The Global Hawk continues to be a leader in the high-altitude long endurance (HALE) UAV field through continuous upgrades. These have included Active Electronically Scanned Array (AESA) radars, upgraded gimballed sensors, and others. As the RQ-4 fulfills a similar role in strategic reconnaissance and intelligence gathering to the U-2, not much information is available about its contribution to current military efforts.

But as the type continues to be procured and upgraded, it’s fair to say that the Global Hawk-class of UAVs is still the world’s best. Global Hawks have also proven their reliability countless times during the last two decades, and as reliability is a key trait for HALE UAVs, the Global Hawk’s record in that space makes it a world leader.
