German authorities recently arrested a 54-year-old Greek national and a 37-year-old Romanian, accused of attempting to sabotage German Federal Navy (Bundeswehr) vessels at the Port of Hamburg in 2025.
According to German authorities and press reports, the case is being viewed as part of a rising tide of hybrid threats targeting critical military infrastructure across Europe.
Sabotage of the German Navy’s corvette “Emden”
The two suspects allegedly used their legal access as port workers to infiltrate high-security shipyards. Reports from ARD-Tagesschau and ZDF detail “targeted and dangerous interventions” on several K130-class corvettes, specifically the Emden.
During inspections at the Blohm+Voss shipyard in early 2025, investigators discovered:
- Engine tampering: Over 20kg of gravel and grit poured into the engines.
- Structural damage: Drilled water pipes and removed fuel tank caps.
- Electronic interference: Disabling of safety switches and electronic monitoring systems.
The Hamburg Prosecutor’s Office has classified the acts as “attempted sabotage of defense materiel,” a charge far graver than simple property damage, as it directly threatens the national security and operational readiness of the Federal Republic.
“Low-level agents” and foreign interests
A central focus of the investigation is whether the duo acted as “low-level agents” for a foreign power.
The sabotage of the K130-class corvettes—strategic vessels used for maritime surveillance—is being analyzed through the lens of the NATO-Russia confrontation.
While Moscow denies involvement, Western security circles cited by Der Spiegel and Focus suggest these acts align with a pattern of Russian-sponsored hybrid warfare. Vice Admiral Jan Christian Kaack had previously warned in 2024 of intentional damage to multiple units, leading to heightened security protocols that eventually helped trap the suspects.
