Ukraine has received more than 50,000 rounds of 20-mm ammunition from Denmark for the onboard cannons of its F-16 fighter jets, with Ukrainian pilots already using the rounds to intercept Russian jet-powered Geran attack drones, Ukraine’s Defense Ministry said.

The accelerated delivery addresses a key need in Ukraine’s air defense as Russia increasingly deploys faster jet-powered drones that challenge conventional interceptors. Ukraine has also relied on F-16 cannons when stocks of air-to-air missiles are limited, making ammunition supplies important to keeping the aircraft effective against incoming aerial threats.

Denmark responds to ammunition request

The Defense Ministry thanked Denmark for responding quickly to Ukraine’s request for additional ammunition, saying the delivery directly strengthens the country’s air defenses and helps protect civilians from Russian aerial attacks.

The delivery follows a broader effort by Ukraine’s European partners to replenish F-16 cannon ammunition. On October 2, it was reported that Spain, Belgium, and Poland were also sending 20-mm rounds for Ukrainian F-16s to counter Russia’s jet-powered drones.

Belgium is also expanding its support for Ukraine’s F-16 fleet. On 16 October, Belgian Prime Minister Bart De Wever pledged to deliver 10 F-16s by the end of 2026, up from three previously planned, and discussed supplying additional ammunition, including 20-mm rounds produced by Belgian defense company FN Herstal.

Jet-powered drones pose a growing challenge

Russia’s faster attack drones are harder to intercept than older, propeller-driven Shahed-type models. Their speed gives air defenders less time to respond and makes them more difficult for many interceptor drones and conventional short-range weapons to catch.

Ukraine’s air-to-air missile shortages have also increased the importance of F-16 cannon ammunition. Ukrainian pilots have sometimes relied on their aircraft’s built-in 20-mm cannon when air-to-air missiles are scarce.

The threat from jet-powered drones is growing. Ukrainian President Volodymyr Zelenskyy said in late September that Ukraine was intercepting about 55% of Russia’s jet-powered drones, compared with more than 90% of older models.

Denmark’s ammunition delivery gives Ukrainian F-16 pilots more rounds to engage these faster targets, as Ukraine works to strengthen its defenses against Russia’s expanding drone campaign.

Ukraine has received undisclosed assistance from Poland as it struggles to defend against increasingly intense Russian drone and missile attacks, President Volodymyr Zelenskyy hinted during a meeting with Polish Prime Minister Donald Tusk in Brussels on 15 October, Radio Svoboda reported.

Ukraine’s air defense needs are greater than at any point since 2022, as intensified Russian drone and missile attacks strain existing systems and expose shortages of interceptor missiles. With US support increasingly uncertain amid tensions between Kyiv and Washington, European military aid is becoming more critical to Ukraine’s ability to defend its cities and infrastructure.

Zelenskyy thanked Warsaw for its support, suggesting that some assistance had to remain confidential. He also specifically mentioned 20 mm ammunition, which Ukraine needs to defend its cities against Russian attacks.

“Sometimes this has to stay between the two of us,” Zelenskyy said, thanking Tusk for the aid.

European support increasingly important amid US rift

Ukraine is facing mounting pressure on its air defenses as Russia increases the scale of its aerial attacks. Ukrainian forces are also struggling with shortages of interceptor missiles, particularly Patriot missiles needed to counter Russian ballistic strikes, leaving the country vulnerable to further attacks.

The need for additional support comes amid growing uncertainty over US assistance under President Donald Trump. Washington has taken steps that have strained ties with Kyiv, including easing some restrictions on Russian fuel and pressing for an energy ceasefire that Ukraine says Russia has continued to violate. 

Recent disruptions to US-linked intelligence and satellite support have also raised concerns about Ukraine's ability to detect and counter Russian attacks.

As uncertainty over Washington's role grows, European military assistance is becoming increasingly important for Ukraine's defense.

Tusk reaffirmed Poland's commitment to supporting Ukraine, saying Kyiv could count on Poland and the European Union. He also opposed easing EU sanctions against Russia, arguing that Europe should not take steps that help Moscow finance its war.

The meeting also came amid strained relations between Kyiv and Warsaw over historical disputes. However, Poland's government has maintained that these disagreements should not undermine military support for Ukraine, whose ability to resist Russian aggression is closely tied to Poland's own security.
