Northrop Grumman RQ-4 "Global Hawk"


Unmanned Aerial Vehicle (UAV)

Unmanned, High-Altitude Surveillance.



Developed during the 1990s, the Tier II program was fast-tracked to fruition due to the events of September 11th, 2001. Today, the Northrop Grumman RQ-4 'Global Hawk' serves in the vital Intelligence-Surveillance-Reconnaissance (ISR) role for U.S. forces and its allies. Its high-altitude, turbofan-powered capabilities supply it the range and performance needed to cover swathes of territory from the relative safety of the skies. The RQ-4 platform remains in line to take over duties from the classic, Cold War-era Lockheed U-2 'Dragonlady' and will remain a fixture of American spying capabilities for the foreseeable future.

Qualities





High-Resolution Surveillance



Advanced surveillance-oriented systems aboard Global Hawk provide for high-resolution results through Synthetic Aperture Radar (SAR) and long-range Electro-Optical/InfraRed (EO/IR) sensor fits - making the RQ-4 an all-in-one spying platform.


Turbofan Performance



The Global Hawk's single turbofan installation gives it combat warplane-like performance, allowing the platform to reach altitudes in excess of 60,000 feet and remain aloft for some 32 hours while reaching cruising speeds in the 350 mile-per-hour range.


Maturing Versatility



With nearly two decades of use under its belt, the Global Hawk product continues to mature as a surveillance platform, research-minded product (pictured), and a new overwater maritime solution ('Triton').


Anytime, Anywhere



The proven Global Hawk has become a critical cog in the USAF war machine where its ISR capability places it at the forefront of all spying actions.
