SEATOM to Make Waves in Maritime Nuclear Propulsion

Finland-based startup SEATOM has recently made headlines following its selection for the NATO Defense Innovation Accelerator for the North Atlantic (DIANA) Challenge Program Cohort 2026. This initiative underscores SEATOM's innovative approach in advancing nuclear propulsion solutions tailored for both civilian and defense applications, particularly in extreme maritime environments like the Arctic.

A Groundbreaking Selection

Announced on December 11, 2025, SEATOM's selection marks a significant milestone. The company aims to tackle pressing defense and security challenges. Their modular nuclear reactor system has been recognized for its potential to operate efficiently in harsh conditions, catering to the growing need for reliable, sustainable energy sources in the maritime sector. As international regulations around nuclear technology evolve, public sentiment is increasingly favorable towards nuclear maritime solutions.

Strategic Involvement with NATO

Over the next six months, SEATOM will engage with the program's DualTech Accelerator in Turin, Italy, tapping into a broad network that includes experts, mentors, and testing facilities. This collaboration will expose SEATOM to advanced testing infrastructures and provide direct engagement with NATO end-users, allowing for rapid feedback and validation of their technology.

Co-founder Roope Marttila notes, “This is an opportune moment for nuclear energy, especially within maritime applications. As we navigate industry and public discourse, our commitment to developing nuclear propulsion systems position us favorably.” This confidence is reflected in their initial funding of €100,000, with the possibility of further financial support for testing and operational validation activities.

Building Technological Readiness

The NATO DIANA Challenge Program is designed to bridge the gap for emerging technology innovators looking to make an impact in the defense and security sectors across NATO’s 32 member countries. SEATOM's involvement in this program will not only enhance its technological readiness but will also solidify its offerings in dual-use defense capabilities. Participants in the cohort will be able to test their solutions under real operational scenarios alongside allied forces, accelerating the transition from concept to deployment.

Joining Forces with Innovators

SEATOM joins a distinguished group of innovative enterprises working on cutting-edge solutions essential for the defense and security of the West. The program is set to kick off on January 19, 2026, culminating in a demonstration day scheduled for June 2026 in Paris.

As NATO continues to explore advanced technologies in defense, SEATOM's advancements provide a glimpse into the future of maritime operations powered by nuclear energy. The company's commitment to sustainable solutions reflects a growing recognition of nuclear propulsion's role in modern maritime safety and efficiency.
