The selection reflects SEATOM’s focus on dual-use technologies that address defence and security needs in demanding settings such as the Arctic. Over the next six months, the company will take part in DIANA’s Core Programme in cooperation with the DualTech Accelerator in Turin.
SEATOM will work with DIANA’s network of experts, mentors, and test centres across the Alliance, gaining access to testing infrastructure and defence market guidance. It will also engage directly with NATO end-users through the programme.
“This is the right time for nuclear, as national and international regulations are being reformed and public perception now favors maritime nuclear more than any other viable option out there”, said Roope Marttila, cofounder & co-CEO. As part of the programme, SEATOM will receive an initial €100,000 in contractual funding with the possibility of further support for testing, evaluation, validation and verification.
The company will have opportunities to join operational experiments and exercises with Allied forces. DIANA’s Challenge Programme serves as an entry point for emerging technology firms seeking to operate in the defence and security sector across NATO’s 32 nations.
Through the programme, SEATOM expects to strengthen its technological readiness and its dual-use offerings. The 2026 cohort includes companies developing technologies seen as critical to Western defence, with activities beginning on 19 January 2026 and culminating in an International Demo Day in Paris in June 2026.
