Poland Receives First F-35s and Retires MiG-29 Fleet
Recent deliveries of F-35A Lightning II fighters to Poland mark a major milestone in NATO’s eastern air defenses. Three Polish F-35s arrived at the 32nd Tactical Air Base in Łask on 22 May 2026, the country’s first operational fifth-generation jets. Publicly available information from Poland’s Senate indicates that all 32 aircraft on order are scheduled to be delivered by the end of the decade, giving Warsaw one of the region’s most modern tactical air fleets.
The new jets are replacing Poland’s MiG-29 Fulcrum fleet, a legacy of Warsaw Pact procurement. In parallel with its F-35 program, Warsaw has been transferring remaining Soviet-era MiG-29s to Ukraine. According to Polish state news agency coverage, Poland had already supplied 14 MiG-29s by 2023 and signaled plans in late 2025 to donate its remaining Fulcrums, effectively closing the chapter on Russian-designed fighters in Polish service.
This twin track of modernizing with U.S.-built aircraft while divesting Soviet designs illustrates a broader political and operational realignment. For Poland, a state that borders both Russia’s Kaliningrad exclave and war-torn Ukraine, the move brings tighter interoperability with U.S. and NATO air forces and reduces dependence on Russian-origin parts, technical data, and overhaul capacity.
Poland’s F-35 purchase also complements earlier decisions to buy other U.S. platforms and precision weapons, reinforcing a pattern of deepening defense-industrial ties. Analysts note that as more F-35s arrive and MiG-29s leave service, Polish pilots, maintainers, and planners will increasingly train and operate within the same digital, networked environment as other F-35 operators across Europe.
Finland’s F-35s to Replace Hornets on NATO’s Northern Flank
While Poland begins operating its F-35s, Finland is preparing to receive its first aircraft under a 64-jet program chosen in 2021 to replace its Boeing F/A-18 Hornet fleet. The Finnish Ministry of Defence’s published material states that deliveries are due to start in 2026, with F-35s entering service at home bases between 2028 and 2030 as Hornets retire.
Helsinki’s selection of the F-35 gained added significance after Finland joined NATO in 2023. Defense policy assessments highlight that the aircraft will sit at the heart of air defenses guarding the alliance’s extensive new border with Russia. Studies from European and U.S. security institutes describe Finland’s geography, long land frontier, and proximity to the Arctic as critical factors shaping NATO deterrence plans, making the choice of a stealthy, networked fighter highly consequential.
Finland’s industrial participation is another dimension of the program’s impact. Government releases indicate that F-35 engines will be assembled in the city of Nokia and front fuselage sections in Jämsä, anchoring high-tech aerospace work inside the country. These arrangements both support long-term sustainment and help ensure that critical maintenance capability is not reliant on Russian or other potentially contested supply chains.
For travelers and observers, the shift will gradually change the hardware seen at Finnish bases and air shows, as classic Hornets give way to angular F-35 silhouettes. More broadly, it signals that northern Europe’s air forces are converging on a common platform for shared training, quick cross-border deployments, and integrated air and missile defense.
From Soviet Designs to a Western Fifth-Generation Standard
Poland’s and Finland’s F-35 decisions sit within a wider European pattern of moving away from Soviet and Russian fighter designs that once populated many inventories. After Russia’s full-scale invasion of Ukraine in 2022, several NATO members accelerated retirement of MiG-29 and other legacy fleets, sending aircraft and air defense systems eastward in support of Kyiv. Slovakia, for example, has already transferred its MiG-29s and is transitioning to U.S.-built F-16s, while Poland’s donations of MiG-29s were structured around the arrival of newer Western platforms.
At the same time, multiple European air forces that historically operated Western fourth-generation types are stepping up to the F-35. Public procurement records and manufacturer data show confirmed selections across the continent, including Germany, Switzerland, Belgium, Denmark, Norway, Italy, the Netherlands, the Czech Republic, Greece, Romania and others. A recent European defense-industry study notes that 13 European countries are now in the F-35 program as either partners or foreign military sales customers.
This consolidation around a single fifth-generation design contrasts sharply with the past landscape of diverse national and Soviet-derived fleets. For former Warsaw Pact states, the shift carries strong strategic and symbolic weight. It reduces or ends reliance on Russian-origin engines, avionics, and maintenance hubs, and aligns air forces with the U.S.-led logistics and training ecosystem that underpins NATO air power.
It also has implications for Russia’s aerospace footprint. As countries from Central Europe to the High North select U.S. and European fighters instead of Russian models, Moscow faces fewer export opportunities and diminished leverage connected to spare parts, overhauls, and training for older MiG and Sukhoi fleets abroad.
F-35 Network Effects Across NATO and Beyond
The growing number of F-35 users is creating network effects within NATO and partner coalitions. According to public figures from the manufacturer, more than 1,150 F-35s are in service worldwide with over a dozen nations, and the aircraft has accumulated more than one million flight hours. Recent contracts outlined in defense trade publications show new production lots covering nearly 300 aircraft for U.S. services, partner nations, and additional foreign military sales customers.
For European operators, this translates into larger multinational training events, more shared tactics, and the ability to deploy seamlessly across borders. Existing F-35 users such as Italy, the United Kingdom, Norway, Denmark and the Netherlands are already flying the jet routinely in NATO air policing missions and multinational exercises. As Poland and, later in the decade, Finland join those rotations, the alliance’s northern and eastern air posture will increasingly rest on a common stealth platform with compatible sensors and data links.
Analysts also point to the aircraft’s software-driven upgrade path as a key factor for long-term planning. Block improvements are intended to introduce new sensors, weapons, and electronic-warfare tools without changing the basic airframe, which simplifies cooperative modernization. Countries like Canada, Greece, the Czech Republic and Romania have all cited lifecycle considerations and interoperability when describing why they selected the F-35 over other Western designs.
Beyond NATO, Indo-Pacific allies including Japan, South Korea and Singapore are also procuring the jet, reinforcing a global community of operators that share training, sustainment concepts and in some cases industrial work. The result is an increasingly integrated F-35 ecosystem spanning Europe, North America and the Asia-Pacific, with Europe’s front-line states now deeply embedded in that network.
Strategic Implications for Travelers and Regional Stability
For international travelers, these shifts in airpower may be most visible at military open days and in the growing number of joint exercises hosted across Europe. Bases in countries such as Poland and Finland previously associated with legacy Soviet or early-generation Western fighters will feature stealth aircraft and multinational F-35 deployments, reflecting closer security cooperation with North American and European partners.
From a regional stability perspective, security think-tank reports argue that the concentration of F-35 operators along NATO’s northern and eastern flanks is intended to strengthen deterrence by denial. Fifth-generation jets offer enhanced ability to detect and track potential threats at long range, coordinate with ground-based air defenses, and operate in contested electronic environments, which is viewed by many governments as central to preventing miscalculation or coercion.
At the same time, European policy debates continue around balancing investments between U.S.-designed platforms and emerging European fighter initiatives. Some analysts caution that heavy reliance on a single foreign design can create political and industrial dependencies of its own, even as it reduces exposure to Russian-origin systems. These discussions are likely to intensify as F-35 deliveries ramp up and as new European combat-aircraft projects seek long-term funding.
For now, however, Poland’s initial F-35 arrivals and Finland’s impending deliveries underscore a clear trend. Alongside other recent selections across Europe, they signal that many of Russia’s closest neighbors are betting their air-defense futures on a shared Western stealth fighter, reshaping the continent’s military aviation map for decades to come.
