Summary

On June 12, 2025, Lithuania's Deputy Defense Minister Karolis Aleksa stated that Russia is expanding the scope of blocking GPS signals in the Baltic region, affecting Lithuania and neighboring North Baltic countries. The interference, attributed to Russia's use of electronic warfare systems, has been increasing in scale and is likely malicious, aiming to cause significant damage. The disruption has led to accidents and loss of drone control, especially near Lithuania's Baltic Sea coast in the vicinity of the Curonian Lagoon, close to the Russian Kaliningrad region. Notably, by the end of May 2025, GPS jamming and spoofing in the eastern Baltic Sea have posed threats to civilian shipping, including cases where ships disappeared from radar or transmitted incorrect AIS locations. These actions are analyzed as part of Russia's response to Lithuania and Ukraine strengthening their defenses amid ongoing conflict.

Classification

Confidence: High

The article explicitly describes Russian hostile electronic warfare actions targeting GPS signals in the Baltic region, constituting clear aggressor activity. Simultaneously, Lithuanian and Baltic states' efforts to monitor, respond, and strengthen defenses against this threat qualify as defense preparations. The named actors (Russia, Lithuania) and specific hostile actions (GPS jamming/spoofing) provide high confidence.

  "description": "Lithuanian Deputy Defense Minister Karolis Aleksa reported that Russia is expanding the scope of blocking GPS signals in the Baltic region, affecting Lithuania and other North Baltic countries. This escalation in electronic warfare activities is characterized by increased jamming and spoofing of GPS signals, particularly near the Curonian Lagoon close to the Russian Kaliningrad region. The disruptions interfere with drone control and have caused accidents. The Russian interference is viewed as a response to Lithuania and Ukraine's defensive measures amid the war in Ukraine. Additionally, Russia's jamming of GPS signals in the eastern Baltic Sea has threatened civilian maritime navigation, causing ship radar disappearances and incorrect AIS transmissions. These actions reflect deliberate, likely malicious, electronic warfare targeting civilian and military navigation systems in the region.",
