The Czech Republic has completed the full delivery of 1.8 million artillery shells to Ukraine in 2025, fulfilling a major military assistance commitment made last year, Czech defense officials confirmed. The entire shipment has already reached Ukraine, marking one of Europe’s largest coordinated ammunition support efforts since the outbreak of the war.
According to Czech authorities, more than 80 percent of the ammunition consisted of NATO-standard 155mm shells, with the remainder including 122mm Soviet-caliber rounds and smaller quantities of 105mm artillery ammunition. These calibers are considered critical for Ukraine, which operates a mixed fleet of Western and legacy artillery systems along the front lines.
Before launching the large-scale ammunition transfers to Ukraine, the Czech Republic’s domestic artillery ammunition production capacity was relatively limited. The country’s defense industry traditionally focused on small arms, armored vehicles, radar systems, and selective munitions, rather than the sustained mass production of large-caliber artillery shells required for high-intensity warfare. Prior to 2022, annual Czech output of 155mm, 122mm, and 105mm ammunition was estimated at only tens of thousands of rounds, largely intended for export contracts and national reserves, not continuous battlefield use. This level of production was far below Ukraine’s needs, where artillery consumption has at times reached several thousand shells per day.
Although companies such as STV Group, Czechoslovak Group (CSG), and Explosia possessed technical expertise and partial production capabilities, they lacked the industrial scale, raw-material supply chains, and explosive component availability needed for rapid expansion. Europe-wide shortages of propellants, explosives, and shell casings further constrained output. Acknowledging that domestic manufacturing alone could not meet Ukraine’s urgent requirements, Prague chose to act as a procurement and coordination hub, a decision that directly led to the creation of the Czech initiative, which relies on global sourcing and donor financing rather than immediate large-scale national production.
The Czech Initiative and Its Scale
The deliveries were made under the “Czech initiative,” a flagship program launched by Prague to source artillery ammunition for Ukraine from global markets. Instead of relying solely on domestic production, the initiative pools financial contributions from donor countries and uses the funds to purchase large-caliber shells worldwide, including from third countries and European manufacturers.
Since its launch, the program has become a key pillar of Ukraine’s artillery sustainment. In 2024, approximately 1.5 million shells were supplied to Kyiv under the initiative. For 2025, the target was raised to 1.8 million shells, reflecting the continued intensity of the conflict and Ukraine’s high daily ammunition consumption.
Speaking in early October, Ales Vitek, Director of the Czech Agency for Intergovernmental Defense Cooperation, confirmed that procurement contracts had been secured and deliveries were progressing as planned. He described the initiative as a pragmatic response to shortages in Europe’s defense industry, which has struggled to rapidly scale artillery shell production.
Strategic Importance for Ukraine
Artillery remains a decisive factor in the war, with both sides heavily dependent on sustained firepower. Ukrainian officials have repeatedly warned that ammunition shortages directly affect battlefield performance, including the ability to hold defensive positions and conduct counter-battery fire.
Military analysts note that the dominance of 155mm shells in the Czech shipment is particularly significant, as Ukraine has increasingly transitioned toward NATO-standard artillery systems supplied by Germany, France, Poland, and the United States.
Political Transition in Prague
The completion of the deliveries coincides with a major political transition in the Czech Republic. The outgoing government of Prime Minister Petr Fiala, a strong supporter of Ukraine and the ammunition initiative, resigned earlier this month. In its final statements, Fiala’s cabinet urged the incoming government not to discontinue the program, warning that doing so could damage Czech credibility among allies and weaken Ukraine’s defense effort.
On December 9, Andrej Babiš officially became Prime Minister. Babiš has previously questioned the scale of Czech military assistance to Ukraine, particularly aid financed directly from the state budget.
Uncertain Future of the Program
Babiš has stated that his government plans to reduce military aid to Ukraine and suggested that the Czech ammunition initiative could be halted or revised. According to Reuters, he criticized the scheme as opaque and overpriced, raising concerns about procurement transparency and costs.
However, Babiš has not taken a definitive position on the initiative’s future. The program reportedly enjoys strong support from the Czech president as well as backing from multiple European donor countries, making any abrupt cancellation politically complex.
