Northrop Grumman last month started flight testing the third in a series of sensor payloads intended to enhance the mission capability of the unmanned RQ-4B Block 30 Global Hawk. The manufacturer expects the U.S. Air Force will make a decision on fielding the new MS-177 multi-spectral long-range imaging sensor on Global Hawk by the end of the year.
