Swedish Navy suspects Russian shadow fleet espionage activities near Gotland in the Baltic Sea on April 2024.
On April 23, 2024, the Swedish Navy, led by Commander Ewa Skoog Haslum, confirmed suspicions that the Russian shadow fleet is spying in the Baltic Sea near Gotland. Russian shadow fleet vessels, often cargo ships equipped with special antennas and masts, are suspected of using hybrid warfare tactics including intelligence gathering and signals espionage. Swedish authorities have previously observed concrete preparations for attacks linked to these vessels. The navy is monitoring the movements focusing on security and environmental concerns, with suspicions that these ships function as spy platforms under the guise of commercial operations. This activity exemplifies Moscow's expanding unconventional naval tactics near Swedish waters, highlighting ongoing security challenges. The situation is under active surveillance, with the navy emphasizing the complex threat posed by these unmarked vessels operating under international sanctions and near Swedish territorial waters.
Confidence: High
Classified as aggressor event because the Swedish Navy confirms that Russian shadow fleet vessels operating near Gotland are suspected of espionage and hybrid warfare activities, including signals intelligence via antennas and masts on these ships. There is no indication that the article describes Swedish defensive actions; it focuses on monitoring and suspicion of hostile activities.
