It flew over 66 thousand flight hours in Iraq on five aircraft and is directly and indirectly credited with producing the intelligence data that dramatically reduced IED production and deployment.
[1] The Army first deployed Constant Hawk in 2006 as part of a Quick Reaction Capability to help combat enemy ambushes and improvised explosive devices (IEDs) in Afghanistan and Iraq.
[4] Initial work on Constant Hawk began in the early 2000s (decade) at Lawrence Livermore National Laboratory as part of the Sonoma Persistent Surveillance Program, a U.S. Department of Energy effort to monitor nuclear proliferation.
In 2009, BAE Systems provided an additional, infrared payload for Constant Hawk called the Airborne Wide Area Persistent Surveillance Sensor (AWAPSS).
[3] In 2013, the MIT sensor MASIVS was deployed by Constant Hawk increasing pixel counts by an order of magnitude and providing full color imagery processed in real-time on board the aircraft.
