Poland will declassify its military aid to Ukraine from 2022 to 2026, opening years of wartime assistance to public scrutiny.
Defense Minister Władysław Kosiniak-Kamysz announced the decision after consulting Prime Minister Donald Tusk, saying the government would make public all donations provided to Kyiv over the past four years while complying with legal requirements.
The announcement did not specify when the records would be released or what information would be included.
Kosiniak-Kamysz also instructed Poland’s Military Counterintelligence Service to investigate who was responsible for what he described as the deliberate disclosure of state secrets.
“We are operating in conditions of war at our border,” he said. “Every action against Polish national interest endangers the security of Polish women and men.”
Poland-Ukraine Partnerships
Defense cooperation between Poland and Ukraine continued to expand beyond battlefield support into joint industrial development.
In June, PZL Defence and Ukraine’s JSC Ivchenko-Progress signed an agreement to co-develop and manufacture small turbojet engines for aviation and defense applications, while also partnering on engineering education and workforce development.
The growing partnership follows Ukrainian President Volodymyr Zelensky‘s February announcement that the two countries were preparing to jointly produce drones and other weapons.
It also builds on Poland’s December 2025 proposal to exchange its remaining MiG-29 fighter jets for Ukrainian drone technology and Warsaw’s September 2025 decision to launch joint counter-drone training with Ukrainian specialists.
