As commercial technologies become more advanced and widely available, adversaries are rapidly developing capabilities that put our forces at risk. To counter these threats, the U.S. military is developing systems-of-systems concepts in which networks of manned and unmanned platforms, weapons, sensors, and electronic warfare systems interact over robust satellite and tactical communications links. These approaches offer flexible and powerful options to the warfighter, but the complexity introduced by the increase in the number of employment alternatives creates a battle management challenge. Current battle management systems often lack the benefit of automated aids to help comprehend and adapt to dynamic situations.

For decades, the United States has successfully countered the threats of competitor nations by harnessing advanced technologies to create exceedingly robust and capable military platforms. But as advanced technologies have become more readily available to adversaries on commercial markets, the Nation’s focus on ever more complex weapons systems has become not just a strength but also a weakness. Effective as they are, U.S. military systems today are often too expensive to procure in the quantities needed, and may take so long to develop that the electronic components they contain are obsolete by the time they become operational.

As nation-state and non-state adversaries adapt and apply commercially available state-of-the-art technology in urban conflict, expeditionary U.S. forces face a shrinking operational advantage. To address this challenge, a new DARPA program is aiming to create powerful, digital tools for exploring novel expeditionary urban operations concepts—with a special emphasis on coastal cities, where future such battles are deemed most likely to occur. The program will test the new tools and concepts in an integrated virtual environment, with the ultimate goal of developing fluidly composable force packages able to maximize tactical advantage in these complex, urban environments.
The military relies heavily on the Global Positioning System (GPS) for positioning, navigation, and timing (PNT), but GPS access is easily blocked by methods such as jamming. In addition, many environments in which our military operates (inside buildings, in urban canyons, under dense foliage, underwater, and underground) have limited or no GPS access. To solve this challenge, Adaptable Navigation Systems (ANS) seeks to provide GPS-quality PNT to military users regardless of the operational environment.
The continued growth in unmanned, sensor, and networked devices is expected to drive the need for larger, more capable and more diverse communications systems. Among other enhancements, these systems must improve jam-resistance and low probability of detection to keep pace with adversaries’ growing electronic sophistication and must adapt to fast-changing operational environments. By contrast, today’s military communications architectures are static and inflexible.
