The Permanent Structured Cooperation (PESCO) is the part of the European Union (EU) security and defence policy (CSDP) in which 26 of the 27 national armed forces pursue structural integration (the exception being Malta). Based on Article 42(6) and Protocol 10 of the Treaty on the European Union, introduced by the Treaty of Lisbon in 2009, PESCO was initiated in 2017. The integration into PESCO is through projects which launched in 2018.
Together with the Coordinated Annual Review on Defence (CARD), the European Defence Fund and the Military Planning and Conduct Capability (MPCC) it forms a comprehensive defence package for the EU.
