Since the beginning of the Russian invasion of Ukraine, Poland has been among the most active countries in supporting its eastern neighbour to halt the advance of Russian forces and to conduct its counteroffensive. This decision was consistent with Polish strategic objectives, allowing Poland to launch its modernisation project and expand its military capabilities. Although Poland’s strategic rationales vary depending on the political stance of its elites (Pawłuszko, 2022), there are three common denominators: the intent to deter Russia, the need to secure US support, and the ambition to become the Central-Eastern European region’s leading power.  Poland considers strengthening its armed forces as essential for achieving these goals. In fact, Warsaw aspires to build the most potent European land force by the beginning of 2026 (Tilles, 2023). While this objective is ambitious, the Russian invasion has catalysed the modernisation of the Polish military and its arms industry (Cucino & Scarazzato, 2023).This paper will address Poland’s recent strategic investments, aimed at developing multiple components of its armed forces, including land, air, sea, drone, and anti-missile forces, and analyse the potential challenges that such a rapid upgrade and amplification of its military capabilities entail.
