Poland has nearly quadrupled defence procurement from domestic companies, including joint ventures with central European firms, since 2022 as it builds Europe’s largest land army and seeks greater supply-chain independence. Procurement from those companies reached 30.4 billion zlotys ($8.15 billion) last year, according to Armaments Agency data analysed by Reuters. Poland is expected to spend about €53 billion ($61.45 billion) on core defence this year, up from €44 billion in 2025 and equivalent to around 4.7% of gross domestic product, making it the European Union’s fourth-largest spender behind France, Italy and Germany. Large U.S.-made systems such as Patriot missile batteries, Abrams tanks and F-35 fighter jets remain important, but Warsaw is prioritising regional output of drones, ammunition and other frequently used equipment. The shift is creating opportunities for companies from the Czech Republic, Slovakia, Hungary and elsewhere, while Germany’s Rheinmetall is developing production and maintenance capacity in Poland. The Polish Armed Forces surpassed 220,000 personnel this year, and Warsaw has offered to jointly produce Patriot missiles with Ukraine and the United States.
