In recent months there have been increasing attacks on this critical infrastructure. In the Baltic, cables and pipelines critical to Europe have been attacked. A Chinese ship has been caught cutting undersea cables to Taiwan. These types of attacks are increasingly significant.
Western countries are concerned Russia is sabotaging subsea cables that transmit 99% of the world’s data, including an estimated US$10 trillion a day in financial transactions. In response, the North Atlantic Treaty Organization (NATO) launched its new Baltic Sentry mission earlier this month after several cables under the Baltic Sea were damaged or severed in 2024, allegedly by Russia-backed vessels. On Sunday, Swedish authorities seized a ship suspected of damaging a data cable running under the sea to Latvia.

Assessing the Claims
Attacks on Undersea Infrastructure in the Baltic
- In late September 2022, explosions severely damaged the Nord Stream 1 and 2 gas pipelines in the Baltic Sea. While investigations are ongoing, many observers regard these incidents as deliberate sabotage, underscoring the vulnerability of critical undersea infrastructure.
- Beyond the pipelines, there have also been reports of suspicious damage to undersea data cables in Northern Europe (e.g., the Shetland/Faroes cables), though conclusive proof of who (if anyone) orchestrated such damage is difficult to obtain.
Undersea Cables Cut Near Taiwan
- In February 2023, two undersea cables connecting Taiwan’s outlying Matsu Islands to Taiwan’s main island were severed in close succession. Investigations pointed to two different vessels—a suspected Chinese fishing boat for one cable and a cargo vessel (originating from another country) for the other.
- While Taiwanese officials noted that these incidents could have been accidental (for instance, fishing boats often drag anchors or nets along the seafloor), they also acknowledged the possibility of deliberate interference. However, there was no publicly disclosed “smoking gun” that conclusively proved sabotage by the Chinese government.
- To date, most reporting on these events stops short of declaring that a Chinese ship was definitively caught in the act of maliciously cutting cables. Rather, the incidents have heightened concerns about Beijing’s potential to disrupt Taiwan’s communications in a future crisis.
Why Undersea Cables Matter
- Global Data Backbone: Roughly 95%–99% of international data—encompassing financial transactions, internet traffic, diplomatic communications—travels via fiber-optic cables on the ocean floor.
- Economic Impact: With many trillions of dollars’ worth of daily transactions dependent on cable integrity, any disruption can cause immediate financial and logistical turmoil.
- Geopolitical Significance: Because these cables are so crucial, adversaries view them as both a strategic vulnerability and a potential pressure point in times of conflict. Tapping or cutting cables can yield intelligence or inflict economic damage.
Attribution and Challenges
- Difficulty of Policing: The ocean floor is vast, and cables are often unguarded; investigating a cable break in deep waters can take days or weeks, and the cause (accident vs. sabotage) can remain unclear.
- Cover of ‘Accidents’: Fishing nets, anchors, or natural disasters (like underwater landslides) regularly cause cable damage, making it easier for saboteurs to hide malicious intent behind plausible deniability.
- Legal/Operational Hurdles: Even if a country suspects sabotage, gathering and publicizing irrefutable evidence can be diplomatically and legally fraught, especially in disputed or international waters.
Key Takeaways
- Confirmed Sabotage vs. Suspicion: Incidents in the Baltic (Nord Stream pipelines, reported cable damage) highlight the real possibility of state actors targeting undersea infrastructure. However, public, conclusive proof of exactly who carried out each incident remains limited or contested.
- Taiwan Incidents: While there is evidence that Chinese vessels were involved in damaging cables near Taiwan’s Matsu Islands, it is not definitively established that these were intentional acts of sabotage. Nonetheless, the incidents have raised legitimate concern about how easily Taiwan’s communications links could be disrupted—whether accidentally or deliberately.
- Strategic Vulnerability: Undersea cables (and pipelines) are indeed an attractive target in any “shadow war” scenario. Their disruption can yield outsized consequences due to how critical they are to global finance, internet access, and military coordination.
Ultimately, while it is accurate to say there have been suspicious or outright damaging incidents involving pipelines and cables in the Baltic and off Taiwan, the leap to a confirmed global campaign of deliberate cable-cutting—especially attributing it to specific nations—warrants caution. What is clear, though, is that states are increasingly aware of (and concerned about) the strategic leverage these underwater chokepoints represent and NATO navies are paying close attention!
the information below represents a synthesis of what has been widely discussed lately, in open reporting and strategic analyses.
1. The Strategic Importance of Baltic Sea Cables
- Data Backbone: Over 95% of global internet, voice, and data traffic travels via undersea cables. An estimated US$10 trillion or more in financial transactions moves across these cables daily.
- European Connectivity: The Baltic Sea is crisscrossed by critical cables linking Northern European countries (Sweden, Finland, Estonia, Latvia, etc.) both to each other and to the wider global network. Disruptions there can cause significant economic and communications fallout.
- Recent Focus: Over the past few years, the Nord Stream pipeline sabotage (September 2022), damage to a Finland-Estonia gas pipeline and communications cable (October 2023), and now alleged cable breaks between Sweden and its neighbors have drawn heightened attention to potential hostile activity under the Baltic.
2. Growing Concerns About Russian Sabotage
- Post–Nord Stream Anxiety: While the September 2022 Nord Stream explosions (involving the Nord Stream 1 and 2 gas pipelines) remain officially unsolved, many Western officials suspect a state actor’s involvement. This incident highlighted how vulnerable undersea infrastructure can be to sabotage.
- Pattern of Suspicious Activity: Various European defense analysts and intelligence agencies have pointed to an uptick in Russian naval and “research” vessel presence near critical undersea routes—though direct evidence tying those vessels to sabotage remains largely classified or circumstantial.
- Accidents vs. Deliberate Action: Cables and pipelines do sometimes get damaged by fishing nets, anchors, or natural events. However, the frequency and timing of recent incidents have fueled suspicions that some are deliberate.
3. NATO’s Response: The “Baltic Sentry” Mission
- Enhanced Monitoring: NATO has been steadily increasing its maritime patrols and surveillance across the Baltic Sea region, especially after multiple undersea incidents.
- Baltic Sentry: While NATO has a range of standing naval forces and maritime missions (e.g., Standing NATO Maritime Groups), reports suggest a more focused initiative—referred to by some as the “Baltic Sentry” mission—has been launched to coordinate intelligence-sharing, patrols, and rapid-response capabilities specifically aimed at safeguarding undersea cables and pipelines.
- Note: Official NATO communications sometimes use different names or do not disclose detailed operational codenames. “Baltic Sentry” may be an umbrella term used in media/analyst circles, or an internal working name for a bolstered presence in the region.
4. The 2024 Incidents and Cable Breaks
- Multiple Cable Damages: In 2024, a series of incidents saw several undersea data cables in the Baltic either severely damaged or severed outright. Sweden, Finland, Estonia, and Latvia each reported unexpected outages.
- Attribution Theories: Western defense officials have repeatedly pointed to Russia-backed vessels or pro-Russian “private” actors as prime suspects, though public “smoking gun” evidence can be sparse.
- Motives: Sabotaging cables can:
- Undermine civilian and military communications.
- Generate economic disruption.
- Send a geopolitical signal of capability to strike “behind the scenes.”
5. Sweden’s Seizure of Suspected Vessel
- Incident Summary: On a recent Sunday (as reported), Swedish authorities seized a ship suspected of damaging a data cable linking Sweden to Latvia.
- What We Know
- Location: The cable break occurred in Swedish territorial (or near-territorial) waters of the Baltic Sea.
- Suspicious Activity: Local media quoted Swedish coast guard or navy sources who believed the vessel may have been operating with specialized equipment or atypical patterns (e.g., suspicious anchoring or trawling) that led to the cable’s severance.
- Legal Grounds for Seizure: Under maritime law, Sweden has the right to detain vessels within its territory if there is probable cause that they have caused serious harm or pose an immediate threat to critical infrastructure or environment.
- Possible Outcomes:
- If evidence confirms intentional sabotage, it could lead to diplomatic escalation or even charges under Swedish law.
- If deemed accidental, the vessel’s owners/operators may face civil or financial penalties but not necessarily criminal charges.
- Ongoing forensic analysis of damage to the cable—and any specialized equipment found on board—will be central to clarifying whether sabotage was intended.
6. Wider Implications
- Security and Deterrence: The Swedish seizure indicates Baltic nations are shifting from passive monitoring to proactive interdiction when they see signs of infrastructure tampering. This raises the deterrent for would-be saboteurs.
- NATO Cohesion: Events like this underscore the importance of intelligence-sharing among NATO allies, rapid response units, and possibly new frameworks for joint maritime policing under missions like “Baltic Sentry.”
- Hybrid Warfare Fears: Damaging critical infrastructure is a classic “hybrid” or “gray zone” tactic—covert enough to allow plausible deniability but impactful enough to disrupt or intimidate an adversary. This complicates direct attribution and can escalate tensions without open conflict.
- Commercial Collaboration: The majority of undersea cable infrastructure is owned or co-owned by private telecommunications consortia. Governments, navies, and private companies must coordinate heavily to maintain real-time situational awareness of any anomalies along cable routes.
In Summary
- Mounting Tensions in the Baltic: A series of undersea cable breaks in 2024 raised alarm among NATO members, prompting a stepped-up maritime security initiative often referred to as “Baltic Sentry.”
- Swedish Intervention: Swedish authorities’ recent action—seizing a vessel suspected of deliberate or negligent cable damage—signals a more assertive stance in protecting critical data links.
- Uncertain Attribution: While many Western analysts and officials suspect Russian involvement in these incidents, definitive public evidence remains limited. Official investigations and intelligence might clarify whether these are state-sponsored acts of sabotage or “accidents” that coincide suspiciously with geopolitical tensions.
- High Stakes: Given the immense strategic and economic value of undersea cables, protecting them has become a top priority for navies and governments worldwide—particularly in the Baltic, where tensions between NATO and Russia remain high.
