peace process back on track. This laid out the "framework nation" system to be used in future deployments. The EU returned to the DRC during July–November 2006 with EUFOR RD Congo, which supported the UN mission there during the country's elections. Geographically, EU missions outside the Balkans and the DRC have taken place in Georgia, Indonesia, Sudan, Palestine, and Ukraine–Moldova. There is also a judicial mission in Iraq (EUJUST Lex). On 28 January 2008, the EU deployed its largest and most multi-national mission to Africa, EUFOR Tchad/RCA. The UN-mandated mission involves troops from 25 EU states (19 in the field) deployed in areas of eastern Chad and the north-eastern Central African Republic in order to improve security in those regions. EUFOR Tchad/RCA reached full operation capability in mid-September 2008, and handed over security duties to the UN (MINURCAT mission) in mid-March 2009. The EU launched its first maritime CSDP operation on 12 December 2008 (Operation Atalanta). The concept of the European Union Naval Force (EU NAVFOR) was created on the back of this operation, which is still successfully combatting piracy off the coast of Somalia almost a decade later. A second such intervention was launched in 2015 to tackle migration problems in the southern Mediterranean (EUNAVFOR Med), working under the name Operation SOPHIA. Most of the CSDP missions deployed so far are mandated to support security sector reforms (SSR) in host-states. One of the core principles of CSDP support to SSR is local ownership. The EU Council defines ownership as "the appropriation by the local authorities of the commonly agreed objectives and principles". Despite EU's strong rhetorical attachment to the local ownership principle, research shows that CSDP missions continue to be an externally driven, top-down and supply-driven endeavour, resulting often in the low degree of local participation. Structure The CSDP involves military or civilian missions being deployed to preserve peace, prevent conflict and strengthen international security in accordance with the principles of the United Nations Charter. Military missions are carried out by EU forces established with contributions from the member states' armed forces. The CSDP also entails collective self-defence amongst member states as well as a Permanent Structured Cooperation (PESCO) in which 25 of the 27 national armed forces pursue structural integration. The CSDP structure, headed by the Union's High Representative (HR/VP), Josep Borrell, comprises: the Defence Industry Directorate-General of the European Commission relevant sections of the External Action Service
