The deal, signed earlier this year by the outgoing administration, marks the country’s largest-ever military procurement and aims to modernize its air force and align with NATO standards. The fifth-generation aircraft are set to replace Czechia’s leased Gripen fighters, with first deliveries starting in 2031 and full deployment by 2035. Defense officials say the move ensures long-term security amid Russia’s ongoing war in Ukraine, despite domestic debate over budget priorities.
