The long-awaited arrival of U.S.-made F-16s have allegedly landed in Ukraine, officials said Wednesday, a move that will help Kyiv revive its air capabilities in its war against Russia. 

Ukrainian President Volodymyr Zelenskyy has repeatedly emphasized his country’s need for superior air support and aircraft since Russia invaded more than two years ago. 

Despite international willingness to provide warplanes to Kyiv, the U.S. previously refused its F-16 technology over concerns it could escalate the war beyond Ukraine’s borders – a similar position it took with other wartime capabilities like long-range ATACMS missile systems and Abrams M1 tanks before Washington again capitulated. 

Lithuanian Foreign Minister Gabrielius Landsbergis, an ardent supporter of Kyiv, took to X to confirm the delivery and said, ‘F-16s in Ukraine. Another impossible thing turned out to be totally possible.’

Despite multiple reports citing U.S. intelligence officials, neither the Pentagon nor Ukrainian defense officials have officially confirmed that the sorely needed warplanes have been delivered.

Kyiv’s push to keep the F-16 arrival a secret is not a surprising decision given the security challenges the planes will prove for the war-torn state. 

Ukrainian pilots have been training on F-16 systems in the U.S. and in Europe as they look to roll out a new defense with the modern warplanes.

However, Ukraine will also need to secure the planes while they remain on the ground as they are expected to be a top target for Russian forces looking to destroy the F-16s. 

When asked about the arrival of the F-16s by reporters Wednesday, White House National Security Communications Advisor John Kirby said, ‘I’m certainly not going to talk about weapons capabilities.’ 

‘We have said, and said at the NATO summit, that the process of providing F-16s to Ukraine continues to move forward,’ he added. ‘We said that they will be operational by the end of the summer. We have no reason to doubt that.’

Zelenskyy has long emphasized the important role F-16s would serve in bolstering Ukraine’s air defenses as Russia continues to pummel the country with drone and missile strikes. 

‘Last night alone, almost 90 ‘Shahed’ drones were shot down,’ Zelenskyy said in a Wednesday address to the nation.  ‘This is a serious result. I thank everyone for their precision: our mobile fire groups, fighter aircraft crews, anti-aircraft gunners, electronic warfare specialists — everyone.’

‘You have done an excellent job in the skies across many of our regions,’ he added. ‘It is also crucial to increase Ukraine’s skies defense capabilities.’
