DIANA Challenges for 2027: Complete Guide to NATO’s Defence Innovation Accelerator Programme, Funding, Eligibility, and How to Apply

The Defence Innovation Accelerator for the North Atlantic (DIANA) has officially launched its 2027 Challenges, opening a competitive global call for innovators with breakthrough technologies in defence, security, and dual-use applications.

The programme is designed to identify, fund, test, and scale emerging technologies that can address urgent and future-facing security needs across NATO and allied nations. Through its structured Accelerator Programme, DIANA provides innovators with funding, expert support, and access to a world-class test centre network.

At its core, DIANA seeks to bridge the gap between cutting-edge innovation and real-world defence adoption, ensuring that new technologies move quickly from prototype to operational deployment.

What is DIANA? (Defence Innovation Accelerator for the North Atlantic)

DIANA is a NATO-aligned innovation initiative that focuses on identifying and accelerating emerging technologies capable of solving critical defence and security challenges.

DIANA operates through structured challenge calls, where companies submit proposals addressing specific problem statements. Successful applicants become “DIANA Innovators” and enter a multi-stage acceleration pathway.

How the DIANA Programme Works

The DIANA innovation pipeline is structured into four main phases:

1. Innovator Selection

• DIANA launches public challenge calls
• Companies submit technical proposals
• Applications are evaluated based on:
  • Alignment with challenge needs
  • Technical feasibility
  • Novelty and innovation
  • Dual-use potential
  • Commercial viability

Successful applicants are selected as DIANA Innovators and enter a formal framework agreement.

2. Accelerator Programme

Selected innovators enter the DIANA Accelerator Programme, which includes:

• Contractual funding of €100,000
• Technical mentoring and guidance
• Access to DIANA’s test centre network
• Opportunity to refine and validate solutions with end users

This phase focuses on iterating and improving solutions based on real defence requirements.

3. Down-Selection Process

At the end of the accelerator stage:

• A competitive evaluation takes place
• Only selected innovators progress further
• Evaluation criteria include technical maturity, defence relevance, and commercial potential

4. Mission Track

Selected participants may enter the Mission Track, which provides:

• Additional funding of up to €300,000
• Advanced demonstration opportunities
• Investor engagement support
• Pathways to defence adoption contracts

5. Adoption Pathways

All DIANA innovators are supported in identifying pathways for:

• NATO and allied defence adoption
• Commercial scaling opportunities
• Long-term integration into security ecosystems

Dynamic Challenges: Fast-Track Innovation Opportunities

In addition to annual challenge calls, DIANA also runs Dynamic Challenges throughout the year.

These are designed for:

• Urgent defence needs
• Rapid technology deployment
• Highly specific capability gaps

Key features include:

• Rapid iteration and demonstration cycles
• Prototype contracts
• Faster adoption pathways
• Funding support for selected innovators

Example highlighted initiative:

• Decision Superiority for NATO Warfighters Challenge

Important distinction:

• Dynamic Challenge participants typically do not enter the full Accelerator Programme, as these challenges focus on mature solutions ready for rapid deployment.

Funding Opportunities in DIANA Challenges

Participants in the DIANA ecosystem may receive:

• €100,000 initial Accelerator funding
• Up to €300,000 additional Mission Track funding
• Prototype contracts for selected Dynamic Challenge participants
• Access to investors and defence procurement pathways

This makes DIANA one of the most structured defence innovation funding pipelines in Europe and North America.
