The RQ-4A Global Hawk is a high altitude, high endurance unmanned aircraft and integrated sensor
system to provide intelligence, surveillance, and reconnaissance (ISR) capability in support of
the Joint Force commander. The system is envisioned to support joint combatant forces worldwide
during peace, crisis and wartime operations. The Global Hawk's exceptional range and endurance
coupled with its ability to provide near-real-time transmission of imagery to multi-service and
joint exploitation make it a true force multiplier. Potential applications of the Global Hawk include
Targeting and Precision Strike Support, Battle Damage Assessment, Enemy Order of Battle Information,
Intelligence Preparation of the Battlefield, and Sensitive Reconnaissance Operations.
The Global Hawk air vehicle can operate at altitudes in excess of 60,000 feet and has
demonstrated endurance of over 30 hours. It can carry sensor payloads of approximately 2,000 pounds.
It carries both Electro-Optical (EO) / Infrared (IR) and Synthetic Aperture Radar (SAR) and is capable
of simultaneous use of EO/SAR or IR/SAR with Ground Moving Target Indicator (GMTI). Air vehicle operation
is essentially autonomous using fail-safe programs with the capability of being reprogrammed in flight
should changes to the mission plan be required. System redundancy for selected systems will greatly reduce
the probability of loss and allow extended time on station while a replacement vehicle is enroute. Global
Positioning System (GPS) aided inertial navigation systems provide the accuracy required for both runway
environment and flight operations.
