Zelensky announces use of U.S.-made F-16 fighter jets

Ukrainian pilots have started flying F-16s for operations within the nation, President Volodymyr Zelensky said on Sunday, confirming the long-awaited arrival of the U.S.-made fighter jets more than 29 months since Russia's invasion.

The Ukrainian leader announced the use of F-16s, which Kyiv has long lobbied for, as he met military pilots at an air base flanked by two of the jets with two more flying overhead.

"F-16s are in Ukraine. We did it. I am proud of our guys who are mastering these jets and have already started using them for our country," Zelensky said at a location that authorities asked Reuters not to disclose for security reasons.

The arrival of the jets is a milestone for Ukraine after many months of waiting, though it remains unclear how many are available and how much of an impact they will have in enhancing air defences and on the battlefield.

Russia has been targeting bases that may house them and vowed to shoot them down so they will not impact the war.

Built by Lockheed Martin, the F-16s had been on Ukraine's wish list for a long time because of their destructive power and global availability. They are equipped with a 20mm cannon and can carry bombs, rockets and missiles.

Talking to reporters on the tarmac of an airfield, Zelenskiy said Ukraine still did not have enough pilots trained to use the F-16s or enough of the jets themselves.

"The positive thing is that we are expecting additional F-16s ... many guys are now training," he said.

It was important, he said, that Kyiv's allies found ways to expand training programmes and opportunities for both Ukrainian pilots and engineering teams.

'NEW AVIATION STANDARD'

Ukraine has previously relied on an ageing fleet of Soviet-era warplanes that are outgunned by Russia's more advanced and far more numerous fleet.

Russia has used that edge to conduct regular long-range missile strikes on targets across Ukraine and also to pound Ukrainian front line positions with thousands of guided bombs, supporting its forces that are slowly advancing in the east.

"This is the new stage of development of the air force of Ukraine's armed forces," Zelensky said.

"We did a lot for Ukrainian forces to transition to a new aviation standard, the Western combat aviation," he added, citing hundreds of meetings and unrelenting diplomacy to obtain the F-16s.

"We often heard 'it is impossible' as an answer but we still made our ambition, our defensive need, possible," he said.

It remains unclear what missiles the jets are equipped with. A longer range of missile would allow them to have a greater battlefield impact, military analysts say.

Zelensky said he also hoped to lobby allied neighbouring countries to help intercept Russian missiles being launched at Ukraine through conversations at the Ukraine-NATO Council platform.

"This is another tool, and I want to try it, so that NATO countries can talk to Ukraine about the possibility of a small coalition of neighbouring countries shooting down enemy missiles," he said.

"I think this decision is probably difficult for our partners, they are always afraid of excessive escalation but we are fighting that."
