MQ-9 Reaper vs RQ-4 Global Hawk
The MQ-9 Reaper is an armed surveillance and strike aircraft; the RQ-4 Global Hawk is a high-altitude, long-endurance intelligence, surveillance and reconnaissance platform. Global Hawk's long-range sensor mission is not a direct substitute for Reaper's precision-strike capability. Comparing their specifications makes sense only after separating these roles.

Figures below come from the linked DroneStrike profiles and retain their configuration qualifiers. Maximum speed, range, endurance and payload are separate published figures, not a single achievable mission configuration. Range is not necessarily combat radius or datalink reach. Missing information is not zero, and a larger figure does not establish combat effectiveness.
Armed surveillance versus strategic-area reconnaissance
Reaper can observe an area and carry cleared precision weapons, allowing surveillance and attack to be combined when the mission permits. Global Hawk is designed around gathering intelligence over large areas from high altitude. Its sensor payload supports reconnaissance rather than a comparable missile or bomb load.
A higher ceiling or longer published range does not make Global Hawk a better attack drone. Conversely, Reaper's weapons do not replace the coverage and collection functions of a dedicated high-altitude ISR platform. The aircraft answer different operational questions.
What Global Hawk's payload figure actually means
In an armed-drone comparison, payload is often interpreted as weapons capacity. That interpretation is inappropriate for RQ-4. Its published payload allowance concerns mission equipment, including sensors whose functions differ by aircraft block and operator.
Global Hawk is a family of configurations, not a single sensor package. Historical U.S. Air Force RQ-4B specifications should not be assigned without qualification to NATO RQ-4D Phoenix aircraft or other related systems. The linked RQ-4 profile explains these distinctions.
Range, altitude and endurance are different measures
The catalog presents Global Hawk's historical USAF range figure and converts nautical miles to kilometres. Reaper's range entry is a separate published catalog figure. Neither entry alone tells a reader the exact time on station over a chosen target, which also requires transit distance, load, reserves and mission conditions.
Global Hawk's jet-powered high-altitude design and Reaper's turboprop design support different flight profiles. Maximum speed and service ceiling help explain that distinction, but they cannot establish whether either aircraft can safely operate against a particular air-defense network.
Choose the mission before choosing the metric
If the question is persistent armed overwatch or precision strike, Reaper is the relevant member of this pair. If the question is long-duration, high-altitude reconnaissance and broad-area collection, Global Hawk is the more appropriate reference. A force may use different ISR and strike systems together rather than selecting one as a universal replacement for the other.
Frequently asked questions
Is RQ-4 Global Hawk an armed drone like MQ-9 Reaper?
No. RQ-4 is an ISR platform. Its sensor payload should not be interpreted as a weapons load comparable to Reaper's.
Which flies higher, Reaper or Global Hawk?
The catalog lists a higher service ceiling for Global Hawk. That reflects a different high-altitude ISR mission, not a general ranking of combat capability.
Are RQ-4B and NATO RQ-4D specifications interchangeable?
No. They are distinct configurations with different mission contexts. Historical U.S. Air Force RQ-4B figures should remain labelled rather than being applied to every Global Hawk-family aircraft.
