F-16s in service with Ukraine's armed forces are in need of repair, making them difficult to use, Zelenskiy said.
According to him, the planes transferred to Ukraine are not new, and they require constant repairs, so there are restrictions on their use.
At the same time, Ukraine, according to him, needs two and a half times more planes in the sky.
"We are also asking for F-16s. There are usage restrictions because the planes are not new. Today we need two and a half times more planes in the sky at the same time than the number we use. I mean, we have all that on paper, but they're constantly under repair, because the F-16s are not young. We need to work on this issue with the Americans as well - we are doing it," Zelensky said.
Also, according to Zelensky, there is not enough ammunition for aircraft guns, while the F-16 is one of the main tools in the fight against casualties.
