Summary

Sweden’s naval chief warns on April 9, 2024, that Russian GPS jamming emanating from Kaliningrad disrupts Baltic Sea navigation, demanding NATO action.

On April 9, 2024, Sweden's naval chief publicly condemned ongoing Russian GPS interference in the Baltic Sea, specifically citing emissions from Kaliningrad as the source. The interference affects shipping and air navigation safety, with growing evidence linking it to Russian electronic warfare exercises. Researchers have documented this as part of a wider pattern of deliberate GPS jamming and spoofing in the Baltic region to degrade navigation reliability. The Swedish naval chief highlighted the risk to merchant vessels and aircraft, urging NATO to take coordinated action to counteract these electronic threats and ensure maritime and aviation security in the Baltic region.

Classification

Confidence: High

High confidence due to explicit attribution of hostile Russian GPS jamming from Kaliningrad targeted on Baltic Sea navigation, alongside the Swedish naval chief's call for NATO defensive action, indicating both aggression and defense preparation.
