This study uses the English School theoretical perspective in investigating European Integration. The research aims to understand how the European Defence-Industrial integration affect the European integration. By mapping the European Defence industrial block's political intention, and coupling it with the increased strength the block has received through the defence-industrial integration, the paper is able to conclude that the defence-industrial integration has led to the creation of a more integrated European defence-industrial society, that pressures the integration process-structure towards more politics of integration and cooperation.
