Raytheon announced a subcontract from Northrop Grumman valued at up to $104 million to modernize the ground control segment of the U.S. Air Force’s RQ-4 Global Hawk unmanned aircraft. The subcontract is among recent enhancements announced for the high-flying surveillance platform. Last September, the Air Force awarded Northrop Grumman an indefinite-delivery, indefinite-quantity contract worth up to $3.2 billion for Global Hawk development, modernization, retrofit and sustainment activities.
