The highly-anticipated first batch of F-16 fighter jets finally arrived in Ukraine after more than a year of intense negotiations and rigorous pilot training to rebuild Kyiv’s depleted air force.

The delivery, confirmed by both US and Lithuanian officials last Wednesday (July 31), marks a significant boost to Ukraine’s aerial capabilities.

President Volodymyr Zelensky also confirmed on Sunday, August 4, that the F-16s had arrived and that Ukrainian pilots were already using them.

“I am proud of all our guys who master these planes and have already started using them for our state,” Zelensky wrote in a social media post, along with the photos of the fighter jets in an undisclosed location in Ukraine.

While Zelensky spoke at Ukraine’s Air Force Day celebration, the two F-16s can be seen in the background. Both jets bore the country’s trident insignia on their tails and were covered in camouflage netting.
