Raytheon Company will deploy sustainment and cybersecurity experts around the world to support the ground control systems and onboard sensors used by the U.S. Air Force fleet of RQ-4 Global Hawk remotely piloted aircraft. Raytheon Intelligence, Information and Services will perform the work, which includes providing software upgrades to defend against cyber threats, as part of a $65 million subcontract from the aircraft manufacturer, Northrop Grumman. Raytheon previously announced a $104 million effort to modernize the Global Hawk ground segment, moving payload and aircraft operators into mission control buildings. These new stations replace mission control, and launch and recovery elements previously housed in shelters.
