The European Defence Agency (EDA) is an agency of the European Union that promotes and facilitates integration between member states within the EU's Common Security and Defence Policy . The EDA is headed by the High Representative, and reports to the Council. The EDA was established on 12 July 2004 and is based in the Kortenberg building in Brussels, Belgium, along with a number of other CSDP bodies. All EU member states take part in the agency except Denmark. The Danish parliament has adopted a proposal in favour of the country participating in the EDA. The EDA and the European External Action Service (EEAS) together form the Secretariat of the Permanent Structured Cooperation, the structural integration pursued by 25 of the 27 national armed forces of the EU since 2017.
