The number of damage incidents to underwater infrastructure in the Baltic Sea has dropped significantly since the launch of NATO’s Baltic Sentry mission and an increased presence of the Latvian Navy, according to Navy Commander Polenc. Latvian authorities report that they have not recorded any instances of anchors dragging and damaging cables over the past year, marking a shift from the string of undersea infrastructure failures that occurred more than a year ago.
The Baltic Sentry observation mission was established by NATO following the damage to several telecommunications and energy cables in the Baltic Sea region more than a year ago.
Monitoring the ‘Shadow Fleet’
The Latvian Navy maintains a regular inspection schedule for vessels identified as part of the Russian “shadow fleet” whenever they enter Latvian ports. Commander Polenc confirmed that these inspections are conducted on all vessels deemed suspicious, though he did not disclose specific figures regarding the frequency or number of these operations. While the Navy closely monitors these ships, Polenc noted that the Baltic Sea remains a free shipping zone, with established maritime routes overlapping with critical underwater infrastructure.
The challenge for the Latvian Navy lies in balancing the legal reality of free maritime navigation with the security imperative of protecting sensitive subsea assets. Because international law protects the right of passage, authorities must rely on targeted inspections of “suspicious” vessels rather than broad exclusion zones, a strategy that requires precise intelligence to remain effective.
Assessing Threats from Drones
While some public commentary suggests that Russian vessels could serve as platforms for launching drones toward NATO territory, Commander Polenc stated that such claims currently lack specific evidence. The Latvian Navy has observed suspicious drones over the sea, but the current policy is to limit activity to monitoring and data collection unless the craft poses a direct, immediate threat to naval vessels. This approach mirrors broader regional concerns, as NATO launched the Eastern Sentry operation in September of last year to bolster the alliance’s eastern flank following drone sightings over Poland and Denmark.
Future Operational Outlook
Security in the Baltic region remains tied to the continued presence of observation missions like Baltic Sentry and Eastern Sentry. If drone activity or maritime traffic patterns shift, the Latvian Navy may be forced to adjust its monitoring thresholds. Analysts might expect that as long as the “shadow fleet” continues to operate in the Baltic, port inspections will remain a primary tool for detecting potential security risks to underwater infrastructure.
Frequently Asked Questions
What has changed regarding underwater cable safety?
According to Commander Polenc, there have been no reported incidents of anchors damaging cables in the past year, a significant decrease attributed to the increased presence of the Latvian Navy and the Baltic Sentry mission.
How does the Latvian Navy handle the Russian ‘shadow fleet’?
The Navy conducts regular inspections of suspicious vessels whenever they enter Latvian ports, though the exact number of these inspections is not public.
What is the stance on drones over the Baltic Sea?
The Navy monitors and gathers information on suspicious drones, but they do not take active measures unless the drones pose a direct threat to naval vessels, noting that evidence is required to support claims that ships are being used as launch platforms.
Do you believe that increased naval patrols are sufficient to deter future incidents of underwater infrastructure damage in the Baltic?
