*This book is in the Rapid Communications in Conflict and Security (RCCS) Series (General Editor: Geoffrey R.H. Burn).

The Office of Net Assessment (ONA) was responsible for carrying out three programs in the Department of Defense from November 1973 until the collapse of the Soviet Union. Net assessments utilize a multidisciplinary approach to defense analysis to capture the dynamics of national or coalition military strengths and weaknesses for comparison with the capabilities of competitors and adversaries.

In this book, essays by experts including a number of individuals who have served in or worked for the ONA in the past, such as Andrew Marshall (Director of the United States Department of Defense's Office of Net Assessment, 1973-2015) and Andrew May (Associate Director of the United States Department of Defense's Office of Net Assessment) offer critical insights on the relative military power of the United States vis-à-vis potential adversaries over time. This book is an invaluable resource for scholars and students in international relations, political science, and conflict and security.
