This book is focused on militarization as the nucleus of EU space policy and the interrelatedness of European security, industrial competitiveness, and military capabilities in the shaping of this policy. The EU and key member states have increasingly joined the US, China and Russia, among others, in regarding space assets as critical military, as well as economic, industrial, and technological, enablers. This book tackles this issue by, first, shedding light on the military aspects of EU space policy, with special emphasis on the security and defence dimensions of projects such as Galileo, Copernicus, Space Situational Awareness, and Satellite Communication. In this context, contributors confront the empirical aspect of developments, including the role of different institutional actors and the involvement of specific member states. Further, the volume analyses the discursive, ideological, normative, and theoretical foundations of the use of space by the EU for strategic purposes,
