In this edited volume, Mackenzie Eaglen brings together top foreign and defense policy voices in Washington to address the ever-growing resource-strategic mismatch evident in US defense policy. This project is designed to provide the administration with immediate and realistic solutions to bolster America's military and restore its flagging strategic and conventional deterrents.

Analysis of the FY 2022 Defense Budget from the CSIS Defense Budget Analysis program provides an in-depth assessment of the Biden administration’s request for national defense funding in FY 2022. It outlines priorities for the ongoing and completed strategic reviews—including the National Defense Strategy, Nuclear Posture Review, Missile Defense Review, and Global Posture Review—and their potential budgetary effects. The report concludes by assessing current congressional action on defense appropriations for FY 2022 and identifying key issues for the FY 2023 budget request.

The proliferation of counterspace weapons across the globe often calls into question what can be done to best protect satellites from attack. This analysis from the CSIS Aerospace Security Project addresses different methods and technologies that can be used by the United States government, and others, to deter adversaries from attack. A wide range of active and passive defenses are available to protect space systems and the ground infrastructure they depend upon from different types of threats. This report captures a range of active and passive defenses that are theoretically possible and discusses the advantages and limitations of each. A group of technical space and national security experts supported the analysis by working through several plausible scenarios that explore a range of defenses that may be needed, concepts for employing different types of defenses, and how defensive actions in space may be perceived by others. These scenarios and the findings that resulted from subsequent conversations with experts are reported in the penultimate chapter of the report. Finally, the CSIS Aerospace Security Project team offers conclusions drawn from the analysis, actionable recommendations for policymakers, and additional research topics to be explored in future work.

Analysis of the FY 2021 Defense Budget from the CSIS Defense Budget Analysis program provides an in-depth assessment of the Trump administration’s request for national defense funding in FY 2021. The analysis addresses overall trends in the defense budget, changes in the FY 2021 request, and issues for Congress and the next administration to consider. It also covers the budgets of the National Nuclear Security Administration and the Space Force.

Since the advent of the space age, a primary constraint on military, commercial, and civil space missions has been the cost of launch. Launching objects into space requires substantial investments in launch systems and infrastructure, which has restricted the market to only a handful of national governments and several large private companies. This study explores the possibility of a space industry significantly less constrained by the cost of access to space.
