About the event


Achieving Multi-Domain Integration

Association of Old Crows (AOC) is an organisation for individuals who have common interests in Electronic Warfare (EW), Electromagnetic Spectrum Management Operations, Cyber Electromagnetic Activities (CEMA), Information Operations (IO), and other information-related capabilities.

With a history spanning more than 25 years, AOC Europe is the association's flagship international event.

Across three days, the show connects organisations and individuals from government, defence, industry, and academia to promote the exchange of ideas and information and review the latest advances in these fields.


Highlights from AOC Europe 2023

Why attend?

Meet world-leading experts to discuss their understanding of the issues, technology and capabilities that underpin evolving electronic warfare abilities, both nationally and in collective defence. Alongside a technical conference programme, the event features an exhibition area for specialist suppliers to showcase their technologies, products and services.

“The event was very good and offered great networking possibilities both with peers and the industry. Additionally, it was nice to hear about EW/CEMA developments first-hand.”

Paul Hoen - Staff officer CEMA, MOD, Royal Netherlands Army
