The commentary contained throughout the study is derived in part from interviews with primary sources—drawn from leading think tanks, human rights organizations, technology companies, and academia—representing a range of opinions on the technological feasibility, legality, and policy advisability of deploying UAVs for lethal force purposes. The study also draws extensively on secondary research on these same questions, from sources across the opinion spectrum.
The study finds that there are significant trends taking place in the development of UAV technology relevant to their use for intelligence-surveillance-reconnaissance (ISR) purposes in support of lethal force, and for the exercise of lethal force itself. The technology trends identified through primary source interviews and secondary source analysis include:  a continuing demand for, and development of, UAVs for Intelligence, Surveillance and Reconnaissance (ISR) and munitions deployment purposes;  the extension of the geographic range of UAVs, particularly in the context of their use aboard aircraft carriers, although obstacles may remain with respect to trade-space issues surrounding payload vs. endurance;  UAV designs incorporating greater levels of autonomy, requiring less direct remote piloting by humans;  increasing precision and maneuverability, through innovations such as smaller, lighter-weight UAVs with correspondingly smaller munitions, as well as interest in the use of directed energy as part of the UAV platform; and  increasing proliferation of UAV technology to both state and non-state actors, with potential for “dual-use” capabilities between ISR and weapons deployment.
