Danish patrol boat photographs Russian SS-750 with mini-sub gear east of Bornholm, four days pre-blasts.
On 22 September 2022 a Danish patrol boat captured about 26 photographs of the Russian Navy vessel SS-750 (known to be capable of deploying a Priz-class mini-submersible) operating east of Bornholm, days before the major underwater explosions of the Nord Stream pipelines. The Danish Defence Command confirmed existence of the images, describing them as “intelligence material” though not all details publicly released. Analysts pointed to the SS-750’s capabilities—lifting, deployment, recovery—as consistent with potential placement of underwater devices. While the vessel’s presence alone doesn’t constitute proof of sabotage, the documentation established a strong presence of Russia’s underwater-capable craft in the Danish maritime zone at a critical time. The pattern tied into a broader “ghost ship” programme mapping seabed infrastructure across northern Europe, in which Denmark’s offshore wind farms and cable corridors are embedded. Danish authorities used this case to brief NATO and regional partners and to refine surveillance of seabed and EEZ spaces. It elevated awareness of pre-sabotage reconnaissance as a component of hybrid warfare rather than direct attack. Though no direct act of sabotage was attributed to this event, it signalled Russia’s footprint in Danish maritime security space and helped shift Denmark’s posture toward proactive undersea infrastructure monitoring.
