Northrop Grumman Corporation delivered the Arrays at Commercial Timescales Integration and Validation (ACT-IV) system to the Air Force Research Laboratory (AFRL) and Defense Advanced Research Projects Agency (DARPA). The system is based on an advanced digital active electronically scanned array (AESA) that completed multiple successful demonstrations and acceptance testing at Northrop Grumman test facilities.
