Finland and Estonia signed a June 30, 2026 letter of intent with Espoo-based NestAI to co-develop military AI for unmanned systems and command and control. The non-binding framework establishes shared research, joint development, training, and technical cooperation without financial commitment, centering on the Finnish Defense Forces AI Center of Excellence and Estonia’s Force Transformation Command. Initial focus areas include adaptive and learning AI, decision support for command and control, and autonomous unmanned systems, with pilot projects identified before wider expansion. The partnership prioritizes open, modular architectures enabling cross-border interoperability without vendor dependence, aiming to build a common expertise pool expandable to other nations and industries while reducing duplicated effort and pooling best practices across the Baltic-Nordic region.
