Ukraine as an Emerging Defense Tech Hub: Legal Challenges, Investment Potential, and the Technology Sector’s  New Role

Unfortunately, Ukraine is already in the fifth year of full-scale war now. This certainly remains an extraordinarily difficult period and a major challenge for everyone in the country — citizens, businesses, institutions, and the Government. Despite the ongoing war, Ukraine has not only preserved its statehood but continues to develop across multiple sectors of the economy, particularly in technology and innovation.

The war has in many ways become a catalyst accelerating the growth of certain segments of the technology industry. Battlefield experience combined with Ukraine’s strong engineering capabilities has given rise to one of the country’s most promising economic sectors — Defense Tech.

This industry is developing rapidly, driven by cutting-edge technologies and real-world operational demands.

Key Advantages of Ukraine’s Defense Tech Sector

Unlike most international defense tech markets, Ukrainian solutions undergo not only laboratory testing or military simulations but real-time battlefield validation. This applies to drone technologies, autonomous systems, battlefield AI, cybersecurity, military analytics, and data management systems. Such practical experience creates unique value for international partners and investors.

According to Brave1 estimates, Ukraine’s Defense Tech sector already encompasses more than 2,500 companies and technology teams. While Ukraine is not yet a global leader in this field, it has every opportunity to become one. There are already examples where military products developed by established global defense manufacturers have demonstrated lower battlefield efficiency in Ukraine than domestically-developed alternatives.

According to a joint study by KSE Institute, Defence Builder, and Brave1, Ukraine’s Defense Tech market reached a value of approximately $6.8 billion in 2025. While overall defense production development remains uneven across the sector, several high-tech segments demonstrated exceptional momentum. Year-over-year UAV production expanded by 137%, electronic warfare systems by 215%, and ground robotic systems by 488%.

While the total volume of investment remains undisclosed for security reasons, the largest share of funding has reportedly been concentrated in AI and software solutions. In addition, more than 700 defense companies received approximately $220 million in grant financing from Brave1 and support through Ukraine’s state-backed “5-7-9%” program.

According to industry estimates, the long-term reconstruction and development potential of Ukraine’s defense sector over the next decade could reach $690 billion.

Independent defense analysts estimate that Ukrainian manufacturers produced nearly 4 million aerial and naval drones throughout 2025. Current industry dynamics suggest that annual output could rise to 6 million units in 2026 even without substantial additional support from foreign partners.

Ukrainian officials, however, believe the country’s production potential is significantly higher. During recent discussions with NATO representatives, Deputy Defense Minister Mstyslav Banik stated that, with sufficient allied investment into domestic manufacturing capacity, Ukraine could eventually scale annual military drone production to as many as 20 million units.

By comparison, China’s yearly drone manufacturing output is often estimated at roughly 2 million units, most of which are designed for civilian rather than military use.

Another major advantage is Ukraine’s strong engineering ecosystem and highly-developed IT expertise. Ukraine has long maintained one of the strongest technology talent pools in Central and Eastern Europe, and wartime conditions have only accelerated innovation cycles. Technologies are developed and adapted significantly faster than in traditional Western defense corporations, driven by near-instant battlefield feedback from military operators.

The sector also benefits from comparatively low development costs relative to the United States and Western Europe, while maintaining a high level of technical competence. In modern wars of attrition, this often gives Ukrainian solutions a significant advantage over more expensive and less adaptive systems.

Ukraine has also been steadily building a more favorable regulatory environment for the technology sector. One of the most notable examples is Diia.City — a special legal and tax framework for IT businesses launched in 2022 that continues to evolve rapidly. The regime provides resident companies with multiple tax incentives, legal protections, and modern corporate structuring tools, significantly improving predictability and attractiveness for international investors and business partners.

This approach was further expanded through the launch of a specialized legal regime for the military-industrial sector — Defense.City. Given its distinct structure, strategic advantages, and growing importance for the Defense Tech sector, the framework deserves a closer look.

Risks & Challenges Facing Defense Tech Development in Ukraine

Despite its enormous potential, Ukraine’s Defense Tech industry continues to face several major risks and structural challenges.

First, wartime risks continue to create uncertainty for international investors, as issues such as physical security, continuity planning, and protection of operations remain key factors in investment decision-making.

Second, the industry still depends heavily on Government funding, international aid programs, and public or private grant financing, making long-term financial stability difficult to attain.

Third, limited production capacity remains a major challenge for the defense industry. Many companies are still early-stage start-ups, making the transition from prototype development to full-scale manufacturing particularly difficult. At the same time, reliance on imported components and external supply chains continues to slow manufacturing growth.

Fourth, factors such as military mobilization, the outflow of specialists abroad, competition from the traditional IT sector, and declining interest in technical manufacturing professions among younger generations continue to deepen the sector’s growing talent shortage.

At the same time, the Cabinet of Ministers of Ukraine has already begun actively addressing this challenge by engaging students through the Brave1 platform, launching experimental defense hackathons, providing grants for young teams and start-ups, and building closer cooperation between universities and key government institutions — including the Ministry of Defense and the Ministry of Digital Transformation.

Another major challenge is the complexity of the regulatory landscape governing defense technologies. Defense Tech businesses today are held back by numerous legal barriers, including export control regulations, sanctions compliance, specialized military procurement requirements, intellectual property ownership issues, cybersecurity obligations, and data protection standards.

Additional restrictions apply to AI-driven products and dual-use technologies, areas already subject to active regulation in both the EU and the US. Meanwhile, this evolving regulatory environment also creates unique strategic opportunities for Ukrainian businesses.

For example, Ukraine is currently expanding its AI-defense ecosystem through initiatives such as Brave1 Dataroom — a secure environment designed for training military AI models using real battlefield data. The project is being developed jointly by Brave1, the Ministry of Defense, the Armed Forces of Ukraine, and U.S. technology company Palantir, with an initial focus on autonomous drone detection and interception systems.

Ukraine is clearly moving toward integration with the Western legal and economic space, meaning that future regulatory models will likely align with EU and U.S. approaches to AI governance, cyber resilience, data protection, export controls, and sanctions compliance. Importantly, much of this regulatory framework in Ukraine is still evolving and, in many areas, remains largely non-binding, allowing companies to launch and scale products within a far more flexible regulatory environment than in most mature Western jurisdictions.

Risk Mitigation: Diia.City, Defense.City, and the Strategic Role of Legal Counsel

As the Defense Tech sector grows rapidly, competitive advantage and investment attractiveness increasingly depend not only on technological expertise but also on effective legal and tax structuring. This is why Ukraine’s specialized legal regimes for the technology sector — Diia.City and Defense.City — are becoming increasingly important.

Diia.City as the Foundation for Technology Business Development

Over the past five years, Diia.City has become one of the most successful regulatory frameworks for Ukraine’s IT industry. Its key advantage lies in creating a predictable and competitive operating environment for technology businesses even under wartime conditions.

For IT and Defense Tech companies, Diia.City offers:

• favorable tax incentives and long-term regulatory stability;
• flexible cooperation models with freelancers and remote teams through gig contracts;
• legally enforceable NDA and non-compete provisions;
• the ability to secure reservation from military mobilization for key employees under specific conditions.

The regime also strengthens intellectual property protection mechanisms and incorporates elements of common law corporate governance and venture investment instruments. Together, these features significantly improve predictability for international investors and venture funds.

For many international partners, Diia.City residency itself already serves as a positive signal regarding a company’s corporate maturity and compliance culture.

Importantly, Diia.City creates an especially effective environment for early-stage technology companies requiring maximum flexibility in team structuring, raising investment, and rapid product scaling. This is particularly important for Defense Tech, where innovation cycles are extremely short, and speed-to-deployment often determines competitiveness.

As of October 2026, Diia.City already unites more than 4,600 resident companies representing nearly 80% of Ukraine’s IT industry. In just the first six months of 2026, Diia.City residents paid UAH 28 billion in taxes — nearly 80%of the total paid during all of 2025 (UAH 34.6 billion).

Defense.City as Specialized Framework for Defense Industry

As noted above, Defense Tech businesses operate within a uniquely complex operational and regulatory environment. To address these issues and stimulate sector growth, Ukraine introduced a separate legal regime — Defense.City.

Defense.City is a state support framework for military-industrial companies involved in the development, manufacturing, or modernization of military products. Its primary goal is to transform the sector into a high-tech, resilient, and globally competitive industrial cluster capable of scaling the production capacity of weapons and military equipment.

In many ways, Defense.City can be described as “Diia.City for the defense sector.” However, its incentives are more heavily focused on manufacturing, export operations, and security.

Among its key advantages are:

• corporate tax exemptions and other tax incentives under certain conditions, enabling companies to allocate more resources to R&D and manufacturing;
• simplified export procedures for military products and international technology transfers — a critical driver of growth for Defense Tech companies seeking to scale globally;
• accelerated customs procedures, administrative processes, and reporting requirements;
• enhanced business protection mechanisms, including limited public disclosure of sensitive corporate information;
• state support for production relocation and infrastructure protection;
• access to Government financing and integration into national defense programs.

Taken together, these features demonstrate that Defense.City is designed less for early-stage start-ups and more for established manufacturers and developers seeking to scale through integration into the state defense ecosystem, exports, and international partnerships.

Should Diia.City Residents Consider a Transition to Defense.City?

In practice, this question should not be viewed as a choice between two mutually exclusive regimes. On the contrary, the most effective model may lie in combining the advantages of both frameworks.

Diia.City already provides flexible corporate structuring, tax efficiency, investment-friendly mechanisms, and flexible workforce models — making it highly suitable for start-ups and technology developers. Defense.City, meanwhile, optimizes industrial production, capital investment, export operations, and defense contracting.

Ukraine is effectively building a two-level regulatory architecture: Diia.City as a general technology infrastructure layer and Defense.City as a specialized Defense Tech layer. Together, these frameworks create a globally competitive environment for international growth and investment.

The Strategic Role of Legal Counsel in Navigating Both Regimes

For Defense Tech businesses, selecting the right legal regime is no longer a matter of choosing a formal framework. An improperly structured model may create significant legal, tax, operational, and investment risks.

This makes comprehensive legal analysis essential. Companies must carefully evaluate their business model, growth strategy, operational goals, export plans, intellectual property structure, and investment roadmap together with legal advisors experienced in both technology and defense-sector regulation before deciding which legal regime — Diia.City, Defense.City, or a combination of both — best fits their business.

In rapidly evolving sectors such as Defense Tech, AI, cybersecurity, and dual-use technologies, the role of legal counsel extends far beyond risk management. Legal advisors increasingly act as strategic partners, helping companies shape scalable corporate structures that support long-term international expansion and investment growth.

Conclusion

Ukraine has already developed a rapidly growing technology ecosystem at the intersection of IT, Defense Tech, AI, and cybersecurity.

Defense Tech founders are working actively to transform Ukraine’s defense industry into a global innovation hub. This will inevitably drive further growth in innovation, technology development, R&D, international partnerships, and the continued evolution of regulatory frameworks.

That is why close cooperation between Ukrainian technology businesses, the state, and international institutions is becoming increasingly important. This cooperation is already taking shape through specialized legal regimes, dedicated platforms, and industry-focused organizations.
