On July 2, 2025, Sweden's maritime authority warned of extensive Baltic Sea interference affecting radar and GNSS navigation systems, escalating risks for maritime security.
On July 2, 2025, the Swedish Maritime Authority publicly disclosed a significant rise in interference incidents impacting maritime navigation across the Baltic Sea. While earlier attacks primarily disrupted GNSS, AIS, and DGPS signals, this new series of interference events includes radar disruption, which is a critical fallback navigation system for vessels. The interference was detected widely, including on NAVTEX terminals that disseminate maritime safety information. The attacks cover all GNSS frequency bands, indicating more sophisticated and widespread jamming efforts than previously observed. This escalation occurs amid ongoing tensions and previous sabotage incidents in the Baltic region, raising serious concerns about maritime operational security and the safety of shipping in these waters. The situation underscores the increasing hybrid warfare tactics that target critical maritime infrastructure, potentially threatening commercial and military navigation.
Confidence: High
Classified as aggressor event because the Swedish Maritime Authority warns of hostile interference affecting critical maritime navigation aids including radar, GNSS, AIS, and NAVTEX, indicating an ongoing coordinated jamming attack in the Baltic Sea. No defensive or countermeasure actions by allied states are described in the source.
