Commissioned by the U.S. Department of Defense, this book uses disciplined diagnostic methodologies to assess the openness and accessibility of European and U.S. defense markets. The authors also evaluate the evolving European institutions, laws, policies, practices, and arrangements that impact the defense industry. They also propose recommendations for the future.

As the book discusses, a more open and competitive transatlantic defense market can potentially facilitate greater force interoperability and capability acquisition in an era where coalition warfare is the norm. A more competitive market would also encourage greater competition, and the affordability and innovation it brings, in a time of global defense industrial consolidation.
