From the Executive Summary: "The Office of the Secretary of Defense (OSD) and the Armed Services have made extensive efforts to incorporate unmanned systems into their existing organization structures, showing the integral importance that unmanned systems considerations represent. [...] The progress in unmanned systems technologies has highlighted the need to transition the focus from specific domains to become domain agnostic. [...] DoD, industry, and academia have advanced technologies, strategies, and standards that challenge the evolution of unmanned systems and their integration into the DoD mission. These major advancements, challenges, and trends can be consolidated into four critical themes, which address foundational areas of interest that will continue to accelerate unmanned systems into the future: Interoperability - Interoperability has historically been, and continues to be, a major thrust in the integration and operation of unmanned systems. [...] Autonomy - Advances in autonomy and robotics have the potential to revolutionize warfighting concepts as a significant force multiplier. [...] Network Security- Unmanned systems operations ordinarily rely on networked connections and efficient spectrum access. [...] Human-Machine Collaboration - If interoperability lays the foundation, then humanmachine collaboration is the ultimate objective."
