plane developed by Boeing Phantom Works.[1]

It was intended to remain airborne for five years at a time without needing to land. It had a wingspan of 393.7 feet (120 meters), and was slated to make its first flight in 2014.[2] It has 20 motors of the same type as the Qinetiq Zephyr designed by Newcastle University. DARPA is funding $90 million for the project with Boeing paying the rest.[3] However, the SolarEagle project was cancelled in 2012.[4]
