PESCO, or the Permanent Structured Cooperation, is a framework established by the European Union to enhance defense cooperation among its member states. Launched in 2017, PESCO aims to foster collaboration in military capabilities, improve defense readiness, and promote joint projects. Member countries voluntarily commit to deeper defense integration, which includes sharing resources and expertise. PESCO also encourages the development of new military technologies and capabilities, ensuring that the EU can respond effectively to security challenges while strengthening its strategic autonomy.
