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.波音公司领导的小组正在研制飞行值得的规模和全尺寸版本的长航飞机可携带1000磅重的有效载荷，而其余的在空气中长达5年。 The project codenamed Vulture has been awarded to Boeing by Defense Advanced Research Projects Agency (DARPA).该项目代号为秃鹫已经获得了波音公司的国防高级研究项目署（ 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. 反之亦然电力系统公司开发的固体氧化物燃料电池（固体氧化物燃料电池） ，已选定与波音综合防御系统公司开发的发电单位的超长距离耐力无人驾驶飞机。 Solid oxide fuel cells are particularly “power dense,” generating considerably large amounts of electricity from a relatively low-weight package.固体氧化物燃料电池特别“权力密集” ，产生相当大量的电力从相对低体重封装。 They produce energy continuously as long as the basic building blocks of fuel and air are supplied.他们不断地产生能量，只要基石，燃料和空气供应。 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.燃料电池是由几个移动部件，提高其可靠性比许多其他的选择，可能被视为产生能源的长航的飞机。

High Altitude Long Endurance Systems are intended to provide uninterrupted intelligence-gathering and assured communications over a fixed area for extended times.高空长耐力系统的目的是提供不间断的情报收集和保证通信领域一个固定的时间延长。
