Ukraine finally deploying F-16 fighter jets, says Zelenskiy

Ukrainian pilots have started flying F-16s for operations within the nation, President Volodymyr Zelenskiy said on Sunday, confirming the long-awaited arrival of the US-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," Zelenskiy 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
