On Wednesday, Sept. 23, a Russian‑operated Mi‑8 helicopter flew from the Russian exclave of Kaliningrad into the sovereign airspace of NATO member Poland, remaining inside for just 42 seconds and penetrating to a maximum depth of about 300 metres (328 yards). The incursion was reported by the Polish Army Operational Command on its official X account.

Polish authorities responded immediately, dispatching fighter aircraft to intercept the intruding helicopter while ground‑based air‑defence units and other assets were placed on alert. The Operational Command described the episode as a test of Poland’s air‑defence readiness.

The brief breach comes amid heightened vigilance across Poland’s borders, which have been on alert since Russia’s invasion of Ukraine in 2022. Polish officials have repeatedly warned that any unauthorized entry into their airspace could signal a broader escalation, and they have been closely monitoring activity from the Kaliningrad region, a Russian military enclave bordering the Baltic states and Poland.

The Russian embassy in Warsaw did not immediately respond to a Reuters request for comment on the incident, leaving the diplomatic explanation for the flight unclear.
