Prosecutors arrested a 37-year-old Romanian and a 54-year-old Greek man employed at Hamburg's Blohm+Voss yard for tampering with the K130-class corvette Emden and possibly others last year. They poured over 20 kilograms of metal into engine blocks, punctured water lines, removed fuel caps, and disabled fuses—acts discovered during January 2025 inspections that could have caused major damage or delays to Germany's Baltic Sea patrols. The case highlights insider risks amid NATO tensions, with investigators checking for more sabotage and no motive yet confirmed.
