As the Department of Defense (DoD) develops and employs an increasingly sophisticated force of unmanned systems over the next 25 years (2007 to 2032), technologists, acquisition officials, and operational planners require a clear, coordinated plan for the evolution and transition of unmanned systems technology. With the publication of this document, individual roadmaps and master plans for UASs, UGVs, and UMSs (defined as Unmanned Undersea Vehicles (UUVs) and Unmanned Surface Vehicles (USVs)) have been incorporated into a comprehensive DoD Unmanned Systems Roadmap. This integrated Unmanned Systems Roadmap is the plan for future prioritization and funding of these systems development and technology, thus ensuring an effective return on the Department's investment. Its overarching goal, in accordance with the Strategic Planning Guidance (SPG), is to guide military departments and defense agencies toward logically and systematically migrating applicable mission capabilities to this new class of military tools. This Roadmap highlights the most urgent mission needs that are supported both technologically and operationally by various unmanned systems. These needs, listed below, should be considered when prioritizing future research, development, and procurement of unmanned systems technology to ensure an effective return on the Department's investment.
