NestAI and Nokia unveil AI defense capabilities Europe wants to control

NestAI Emerges as Europe's Answer to Sovereign AI Defense

A Helsinki AI lab barely a year old is positioning itself at the center of Europe's push for military technology independence. NestAI, founded in 2025, now employs close to 200 engineers and scientists after securing €100 million from Nokia and Tesi, Finland's state investment company, in November 1

. The investment makes it one of the better-capitalized physical-AI labs on the continent, arriving at a moment when European defense forces are actively seeking alternatives to foreign-controlled systems.

The company's core product, NestOS, functions as an AI-driven operating layer for unmanned military vehicles and command-and-control systems 1

. Built on open, modular architectures, the system is designed to continue learning after deployment rather than freezing at delivery. This approach addresses a critical gap: European military autonomy in an era when running critical infrastructure on external terms has become increasingly uncomfortable.

Nokia Defense Partnership Delivers First Operational Capabilities

On July 9, Nokia Defense and NestAI unveiled their first operational output following the November investment. The partnership has created three integrated capabilities designed for what the industry calls denied environments—places where satellite navigation is jammed, bandwidth collapses, and autonomous systems must continue functioning 2

The first capability combines Nokia's deployable 5G networks with NestOS to help European defense forces maintain AI-based command and control while supporting autonomous systems 2

. The second integrates Nokia's radio-network planning models into NestOS mission-planning tools, enabling forces to assess and adapt connectivity during operations 3

. The third merges Nokia's Integrated Sensing and Communications early-detection capability with NestAI's multi-sensor tracking to provide wide-area situational awareness in contested environments 2

"Defense is moving quickly to adopt AI-enabled defense capabilities, from mission planning to unmanned operations. But AI only works in the field when it has secure, resilient connectivity behind it," said Mikko Hautala, Chief Geopolitical & Government Relations Officer and Chairman, Nokia Defense 2

. These technologies are built to NATO operational requirements using European-developed systems 2

Finland and Estonia Sign Framework for AI Support for Defense Operations

On June 30, Finland's Ministry of Defence, the Estonian Defence Forces, and NestAI signed a letter of intent that contains no financial commitments but establishes a framework for knowledge sharing, joint development, training, and technical cooperation 1

. The agreement ties Finland's AI Centre of Excellence to Estonia's Force Transformation Command, with NestAI as the industrial partner.

The first work strands focus on adaptive and learning AI, decision support for command and control, and autonomous and unmanned systems 1

1

. Major General Sami Nurmi, deputy chief of staff for strategy at Defence Command Finland, placed the letter inside the Finnish Defence Forces' data and AI strategy launched last year, stating the aim is to bring further nations into the arrangement 1

Why Sovereign AI Systems Matter for European Defense Forces

"European defense forces need AI systems that work together across national boundaries and continue to learn after deployment," said Peter Sarlin, NestAI's executive chairman. Capability evolution, he added, should stay "in the hands of the nations who operate the systems" 1

.

This sovereignty clause drives the entire strategy. Open and modular design is not merely an engineering preference but a procurement doctrine: no single vendor controls the roadmap, and each country maintains sovereign control of its own data 1

1

. Finland shares 1,340 kilometers of border with Russia, and Estonia sits across the Gulf, geography that concentrates minds about who writes the software and where the weights are stored 1

.

NestAI works with the Finnish Defence Forces and lists Patria and Bittium among its industry partners 1

. While Munich's Helsing, valued at $18 billion, has built an alliance with Mistral on military AI defense, NestAI offers proximity and direct collaboration with governments seeking AI-driven operational capabilities they can control 1
