Europe’s reliance on maritime trade routes presents a critical security vulnerability that outweighs traditional land-based threats, according to Tarmo Soomere, a coastal engineering professor at Tallinn University of Technology and a representative at the NATO Science and Technology Organization. While Central and Eastern Europe have fortified land and air defenses, the continent’s economic stability remains tethered to global shipping lanes that are increasingly susceptible to low-cost, disruptive technologies like autonomous underwater drones.
Why is Europe’s maritime infrastructure at risk?
Over 80% of global trade travels by sea, making maritime supply chains the continent’s most vital, yet least protected, artery. Tarmo Soomere notes that European nations have failed to fully internalize the systemic fragility exposed by events like the 2021 Suez Canal blockage. Stéphane Audrand, a researcher at the Groupe d’études géopolitiques in Paris, argues that the outdated perception of threats arriving solely from the East ignores the reality that Europe functions as a peninsula dependent on maritime connectivity. The vulnerability is not merely a matter of large-scale naval warfare; it is the potential for small-scale, hard-to-detect drone attacks to paralyze financial markets and insurance sectors.
The “shadow fleet”—a network of tankers and vessels operating outside standard regulatory frameworks—has become a primary vehicle for transporting not just oil, but potentially autonomous hardware capable of disrupting critical subsea infrastructure.
Could a 2032 scenario lead to economic collapse?
A geopolitical thought experiment developed by Stéphane Audrand illustrates how a conflict could shift from a land-based defense to a maritime catastrophe. In this scenario, even if NATO successfully repels a conventional land offensive in the Baltic states, Russia could pivot to subsea sabotage. By deploying autonomous underwater vehicles against wind farms in the North Sea and targeting merchant vessels, an aggressor could force insurance premiums to spike, causing shipowners to withdraw from European waters. This “gray zone” warfare creates a domino effect: energy shortages, severed subsea data cables, and the isolation of landlocked Central European nations.
The challenge of the “underwater” domain
Control of the sea surface and airspace does not guarantee security in the deep-water domain. According to Soomere, Russian drones and submarines operate with low acoustic signatures, making them difficult to track. While the West maintains superior conventional naval power, protecting thousands of miles of subsea infrastructure against cheap, mass-produced drones creates an unsustainable resource drain. The logistical burden of organizing convoy systems, similar to those used in the Second World War, would likely deplete the remaining naval resources needed for active defense.
How does the maritime industry’s structure hinder defense?
Maritime security is complicated by the fragmented nature of the global shipping industry. Vessels are often built in Asia, owned by private entities in tax havens, and crewed by third-party nationals. Because these ships frequently sail under “flags of convenience,” they lack a direct patriotic mandate to support European defense efforts. This economic reality means that during a crisis, private shipping companies are more likely to prioritize asset preservation over national security, leading to the rapid disintegration of supply chains.

Frequently Asked Questions
- Why are subsea cables a target?
Subsea cables carry the vast majority of global internet traffic and financial data. Their destruction causes immediate, cascading failures in IT systems and financial markets. - Are wind farms considered military targets?
Yes. In a modern conflict, critical energy infrastructure like offshore wind farms are “soft targets” that, if disabled, cause immediate power instability and economic panic. - Can NATO protect every ship?
No. The sheer volume of global maritime trade makes comprehensive escorting impossible, especially when faced with asymmetric threats like autonomous drones.
