As electronic warfare threats evolve, Saab is turning to adaptive artificial intelligence from Finnish firm NestAI to help its systems learn and adjust after deployment.

The partnership will bring NestAI’s technology to selected parts of Saab’s electronic warfare platform.

It aims to address a persistent challenge: defense systems can remain in service for decades, while the threats they face change much faster. 

NestAI said its technology can learn from operational data and adapt to changing conditions. It will be delivered through NestOS, an open, modular operating system designed to work across defense systems and support AI capabilities from different vendors.

“Saab and NestAI are bringing together leading defense and AI expertise to strengthen Nordic and European capability,” Saab Chief Digital Officer Mikael Adelsberg said.

“By combining operational knowledge with advanced artificial intelligence, we are exploring how to lay the foundations for the next generation of secure, sovereign and mission-critical capabilities.”

Saab is known for its sensors, weapons, command-and-control systems, and electronic warfare platforms, while NestAI develops adaptive AI for defense applications.
