German Navy Investigates Surge in Suspected Sabotage Cases Amid Security Concerns]
Investigators are examining a growing number of suspected sabotage incidents targeting the German navy, with ten potential cases reported since the beginning of 2025, according to CORRECTIV.
In the most recent incident at the end of February 2026, a two-centimetre-wide slit was discovered in the fuel line of the frigate “Rheinland-Pfalz” while the vessel was docked in Wilhelmshaven. The Bundeswehr believes the damage was deliberate.
“In principle, we can confirm that the threat situation for seagoing units in shipyards, as well as naval vessels under construction, has changed as a result of several suspected cases of sabotage,” a Bundeswehr spokesperson said.
The case was reported to investigative authorities in March, but the investigation was later discontinued by the public prosecutor’s office in Oldenburg. Investigators were unable to determine whether the damage was caused by intentional interference, wear and tear, or a material defect.
Prior Sabotage Incidents
A separate case of suspected sabotage emerged during an inspection at the Blohm+Voss shipyard in Hamburg in January 2025. During examination of the warship “Emden”, inspectors discovered several kilograms of abrasive material in the engine room that could have caused significant damage. Hamburg’s criminal investigation department and public prosecutor’s office concluded the incident was likely sabotage. A 37-year-old Romanian nationals and a 54-year-old Greek national, both believed to have worked in the Hamburg port area, were arrested in connection with the incident, though prosecution did not identify any instigators.
Previous incidents included cases where cable looms were severed on one naval vessel and used oil was deliberately introduced into another ship’s drinking water system. In both instances, the public prosecutor’s office discontinued proceedings.
Russian security services are suspected of orchestrating these attacks, according to Western intelligence circles. Germany is viewed as a primary target due to its strong support for Ukraine in opposing Russia’s invasion. The Federal Office for the Protection of the Constitution (BfV) and Federal Criminal Police Office (BKA) have warned of so-called “disposable agents” – petty criminals recruited via social media platforms and incentivized to carry out sabotage. These operatives are typically compensated in cryptocurrency, with payments ranging from several hundred euros for basic tasks to tens of thousands of euros for attacks on NATO military equipment.
