Permanent Structured Cooperation (PESCO)
Permanent Structured Cooperation (PESCO) is a treaty-based EU framework under Article 42(6) and Protocol 10 of the Treaty on European Union. Through PESCO, willing member states make binding commitments on defense capability development and run multinational projects together. PESCO operationalises EU defense cooperation in a way that the EDF then partially funds.
Etymology / origin
Activated in December 2017 with 25 of the then-28 EU member states (Denmark joined later in 2023 after revoking its defense opt-out; Malta and the UK abstained for different reasons). PESCO sits in the Lisbon Treaty's provisions on Common Security and Defence Policy.
Where you encounter this term
PESCO currently runs over 60 collaborative projects across capability areas such as military mobility, cyber, maritime, and air systems. Project membership and lead-nation assignments are public; supplier participation usually flows through the lead nation's defense industrial base. PESCO projects frequently align with EDF funding calls, providing the consortium structure that EDF requires.
Example — from the WULFRN database
PESCO project lineage often underpins multinational acquisition pipelines that later show up as joint awards in TED or NSPA notices. WULFRN's 22,351 defense records include suppliers active across multiple PESCO-driven capability lanes.

Frequently asked questions
What is PESCO in EU defense?
PESCO (Permanent Structured Cooperation) is a treaty-based EU framework under Article 42(6) of the Treaty on European Union. Member states that join PESCO make binding commitments on defense capability development and run collaborative projects together, currently over 60 projects across capability areas.
Which EU countries participate in PESCO?
All 27 EU member states except Malta currently participate in PESCO. Denmark joined in 2023 after revoking its defense opt-out. PESCO does not include non-EU NATO Allies like Norway, the UK, or Türkiye, though some PESCO projects allow third-party participation by invitation.
How does PESCO relate to NATO?
PESCO is an EU instrument and operates independently of NATO command. Many PESCO projects align with NATO Defence Planning Process priorities by design, and most PESCO participants are also NATO Allies, so capability output is generally complementary. PESCO does not replace NATO planning or commitments.
