Poland said it scrambled two fighter jets this week to intercept a Russian Il-20 reconnaissance plane flying without a transponder over the Baltic Sea, the latest in a growing series of incidents testing NATO’s air defenses in Eastern Europe.
The Polish Armed Forces confirmed that the Ilyushin-20 — a Cold War–era turboprop aircraft used by Russia for intelligence gathering — was detected on Tuesday just outside Polish airspace.
The aircraft’s transponder had been switched off, effectively rendering it invisible to civilian radar systems. “Thanks to the high combat readiness and professionalism of our pilots, the operation was carried out quickly, effectively, and safely,” the military said.
Two Polish MiG-29s intercepted, identified, and escorted the Russian plane away from the boundary of Polish-controlled airspace.
Warsaw said the aircraft never entered its national airspace but called the flight a clear provocation, part of Moscow’s pattern of “probing” NATO’s defenses since its full-scale invasion of Ukraine in 2022. The Russian defense ministry has not commented.
The Baltic Sea region has become one of Europe’s most sensitive flashpoints. Poland, which borders Russia’s Kaliningrad exclave, has reported multiple airspace violations and drone incursions in recent months.
On September 10, Polish authorities raised the alarm over several unmarked drones crossing from the east, prompting temporary airspace restrictions.
Similar incidents have occurred in Denmark and Lithuania, where mysterious drone swarms and even helium-filled balloons allegedly launched from Belarus have forced repeated airport closures.
Estonia, another NATO ally on the Baltic coast, recently invoked Article 4 of the alliance’s charter — calling for emergency consultations — after three Russian fighter jets violated its airspace in late September.
NATO condemned the incursions as “escalatory” and warned that they “risk miscalculation and endanger lives.”
Western analysts say Moscow’s flights near NATO borders serve two purposes: gathering electronic intelligence on allied radar and response systems, and testing how quickly NATO interceptors can scramble.
Turning off transponders, they note, heightens the danger of midair collisions in crowded commercial corridors.
While the Polish military described this latest intercept as routine, the frequency of such encounters underscores how the Baltic has become an active front in the wider standoff between Russia and NATO — a contest now fought less through open confrontation and more through dangerous games of brinkmanship in the skies.
