Denmark has delivered 50,000 rounds of 20 mm ammunition for the autocannons on Ukraine's F-16 fighter jets, Ukraine's Defense Ministry said on Oct. 23. The U.S.-made jets, first delivered to Ukraine in 2024, have become a key part of the country's defenses against Russian attacks on its rear areas, particularly jet-powered drones.
"Ukrainian pilots are already using them to intercept jet-powered attack drones," the ministry said on social media. "We are grateful to Denmark for its quick and efficient response to our request for additional ammunition."
F-16 fighter jets are equipped with 20 mm M61 Vulcan rotary cannons designed for close-range engagements, in addition to mounting points for various air-to-air and air-to-ground missiles. While missiles are often used to shoot down Russian cruise missiles during mass attacks, the cheaper autocannon ammunition is frequently used against Russian jet-powered drones, which are too fast for most Ukrainian interceptor drones to intercept.
On Sept. 30, Bloomberg reported that Kyiv was seeking to procure additional 20 mm rounds for its F-16s, with sources saying an average of 150 rounds was required per interception. President Volodymyr Zelensky said on Oct. 5 that Ukraine was "scouring munitions for F-16s virtually all over the world." Zelensky also praised the jets as one of the most effective means of countering jet-powered drones.
Denmark, the Netherlands, Belgium, and Norway have collectively supplied Ukraine with around 50 F-16 fighter jets. Intensive use in defending Ukrainian airspace means the jets require frequent maintenance, which can currently be carried out only by Kyiv's partners.
