The EU Council Decision establishing the EDA foresees three types of cooperative instruments:
- Ad Hoc Category B Projects or Programmes (article 20 of the Council Decision)
- Ad Hoc Category A Projects or Programmes (article 19)
- Studies funded from EDA Operational Budget (article 13).
Ad Hoc Category A and B R&T Projects and Programmes are the main instruments of collaboration in the EDA Research & Technology Directorate.
They are prepared and monitored in specific Capability Technology groups ("CapTechs").
