In 2025, Norway experienced a significant decline in the number of foreign submarine visits, with only 33 submarine arrivals reported. This figure marks a reduction of 14 visits from 2024 and 21 visits compared to 2023. The statistics were released by the Norwegian Armed Forces' Operational Headquarters (FOH), highlighting the changing dynamics of military naval activities in Norwegian waters.

The report indicates that out of these 33 foreign submarine arrivals, 21 were powered by nuclear reactors, underscoring the presence of advanced military technology in the region. The decrease in foreign submarine activity raises concerns regarding international naval engagement and the implications for Norway's defense strategies, particularly in the context of regional security dynamics and relationships with foreign nations.

Overall, this trend could reflect broader geopolitical shifts, including increased scrutiny of military activities or changes in strategic priorities among foreign navies. It also highlights the importance of monitoring foreign naval traffic for national security, suggesting that the Norwegian military may need to adapt its operational focus in response to the evolving maritime landscape.
