SPACE PUBLICATIONS

The 2018 National Defense Strategy and National Space Strategy both reaffirm the vital interests that the United States has in the domain of space. However, space remains an inherently hostile environment that has become congested, contested, and competitive among the nations. What are ways for the U.S. Army to assure the success of its space-dependent warfighting functions in an anti-access/area denial (A2/AD) environment where space systems are degraded for significant periods of time?

After providing some necessary background information on space systems, this monograph addresses this question in three parts. First, it analyzes the space capabilities of potential adversaries as well as the technologies required and the nations that possess such capabilities. Second, it explores the strategic implications of such attacks and their potential effects on elements of national power, and then it concentrates on operational effects if space systems were degraded or made unavailable to the Army and other joint warfighters. Third, it examines current measures that may mitigate the negative effects of adversary A2/AD activities as well as possible alternative space capabilities under development. Finally, it makes recommendations for U.S. defense leadership with regard to strategic and operational opportunities to enhance A2/AD mitigation activities and the effectiveness of U.S. space power writ large.

With growing international awareness of energy security challenges, the promise of space-based solar power for clean and unlimited energy for all humankind is certainly appealing. While significant progress continues in the enabling technologies of such systems, is there compelling evidence that space-based solar power systems will provide the best energy solution? How does the Army’s current approach to incorporating a diverse portfolio of renewable energy sources in distributed locations compare to the potential of enterprise ventures that beam energy from solar collectors in space? 

For over 4 decades, many credible organizations in government and industry have explored the concept of space-based solar power, but their serious studies often conclude that such systems remain on the future horizon, usually at least 10 years away from practical application. While space-based solar power systems may be technically feasible, the author believes there is no compelling evidence that such systems will be economically or operationally competitive with terrestrial power generation systems in use or in development. However, he does find that there may be some utility in the limited application of space-based solar power to enable operations in remote and forward operating locations.

The Army has been involved with space-based military operations for well over a half-century. During this time, space operations have changed from a realm exclusive to scientists and engineers, to highly classified activities largely unknown to the general population, to the unveiling of space-based communication, imagery, surveillance, and environment capabilities that have become a foundation for all modern warfare. Today, such support is so ingrained into daily operations that most soldiers, sailors, airmen, and marines assume it has been, and always will be, available for their use. But with such reliance comes vulnerability that potential adversaries may try to exploit. 

The evolution of Army space operations is well documented in many sources, thus this monograph serves not as a comprehensive history or detailed critique of the myriad accomplishments. Rather, it serves as a primer for current and future space-based operations to provide senior policymakers, decisionmakers, military leaders, and their respective staffs an overall appreciation for existing Army space capabilities and the challenges, opportunities, and risks associated with their use in joint operations.
