Novorossiysk (Russian submarine) and Boikiy (Russian corvette) shadowed through Dutch North Sea EEZ.

The Koninklijke Marine (Royal Netherlands Navy) reported that it monitored and escorted a Russian submarine (Novorossiysk) and a Russian corvette (Boikiy) while they transited the Dutch-managed section of the North Sea. The Dutch ministry emphasised that while international law permits innocent passage, the escorting and shadowing of the vessels is a routine yet heightened measure given rising concern about reconnaissance and possible sabotage of under-sea infrastructure. The incident reflects how hybrid-warfare can involve naval assets navigating geopolitical grey zones rather than overt combat.The geographic aspect emphasises the Dutch offshore waters and underscores that critical infrastructure—such as submarine cables, pipelines and wind-farm connections in the North Sea—may be subject to reconnaissance by foreign military assets. Intelligence and defence commentary, from the Militaire Inlichtingen‑ en Veiligheidsdienst (MIVD), warns that the presence of such naval assets may signal preparatory mapping ahead of sabotage or disruption of infrastructure beneath the sea surface.
