Sky Sentinel is an unmanned aerial vehicle (UAV) airship designed for long-duration operation of an automated surveillance platform.
The airship flies at altitudes up to 10000disp=flipNaNdisp=flip and can remain aloft for up to 18 hours. It carries a sensor suite payload of up to 300lb. The airship is 30sp=usNaNsp=us long and contains 26000disp=flipNaNdisp=flip of helium to provide lift.[1]
A follow-on model—Sky Sentinel 2— is planned to support flying at altitudes up to 10000disp=flipNaNdisp=flip while remaining aloft for up to 26 hours with a 400lb sensor suite.[2]
