The U.S. Air Force has awarded Northrop Grumman Corporation a $354 million primarily firm-fixed-price contract to expand their RQ-4 Global Hawk unmanned aircraft system (UAS) fleet by three aircraft.

Global Hawk operates multiple sensors simultaneously to gather intelligence, surveillance and reconnaissance (ISR) data. The new aircraft are Multi-INT models that carry sophisticated imaging and electronic signals sensors capable of collecting multiple types of intelligence from high altitudes for up to 32 hours.
