Poland’s First F-35A Lightning IIs Land at Łask: NATO’s Eastern Flank Goes Fifth-Generation

Poland’s Air Force welcomed its first three F-35A Lightning II fighters at the 32nd Tactical Air Base in Łask on May 22, 2026. According to The Defense Post, Deputy Prime Minister and Defence Minister Władysław Kosiniak-Kamysz attended the ceremony alongside deputy defence ministers Paweł Bejda and Cezary Tomczyk. The delivery marks the first frontline operational deployment of Lockheed Martin’s fifth-generation fighter on NATO’s eastern flank.

Six Years From Signature to Tarmac

The contract — codenamed Harpia (Harpy) — was signed during the Trump administration’s first term in January 2020. Defense Express reports that Poland’s first tail-numbered F-35As actually rolled off the line in 2024, but stayed in the United States while Polish pilots and maintainers completed type-conversion training. The May 22 arrival at Łask comes roughly six years after contract signature — broadly in line with current JSF delivery cadences across Europe, but a long road for one of NATO’s most vocal frontline modernisers.

What’s in the Delivery Package

Army Recognition reports that the package extends beyond the airframes. Lockheed Martin’s logistics support, spare-parts inventory, ground support equipment, IT infrastructure and eight full-mission flight simulators, plus pilot and maintainer instruction, are all included. The program is engineered to sustain operational readiness through 2030. The F-35As will complement — not replace — Poland’s existing F-16C/D Block 52+ fleet, building a layered manned-fighter posture.

Eastern Flank Context

Poland is now NATO’s top defence spender, allocating more than 4.8% of GDP to armed-forces modernisation in 2026. The F-35 delivery announcement landed in the same week as US President Trump’s pledge of an additional 5,000 troops to Poland, and NATO Secretary-General Mark Rutte’s public welcome. At the ceremony, Minister Kosiniak-Kamysz stated that “the F-35s, together with the weaponry purchased in recent months, are changing the face of our armed forces.”

Poland is wrapping the F-35 fleet into a broader deterrence package that already includes HIMARS rocket artillery, K2 Black Panther tanks, K9 Thunder howitzers and Patriot PAC-3 air defence — a posture that makes Warsaw the fastest-modernising power on NATO’s eastern flank.

Why It Matters for Turkey

Poland’s transition to fifth-generation airpower puts a fresh spotlight on the regional cost of Turkey’s 2019 removal from the F-35 programme under CAATSA sanctions following the S-400 acquisition. With Poland entering NATO’s eastern flank as a fifth-gen operator, Turkey is closing the same capability gap on indigenous terms with the TUSAŞ KAAN national combat aircraft programme. KAAN’s TF-X airframe, sovereign production line, sensor suite and TÜBİTAK SAGE munitions integration deliver a domestic package free of the supply-chain leverage that defines F-35 partnerships.

Three takeaways for Turkish industry: (1) Poland’s six-year wait demonstrates the real European F-35 delivery cadence — KAAN’s 2028 target is competitive against that benchmark. (2) Poland procured eight full-mission simulators for 32 jets; training-infrastructure investment is the invisible but decisive leg of any fighter programme. (3) Poland’s F-35s sit alongside the F-16 fleet rather than replacing it — much as KAAN will operate in a mixed fleet with Turkey’s upgraded F-16s.

Frequently Asked Questions

When was the Polish F-35 contract signed and what is the value?
The Foreign Military Sales (FMS) contract was signed in January 2020. The total value is USD 4.6 billion, covering 32 F-35A Lightning II aircraft, logistics support, spare parts, IT infrastructure and eight full-mission simulators.

Why were aircraft built in 2024 only delivered in 2026?
Polish pilots and maintainers completed type-conversion training in the United States; the airframes remained on US soil during that period. The first three were handed over once training milestones were met, arriving at Łask’s 32nd Tactical Air Base on May 22, 2026.

Where will Poland base its F-35s?
The main base is the 32nd Tactical Air Base in Łask, central Poland. The base already hosts the F-16C/D Block 52+ fleet; the F-35s join as the second fifth-generation-capable squadron at the site.

Why was Turkey removed from the F-35 programme?
Turkey was removed from the F-35 programme by the United States in 2019 after acquiring Russia’s S-400 Triumf air defence system. The decision was made under the CAATSA sanctions framework; the 100 F-35As ordered by Turkey were not delivered and Turkey’s industrial partner status was terminated.

When will the KAAN programme fill the F-35 gap?
TUSAŞ KAAN national combat aircraft initial operational deliveries are targeted for 2028. KAAN is designed with fifth-generation features — low observability, AESA radar, internal weapons bay — with sovereign production removing the foreign-supply dependencies that define F-35 partnerships.

What does Poland’s F-35 entry mean for NATO’s eastern flank?
Poland becomes the first NATO eastern-flank nation to field a fifth-generation fighter fleet. Combined with K2 tanks, HIMARS, K9 howitzers and Patriot PAC-3 air defence, this materially shifts the alliance’s deterrence posture against Russian airpower in the region.

Bottom Line

With Poland’s first three F-35As wheels-down at Łask, NATO’s eastern flank has formally entered the fifth-generation era. When the 32-jet fleet completes in 2029, Warsaw will operate the alliance’s most potent air combat node on the Russian frontier. For Turkey, the milestone returns the spotlight to the KAAN programme’s 2028 schedule and to the discipline of indigenous production — the door that closed on F-35 in 2019 is meant to reopen with KAAN.
