 Poland seeks Berlin's consent to transfer MiG-29 jets to Ukraine. Poland has sent an official request to Berlin to transfer MiG-29 fighters from the former German Democratic Republic to Ukraine. DPA news agency announced it, citing sources in the authorities. These fighter jets were in service in the GDR during the Cold War and were inherited by the Bundeswehr and in 2002 Germany sold them to Poland. At that time, 23 aircraft were sold to Warsaw. At the end of March, Polish presidential advisor Jacek Siwera said the Polish Air Force still had about a dozen of them in service. Since virtually all German arms sales contracts stipulate that further transfer or resale requires Berlin's approval, Poland must obtain German consent to transfer the fighter jets to Ukraine. It is not specified how many aircraft the request refers to. In early April, Polish President Andrzej Duda said that Warsaw had handed over eight MiG-29 jets to Ukraine and was preparing six more for delivery. He also added that Poland still has MiGs that have been modernized and are now adapted to NATO standards, primarily in terms of communications and issues related to the ability to perform, for example, an air patrol mission within NATO. Besides, Slovak government decided to transfer 13 MiG-29 fighters to Ukraine. The first four of them have already been sent to Ukraine.
