Denmark is a consistent and principled ally of Ukraine in countering Russian aggression. As of the end of 2025, the country ranks among the world's top five nations in terms of military support to Ukraine. Since the full-scale war began, Denmark has delivered 29 packages of military aid, demonstrating consistency and strategic support for Ukrainian resistance. Total support exceeds 3% of Denmark's GDP – the highest in the world as a share of the economy.

The symbol of Danish military support has been the transfer of F-16 fighters – the first Western combat aviation for Ukraine, which dramatically strengthened Ukrainian air defense capabilities. In addition, comprehensive training of Ukrainian pilots and technical personnel is underway. Denmark has deployed military instructors to the United Kingdom to train Ukrainian defenders under Operation Interflex, and also conducts training courses for Ukrainian military personnel on its territory.

Denmark has transferred armored vehicles to Ukraine – Leopard tanks, T-72s, infantry fighting vehicles, and participated in creating a technical maintenance base. Artillery support included the transfer of CAESAR howitzers. Denmark transferred its entire available artillery inventory and financed the procurement of additional howitzers. A unique project has been the production of Bohdana self-propelled howitzers directly in Ukraine. Denmark systematically assists Ukraine with air defense systems and ammunition.

Danish assistance covers a wide range of weapons and military equipment, including armored vehicles, drones, air defense systems, and other equipment. A distinctive feature of Danish support is not only material and technical provision, but also comprehensive training of Ukrainian military personnel.

Denmark participates in eight international coalitions supporting Ukraine, including artillery, tank, aviation, IT coalition, air defense coalitions, drones, demining, and naval capabilities. This enables comprehensive and systematic support for Ukraine's defense capability.

In March 2023, the Danish government established a special National Ukraine Support Fund, which provides long-term military, humanitarian, and economic assistance. The country was the first to implement a unique mechanism for direct procurement of weapons from Ukrainian manufacturers (the "Danish model"). 

A defining event of 2025 was the evolution of Danish support from a donor model to strategic defense-industrial partnership. A memorandum was signed on establishing production facilities by Ukrainian companies on Danish territory.

An important area of support is training Ukrainian military personnel to NATO standards, particularly at Danish military airbases and training centers. Denmark also promotes cyber resilience of Ukrainian defense structures and supports modernization of the domestic defense industry.

On February 23, 2024, a Security Cooperation Agreement was concluded, providing for a ten-year strategy of supporting Ukraine, including development of the defense industry, intelligence cooperation, and promoting accountability for crimes of aggression.

Danish military assistance is viewed not only as support for Ukraine, but as a key element of ensuring European security, deterring Russian aggression, and defending the international legal order.
