In light of Section 881 of the National Defense Authorization Act for Fiscal Year 2017, which expanded the legal definition of the National Technology and Industrial Base (NTIB) to include the United Kingdom and Australia, this report informs NTIB partners on barriers and opportunities for effective integration. The expansion of the NTIB is based on the principle that defense trade between the United States and its closest allies enables a host of benefits, including increased access to innovation, economies of scale, and interoperability. In order to reap the greatest benefits of a new era of NTIB, this report uses the lessons learned from study of the present state of integration to identify areas of opportunity for policy reforms and greater cooperation.

The U.S. Army currently faces a difficult truth: without changes to its modernization strategy, the Army risks losing qualitative tactical overmatch. A lost procurement decade and recent, significant modernization funding declines have resulted in an Army inventory that remains heavily leveraged on the "Big Five" programs, originally procured in the 1970s and 1980s. Meanwhile, technology proliferation has made potential state and nonstate adversaries increasingly capable; shrinking the U.S. overmatch advantage and in some cases surpassing it. While current and projected future Army modernization funding is below historical averages, necessitating increased modernization funding to ensure continued U.S. qualitative tactical overmatch, the Army's modernization problem cannot be fixed only by increasing modernization funding. Additional funds also need to be accompanied by an updated Army modernization strategy that presents a compelling case for modernization funding and sets clear priorities for fulfilling future operational requirements.

On October 4, 1957, the Soviet Union launched Sputnik 1, the first human-made object to orbit the Earth. Six decades later, space-faring nations face a much different space environment, one that's more diverse, disruptive, disordered, and dangerous. Today's space domain presents a number of asymmetries that differ from other domains, creating a deterrence environment with unique policy implications. Escalation and Deterrence in the Second Space Age, a report from the CSIS Aerospace Security Project, discusses the evolution of space as a contested domain, the changing threats to U.S. space systems, deterrence theory and its applications to the space domain, and findings from a space crisis exercise administered by CSIS in late 2016.


This is the inaugural report in the CSIS Defense Outlook Series, an annual review of what happened in the U.S. Department of Defense in the past year and what CSIS experts are looking for in the next. It is meant to serve as a roadmap to track where the course of policy and actions relating to strategy, budget, forces, and acquisition has run and what curves lie ahead.

In a time of austerity, the U.S. Department of Defense has drawn budgetary savings primarily from reductions in private-sector contracting. The 2000-2012 edition of this report by National Security Program for Industry and Resources (NSPIR) at the Center for Strategic and International Studies (CSIS) examines this trend as well as its broader implications for defense industrial policy. The report analyzes contracting for products, services, and research and development by the U.S. Department of Defense overall and by key components. The 2000-2012 report investigates seven key facets of the defense industrial base and provides detailed answers to pressing acquisition policy questions.

Inflicting Surprise

by Mark F. Cancian

Published 15 April 2021

Great power competition has returned after a generation of absence, and the U.S. military edge over prospective opponents is eroding. Whereas the United States previously could overwhelm adversaries with sheer force, if necessary, it now needs every advantage it can get. This study analyzes how the United States might inflict surprise on its adversaries to gain a strategic advantage. Surprise is one aspect of a broader discussion in the national security literature on innovative operational concepts, which may serve as force multipliers to enable the United States to get more out of existing capabilities. A follow up to CSIS's highly successful 2018 study Coping with Surprise in Great Power Conflicts, this report highlights several components of a successful surprise, including exploiting adversary vulnerabilities, using intelligence and technology, employing secrecy and deception, and doing the unexpected. The report also contains over a dozen vignettes illustrating potential future surprises.

Published 14 September 2021

CSIS senior adviser Mark Cancian annually produces a series of white papers on U.S. military forces, including their composition, new initiatives, long-term trends, and challenges. This report is a compilation of these papers and takes a deep look at each of the military services, the new Space Force, special operations forces, DOD civilians, and contractors in the FY 2021 budget. This report further includes a foreword regarding how the Biden administration might approach decisions facing the military forces, drawing on insights from the individual chapters.


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.


Future NATO Enlargement

by Mark F. Cancian

Published 15 January 2022

Past NATO enlargement helped create a Europe whole, free, and at peace, but future enlargement, should it occur, faces a hostile and militarily revitalized Russia. This report examines the military requirements and resulting budget costs of extending NATO's Article 5 commitment to countries such as Ukraine, Georgia, or Bosnia-Herzegovina, which are actively seeking NATO membership, and Sweden and Finland, about which there has been analysis and speculation about membership. Costs to the United States range from $11 billion per year to defend Ukraine to half a billion dollars or less to defend Sweden. The project recommends that NATO incorporate force requirements and cost considerations into its future decisionmaking.
