AeroSpace, Security and Defence Industries Association of Europe (ASD)

The AeroSpace, Security and Defence Industries Association of Europe (ASD) is the European umbrella trade association for the aeronautics, space, defence, and security industries. Operating as a Belgian international nonprofit association, it brings together national industry associations and major companies to coordinate sector positions, policy engagement, research and innovation priorities, sustainability, safety, skills, supply-chain resilience, and international representation. ASD works with European institutions and aviation bodies and represents European aeronautics manufacturers globally through industry-association cooperation; it is distinct from the separately operating ASD-STAN standards organization.
