In November 2016, Russia had agreed to donate six of its MiG-29s free of charge, if Serbia would pay the repair costs of $50 million for them. At the end of January 2017, Serbian defense minister Zoran Đorđević said that Belarus also agreed to donate eight of its MiG-29s to Serbia on a no-pay basis. In early October 2017, Russia completed the delivery of all the six MiG-29s. The aircraft were transferred to Serbia on board the Antonov An-124 transport aircraft. On 25 February 2019, Belarus formally handed four MiG-29s to the Serbian military during a ceremony held at the 558th Aircraft Repair Plant in Baranavichy. This increased the total number of MiG-29s in the Serbian Air Force to 14. Serbia plans to spend about €180–230 million on modernization of its entire MiG-29 fleet.
