GNSS Interference in Nakhodka Bay

Summary:

In August 2025, AIS data for nearly 98 ships, primarily tankers, was disrupted across Russia’s Far East, specifically around Nakhodka Bay and the Kozmino oil terminal, as interference began on August 6. This AIS blackout, attributed to third-party GNSS manipulation, rendered real-time vessel tracking ineffective, especially during cargo loading, and severely hindered maritime visibility. Analysts interpret this interference as a strategic effort to conceal oil export operations, possibly linked to sanction evasion, amid a broader pattern of Russian naval and electronic warfare activity across the region.
