Poland's authorities have no intention to hand over all its MiG-29 jet fighters to Ukraine at once, Polish Deputy Foreign Minister Pawel Jablonski said on RMF radio.
Jablonski added that the Polish Defense Ministry does not disclose further details of the handover process.
"I believe we will not give away everything. Definitely not in one batch," he said.
According to Jablonski, the handover process is classified.
"I am unable to say precisely how it will go. The Defense Ministry has preferred to keep this business classified so far," he said, adding that the information about the handover of the jets will be published soon.
Currently, Poland has 28 MiG-29s, which are located at Malbork Air Base.
On March 16, Polish President Andrzej Duda announced that Ukraine would soon receive its first four MiG-29s from Poland.
According to Duda, the remaining planes are under maintenance and will be delivered as soon as they are ready.
