Summary

On June 17, 2025, Poland detected extensive GPS signal interruptions over the Baltic Sea, attributing them to Russian electronic warfare causing risks to civil aviation and drone control in NATO countries.

Poland, on June 17, 2025, announced ongoing GPS signal disruptions over the Baltic Sea linked to Russian military electronic warfare efforts targeting NATO countries in the region, including the Baltic States and Northern Europe. The Polish Defense Minister confirmed that these disturbances encompass jamming and spoofing techniques, leading to significant operational challenges such as the diversion of a passenger flight and drone navigation failures. Consequently, Polish authorities established a special security committee that issued operational and safety recommendations to military and civil aviation bodies. Lithuanian defense officials also reported the widening scope of GPS interference near its coast and adjacent waters by the Kaliningrad region, raising concerns about the safety of civilian maritime and aerial navigation. The repeated disruptions indicate an escalated Russian effort to undermine navigation systems and assert hybrid warfare pressure on Baltic Sea states.

Classification

Confidence: High

The event explicitly describes deliberate Russian GPS signal interference classified as sabotage, constituting aggressor hostile activity. Simultaneously, Polish and NATO countries' security responses, including military and civil aviation coordination and issuance of warnings, qualify as defense preparations.
