The United States Marine Corps (USMC) is advancing future hybrid capabilities involving autonomous unmanned aerial vehicles (UAVs) launched from future vertical take-off and lift (VTOL) piloted (or manned) aircraft for coordinated manned/unmanned operations to enhance a variety of warfi ghting missions. The concept includes launching UAVs from manned aircraft with diff erent payload and capabilities to extend reach while keeping human warfighters further from contested environments. Paramount to these mission sets is the ability to effectively enable the complex human -machine interactions between the USMC pilots and the air-launched UAVs. This paper describes a study conducted by the Naval Postgraduate School focused on the human -machine interactions of future USMC hybrid VTOL aircraft/ UAV coordinated operations. The study applied a systems engineering analysis method called Coactive Design to explore human machine interdependencies and develop initial human-machine teaming (HMT) concepts for this future hybrid warfi ghting concept.
