About the event


Alliances and Collaboration in Supporting Multi-Domain Electromagnetic Warfare Operations

The complexity of multi-domain operations and the integration required across these domains to control and dominate the electro-magnetic spectrum present significant challenges. Alliances between countries and collaboration across academia, industry and the military are essential elements in achieving these complex goals.

With a history spanning more than 25 years, AOC Europe is a three day conference and exhibition and is the Association's flagship international event connecting 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.  

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.



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
