Poland recently secretly transferred about ten Mi-24 helicopters to Ukraine.
This is reported by the Wall Street Journal, citing their sources.
According to the publication, no public announcement was made regarding the helicopter handover from Poland.
However, President Andrzej Duda said in May that this was "almost all the helicopters" Warsaw had had at its disposal, and was ready to continue transferring the rest systematically.
At the same time, the journalists write, Ukraine's air fleet "remains small in comparison to the russian one." In addition, Ukrainian aircraft have "less sophisticated guidance and protection systems."
Background. It was also reported recently that Slovakia would supply Ukraine with additional 16 Zuzana 2 self-propelled artillery units. The contract between the countries has already been signed.
