Since early 2025, at least ten suspected sabotage incidents have targeted the German navy, including deliberate damage to naval vessels, such as a slit in the fuel line of the frigate Rheinland-Pfalz, foreign materials found in engine rooms, cut cable looms, and contamination of drinking water systems. Investigations have been opened but in some cases dropped due to unclear evidence. Two foreign nationals were arrested in connection with one incident at the Blohm+Voss shipyard in Hamburg. Western security services and German domestic agencies suspect Russian involvement, attributing the acts to low-level agents recruited and incentivized via social media and paid in cryptocurrency to carry out sabotage against NATO military assets. Germany is viewed as a key target due to its support for Ukraine against Russia.
