Bulgaria's interest in buying Poland's retiring MiG-29s has pushed Warsaw and Kyiv closer to finalizing their long-stalled swap, Polish officials say.
Poland and Ukraine are in the final stage of negotiating a deal to transfer Poland's aging MiG-29 fighter jets to Ukraine in exchange for drones and Ukrainian drone-warfare know-how, with the jets potentially shipping within weeks, Polish outlet Wirtualna Polska reported, citing sources in the Polish Armed Forces and Defense Ministry. The report follows months of on-and-off talks that Poland's own officials have repeatedly declared both close to done and dead.
Polish Deputy Defense Minister Cezary Tomczyk said on Polsat News that Bulgaria's competing interest in the jets has "livened up" Warsaw's discussions with Kyiv. Bulgaria has told Poland that if Ukraine will not commit, Sofia would buy the jets itself, Tomczyk said.
"I hope it will be soon," Tomczyk said when asked when Poland intends to sign the agreement with Ukraine. He said Poland has laid out the technologies and know-how it wants from Ukraine in return, calling the exchange in both countries' interest. "Today I cannot say with 100% certainty that this matter will be finalized, but we hope so."
According to Wirtualna Polska, the deal covers Soviet-era jets Poland's air force is retiring as it phases in Western aircraft, in exchange for a large batch of Ukrainian drones of various types and the transfer of Ukrainian combat know-how. The outlet reports Poland wants data on strike-drone communications links, control principles, footage of strikes on targets, and physical samples of the hardware itself.
Poland's Defense Ministry has said the process picked up pace after Rustem Umerov took over as head of Ukraine's Foreign Intelligence Service, with President Volodymyr Zelenskyy tasking him with negotiating drone agreements. A source involved in the talks told Wirtualna Polska that Ukrainian drone maker Fire Point has offered to supply Poland with 1,500 long-range drones, plus a matching batch if war breaks out — an offer the source said Poland regards cautiously, since a company citing force majeure in wartime could leave Warsaw without the hardware it was promised.
A deal that has collapsed and revived for a year
Poland and Ukraine signed a bilateral security agreement in July 2024 that raised the prospect of transferring a squadron of at least 14 Polish MiG-29s. By early 2026, Warsaw had narrowed the offer to six to eight jets. In June, Poland froze the transfer, with Deputy Defense Minister Tomczyk citing Ukraine's refusal to share its drone and counter-drone technology. Talks restarted in July after Kyiv sent Warsaw a letter with concrete proposals, and by 31 July, Poland said Ukraine had returned with a specific list of drones it would hand over — a proposal Poland's ministry was still reviewing.
Poland's ambassador to Ukraine, Vasyl Bodnar, told Ukrainska Pravda's Yevropeiska Pravda that dialogue continues but that several obstacles still stand in the way of the transfer.
Why this matters
The MiG-29 remains a core part of Ukraine's air force even as it shifts to F-16s, Mirages, and incoming Gripens — Ukrainian pilots already fly the Soviet-era jets and have adapted them to carry Western precision weapons, so a new batch could enter service without the delays a Western aircraft transition requires. Poland's own hesitation reflects the same trade-off every one of its allies faces: what it gives up in hardware, it wants back in the operational knowledge Ukraine has built fighting Russia's drone war for four years — knowledge with no equivalent on any NATO training ground.
