Growing South Australian company Codan today announced it would buy the intellectual property of a United States-based communications business for $21 million.

Called Adaptive Dynamics, the company specialises in anti-jamming and interference mitigation technologies for mission-critical communications applicable to defence and national security systems.

According to a Codan press release, the new subsidiary would complement the Adelaide-based company’s technical capabilities in the US and would strengthen its positioning for next-generation defence programs.

This was particularly important for programs requiring resilient and secure communications, electronic warfare resilience and AI-enabled integration, the release said.

“This capability is increasingly critical for DTC’s customers reflecting real-world operational demands and evolving battlefield requirements.”
