About the programme
NATO's dual-use accelerator runs annual challenge-based calls and puts selected companies through a six-month programme with non-dilutive funding, mentoring and access to a network of more than 200 test centres across Europe and North America. The 2027-cohort call (closed July 2026) covered six challenge areas: human survivability, multidomain autonomy of uncrewed systems, multidomain sensing and data processing for ISR, operational resilience in contested environments, responsive logistics, and scalable air-defence countermeasures. Since 2026 DIANA also operates the Rapid Adoption Service, awarding R&D and prototype contracts to innovators on behalf of individual Allies; the first such contract was signed in April 2026.
