The Boeing-led team is developing flight-worthy scale and full-size versions of the long-endurance aircraft capable of carrying a 1,000-pound payload while remaining in air for up to five years. Boeing-ledede holdet er ved at udvikle flight-værdigt omfang og i fuld størrelse versioner af lang udholdenhed fly kan bære en 1000-pund nyttelast, mens de resterende i luften i op til fem år. The project codenamed Vulture has been awarded to Boeing by Defense Advanced Research Projects Agency (DARPA). Projektet kodenavnet Vulture har fået tildelt til at Boeing ved Defense Advanced Research Projects Agency (DARPA).

Versa Power Systems, Inc. , a developer of Solid Oxide Fuel Cells (SOFC), has been selected to work with Boeing’s Integrated Defense Systems to develop power generating unit for an ultra-long endurance unmanned aircraft. Versa Power Systems, Inc., en udvikler af Solid Oxide Fuel Cells (SOFC), er blevet udvalgt til at arbejde sammen med Boeings Integrated Defense Systems til at udvikle magt skaber enhed for en ultra-lang udholdenhed ubemandede fly. Solid oxide fuel cells are particularly “power dense,” generating considerably large amounts of electricity from a relatively low-weight package. Solid Oxide brændselsceller er særligt "magt tæt," genererer betydeligt store mængder elektricitet fra en relativt lav vægt pakke. They produce energy continuously as long as the basic building blocks of fuel and air are supplied. De producerer energi kontinuerligt, så længe de grundlæggende byggesten af brændstof og luft er leveret. Fuel cells consist of few moving parts, increasing their reliability over many other choices that might be considered for generating energy in a long-endurance aircraft. Brændselsceller består af få bevægelige dele, at øge deres troværdighed over mange andre valg, som kan anses for at generere energi i en lang udholdenhed fly.

High Altitude Long Endurance Systems are intended to provide uninterrupted intelligence-gathering and assured communications over a fixed area for extended times. High Altitude Long Endurance Systems har til formål at sikre uafbrudt spionage og sikker kommunikation over et bestemt område i længere tid.
