On September 10, 2025, Russian drones supported by Iranian assistance violated Polish airspace, including 19 penetrations, marking the largest known NATO airspace violation requiring NATO aircraft to engage targets; a similar drone incursion occurred in Romanian airspace four days later.

Summary

On September 10, 2025, Polish officials reported 19 Russian drones violated their airspace in what was described by Polish Foreign Minister Radosław Sikorski as a deliberate Kremlin provocation testing NATO's resolve. NATO scrambled Polish F-16s, Dutch F-35s, and an Italian surveillance aircraft to defend the airspace, shooting down several drones, marking reportedly the first time NATO aircraft engaged enemy targets over alliance airspace. The drones were Gerbera models, Russian-produced and often used as decoys. On September 14, Romanian defense officials reported a breach by a Russian Geran-2 drone, identified as the Iranian-designed Shahed-136. Debris from Russian drones has been found in both countries previously. Iranian assistance, including a $1.75 billion 2023 deal, has enabled Russia to produce thousands of these drones monthly, expanding their long-range strike capabilities. Iran also provided Russia with Fath-360 ballistic missiles, confirmed in 2024, increasing Moscow's missile threat to Ukraine and NATO. Following the incursions, NATO launched the "Eastern Sentry" activity to enhance eastern flank defenses, incorporating lessons from Ukraine like the use of cheap interceptor drones and passive detection. European capitals with Washington are urged to enforce sanctions on Iran to deter further military support to Russia. NATO leaders deem the response successful but costly, firing expensive AMRAAM missiles to shoot down comparatively low-cost drones. These drone incursions represent a growing hybrid threat facilitated by Iranian support.

Classification

Confidence: High

Aggressor true: Russian drone incursions into NATO airspace with Iranian assistance are explicitly documented. Signal_type HYBRID_SIGNAL as the primary subject is the hostile drone incursion incidents, including engagement of enemy targets in alliance airspace, rather than NATO's defensive response measures.

NATO aircraft including Polish F-16, Dutch F-35 fighters, and an Italian surveillance plane engaged and shot down several drones, reportedly the first NATO engagement with enemy targets in alliance airspace. The drones used were primarily Gerbera models, Russian-produced with Iranian assistance. Four days later, on September 14, Romania reported a breach by a Russian Geran-2 drone, Iranian-designed Shahed-136, tracked by Romanian F-16s. Iran has supported Russia’s long-range strike capabilities by transferring drones since 2022 and enabling Russian domestic production through a $1.75 billion deal signed in 2023. Russia produces approximately 2,000 Geran-2 drones monthly with plans to increase to 5,000. Iran also provided Fath-360 close-range ballistic missiles in 2024, augmenting Moscow's missile arsenal threat to Ukraine and NATO. NATO responded with the \"Eastern Sentry\" initiative to bolster defenses on its eastern flank, incorporating Ukrainian lessons such as deployment of cheap interceptor drones and passive detection networks. European and U.S. efforts continue to focus on enforcing sanctions on Iran to curb its military support to Russia.",
