Poland Becomes Europe's Largest Defence Spender as Military Modernisation Accelerates

Warsaw's defence budget hits 4% of GDP as Poland rapidly deploys new tanks, aircraft, and missile systems from South Korea and the United States.

Poland's Military Revolution: From Soviet Relics to Cutting-Edge Arsenal

Poland has emerged as Europe's largest defence spender in absolute terms among non-nuclear EU member states, with its 2026 defence budget reaching approximately 4 percent of GDP — a level that exceeds even the United States in terms of proportional commitment and that reflects Warsaw's determination to never again be vulnerable to Russian aggression. The transformation of the Polish armed forces from a largely Soviet-legacy force to a modern, NATO-interoperable military is proceeding at a pace that has impressed allies and surprised sceptics who doubted Poland's institutional capacity to absorb such rapid change.

The Polish military modernisation programme relies heavily on purchases from South Korea, which has emerged as a preferred partner for Warsaw due to a combination of competitive pricing, rapid delivery timelines, and willingness to include technology transfer provisions. Poland has contracted for hundreds of K2 Black Panther main battle tanks, FA-50 light combat aircraft, K9 Thunder self-propelled howitzers, and multiple rocket launcher systems, with deliveries proceeding ahead of schedule.

American systems form the other pillar of Polish rearmament. Poland operates several batteries of Patriot air defence missiles and has contracted for additional units, and discussions are ongoing about the potential deployment of US intermediate-range missile systems to Polish territory — a development that Russia has warned would cross a red line. F-35A fighter jets ordered from Lockheed Martin are scheduled to begin arriving in 2024 and deliveries continue through 2026 and beyond.

The ICEYE synthetic aperture radar satellite contract, signed in May 2025, represents a particularly significant capability enhancement. The three Polish military reconnaissance satellites, built by the Finnish company, give the Polish armed forces for the first time an independent real-time intelligence collection capability that does not depend on allied data sharing, fundamentally changing Poland's situational awareness along its eastern border.
