One of the consequences of the ongoing war in Ukraine is simply a crucial cut-off from the sources of spare parts and key components for the Posovian progenitors. Poland has the largest fleet of specified machines in the "Mi" family, with more than 60 assault, transport and seaplanes. As a consequence of many years of negligence, only now does MON begin the exchange process, pursued by both the needs of the armed forces and exhausted resurs and melting spare parts stores. Is ad hoc buying the best way to improvement the fleet?
