Introduction: Europe’s Most Vulnerable Front May Be Beneath the Water
Europe is discovering that modern security is no longer defined only by tanks crossing borders or fighter jets entering airspace. Some of the most strategically important battles could begin far below the surface, around ports, pipelines, offshore energy facilities and the undersea cables that quietly carry the continent’s digital life.
The European Union is therefore moving toward a broader concept of maritime defence—one that combines warships, surveillance, cybersecurity, infrastructure protection and industrial capacity. The shift reflects a hard lesson from recent years: an attack does not necessarily need to look like a conventional military strike to cause enormous economic damage.
Around 90% of the EU’s external freight trade is transported by sea, while undersea cables carry virtually all intercontinental internet traffic. That dependence makes European waters a critical strategic space.
Against this backdrop, defence spending across the EU has accelerated dramatically. European Defence Agency data shows that the 27 EU member states spent €343 billion in 2024, equivalent to roughly $400 billion, an increase of 19% from the previous year. The agency estimated that 2025 spending could reach €392 billion, or about $457 billion, at current prices.
The money is not simply going toward traditional armies. Increasingly, it is supporting naval capabilities, maritime surveillance, critical-infrastructure protection and a European defence industry intended to become faster, larger and less dependent on foreign suppliers.
The Sea Is Europe’s Economic Lifeline
Trade Depends on Open Water
Europe’s economy is deeply connected to maritime transport. Ports are gateways for energy, food, raw materials, manufactured products and consumer goods. The European Commission describes maritime transport as a central vehicle for Europe’s imports and exports, with almost 90% of the EU’s external freight trade moving by sea.
That percentage explains why maritime security has become an economic issue rather than merely a military one.
A serious disruption at major European ports could affect factories thousands of kilometres away. A prolonged interruption to shipping lanes could increase energy and commodity prices. Damage to critical infrastructure could create consequences extending far beyond the original attack site.
The Invisible Digital Dependency
The maritime vulnerability goes even deeper.
Modern Europe depends on a vast network of submarine communications cables. These systems carry internet traffic, financial transactions, cloud services, government communications and corporate data between continents.
The European Parliament has highlighted that roughly 99% of intercontinental internet traffic is carried through undersea cables.
This creates an unusual security problem: a cable may be physically located underwater, but its failure can have consequences across the digital economy.
The result is a new security equation in which a vessel, submarine, anchor, remotely operated system or deliberate act of sabotage could potentially become part of a much larger geopolitical crisis.
Hybrid Warfare Has Changed the Maritime Threat
The New Battlefield Is Not Always Obvious
Europe’s maritime security concerns are increasingly shaped by what is commonly called hybrid warfare.
Instead of relying exclusively on conventional military attacks, hostile actors can combine cyber operations, espionage, disinformation, economic pressure, sabotage, covert activity and military signalling.
This makes attribution difficult.
A damaged cable does not automatically prove sabotage. A cyberattack does not necessarily reveal who ordered it. An unidentified vessel operating near sensitive infrastructure may be conducting routine activity—or something much more deliberate.
That uncertainty itself can become a strategic weapon.
Russia Remains a Central Concern
The deterioration of Europe’s security environment since Russia’s full-scale invasion of Ukraine has accelerated defence planning across the continent.
EU institutions have repeatedly linked the expansion of European defence capabilities to the changing geopolitical environment and Russia’s aggression against Ukraine.
Maritime security fits directly into this wider picture because Russia possesses significant naval, submarine, intelligence and electronic-warfare capabilities.
For Europe, the concern is therefore not limited to a conventional naval confrontation. It also includes the protection of infrastructure that may be difficult to defend continuously and almost impossible to monitor perfectly.
Europe’s Defence Spending Has Entered a New Era
From €343 Billion to a Projected €392 Billion
The scale of
According to the European Defence Agency, EU member states spent €343 billion in 2024—approximately $400 billion at the ECB’s August 25 reference rate of €1 = $1.1662. Defence spending increased 19% year over year.
For 2025, EDA data projected spending at €392 billion, approximately $457 billion, at current prices. The same source also gives a constant-2024-price estimate of €381 billion, showing why different reports sometimes cite different 2025 figures.
This distinction matters.
A headline saying Europe “spent $457 billion” can imply a final audited figure when €392 billion was a current-price estimate. Responsible reporting should make that distinction clear.
Equipment Procurement Is Accelerating
The transformation is also visible in procurement.
The European Defence Agency reported that defence equipment procurement reached €88 billion in 2024, an increase of 39% from 2023.
That means
Ships, aircraft, air-defence systems, missiles, drones, sensors, communications equipment and electronic-warfare systems are all competing for a larger share of national defence budgets.
For maritime security, that trend is particularly significant.
SAFE Gives Europe a Major New Financial Tool
The $175 Billion Defence Loan Instrument
The EU’s Security Action for Europe, known as SAFE, represents one of the most important financial mechanisms behind Europe’s defence buildup.
SAFE provides up to €150 billion in loans—approximately $175 billion at the August 25, 2026 ECB reference rate—to support rapid increases in defence investment and common procurement.
SAFE is not simply a giant cash grant.
The money is provided through long-maturity loans that beneficiary member states must repay. The system is designed to encourage countries to purchase capabilities together rather than independently duplicating the same systems.
That distinction is strategically important.
If European countries use SAFE effectively, the result could be more common equipment, greater interoperability and larger production runs for European manufacturers.
If they use the money primarily through fragmented national programmes, Europe could spend enormous amounts while continuing to operate a patchwork of incompatible systems.
Why Shipbuilding Is Becoming Strategically Important
Warships Are Only One Part of the Equation
A stronger maritime defence strategy naturally creates demand for ships.
But the real requirement is broader than simply building more frigates or patrol vessels.
Europe needs platforms capable of persistent surveillance, anti-submarine warfare, air defence, mine countermeasures, intelligence gathering, electronic warfare and protection of maritime infrastructure.
Some missions may also require smaller vessels, unmanned systems and autonomous underwater vehicles rather than traditional warships.
This means the future European fleet may be considerably more technologically diverse than the fleets of previous decades.
Europe Needs More Than Hulls
A ship is not useful simply because it exists.
Modern naval power depends on radar, sonar, secure communications, electronic warfare, weapons, software, satellites, logistics and trained crews.
The industrial challenge is therefore much larger than shipyard capacity.
Europe needs an ecosystem capable of producing and maintaining the complete maritime defence architecture.
The European Patrol Corvette Shows the Direction
A More Integrated European Naval Industry
One of the clearest examples of European cooperation is the European Patrol Corvette programme.
The project brings together major European shipbuilding groups including Naval Group, Fincantieri and Navantia, with Naviris coordinating industrial cooperation. The programme is designed around a next-generation modular patrol vessel intended to serve multiple European naval requirements.
The first phase of the programme had a value of €87 million, approximately $101.5 million, with €60 million supported by the European Commission and the remainder funded by participating member states.
The project illustrates a larger European ambition: build common platforms rather than forcing every country to develop its own completely independent solution.
Cooperation Could Reduce Europe’s Fragmentation
European defence has historically suffered from fragmentation.
Different countries have purchased different ships, aircraft, weapons, communication systems and logistics platforms.
That can make joint operations more complicated and increase long-term maintenance costs.
A common naval programme can potentially reduce duplication while creating economies of scale.
The European Patrol Corvette is therefore important not only because of the ships it may eventually produce, but because it represents an attempt to change how Europe designs and purchases military equipment.
France, Germany, Italy and Spain Remain Industrial Heavyweights
Europe’s Naval Production Is Concentrated
The original report highlights France, Germany, Italy and Spain as dominant contributors to European naval production.
This concentration is understandable.
France has Naval Group and a long-established naval construction ecosystem. Italy is home to Fincantieri, one of Europe’s largest shipbuilding companies. Spain has Navantia, while Germany has a major naval industrial base including Thyssenkrupp Marine Systems.
These countries possess decades of engineering experience, shipyard infrastructure and relationships with domestic and international navies.
Export Markets Matter Too
European naval companies are not relying exclusively on domestic demand.
Major European shipbuilders compete aggressively in international markets, where export contracts can help sustain production lines, engineering teams and supply chains.
This creates a feedback loop.
More domestic orders can preserve industrial capacity. Stronger industrial capacity can improve export competitiveness. Export success can then support additional investment in research, production and workforce development.
Maritime Defence Is Becoming a Cybersecurity Problem
Ships Are Now Floating Computer Networks
A modern warship is effectively a highly complex network with engines attached.
Its sensors, navigation systems, communications equipment, weapons, logistics and mission systems depend heavily on software.
That makes cybersecurity inseparable from maritime defence.
A sophisticated cyberattack does not necessarily need to sink a ship to create damage. Disrupting communications, navigation, logistics or command systems could reduce operational effectiveness at critical moments.
Ports Are Equally Exposed
Ports face similar risks.
Modern ports rely on automated cranes, logistics software, customs systems, scheduling platforms, industrial control systems and interconnected supply-chain networks.
A cyberattack against a major port could therefore create disruption without a single physical explosion.
This is one reason European maritime defence increasingly overlaps with cybersecurity.
Undersea Infrastructure May Become the Next Major Security Priority
Cables Are Difficult to Defend
There are thousands of kilometres of underwater cables supporting Europe’s digital economy.
The physical geography makes them extremely difficult to monitor continuously.
Unlike a military base, a cable does not have a fence, guard tower or obvious perimeter.
A future maritime-security strategy may therefore increasingly depend on combinations of seabed mapping, acoustic sensors, satellite surveillance, patrol aircraft, naval vessels, autonomous underwater vehicles and artificial intelligence.
Detection Could Matter More Than Retaliation
The most valuable capability may not always be the ability to respond after damage occurs.
It may be the ability to identify suspicious activity early.
If authorities can detect unusual vessel movements, underwater activity or electronic signals before critical infrastructure is damaged, governments gain more options.
Early warning could turn a potential crisis into a manageable security incident.
Europe’s Maritime Strategy Is Becoming Multi-Layered
The Surface Layer
At the surface, Europe needs patrol vessels, frigates, coast guards and surveillance aircraft capable of monitoring maritime traffic.
These assets provide the visible layer of protection.
The Subsurface Layer
Below the surface, the challenge becomes more complicated.
Submarine activity, autonomous underwater vehicles, seabed infrastructure and undersea cables require specialised sensors and monitoring capabilities.
This is where conventional naval power intersects with emerging technology.
The Digital Layer
Above both sits the digital layer.
Ports, ships, naval bases, logistics networks and infrastructure operators are connected through increasingly complex information systems.
A maritime defence strategy that ignores cybersecurity would therefore leave a major weakness exposed.
Europe’s Biggest Challenge May Be Coordination
Spending More Does Not Automatically Create More Security
This is perhaps the most important lesson behind the spending boom.
Europe can spend hundreds of billions of dollars on defence and still have vulnerabilities if procurement remains fragmented.
A country can have an advanced frigate while another operates incompatible communications equipment.
One navy may possess excellent sensors while another lacks the infrastructure needed to share information with it.
Defence spending must therefore be measured not only by how much money is allocated but by what capabilities emerge from that money.
Interoperability Will Determine the Return on Investment
The ability of European forces to communicate, share intelligence and operate together will become increasingly important.
This is especially true in maritime security, where an incident can move rapidly across national waters and economic zones.
A suspicious vessel near one country may be approaching infrastructure belonging to another.
A cyberattack on one port may spread through a shared logistics provider.
A damaged cable may affect multiple countries simultaneously.
These are problems that do not respect national borders.
Deep Analysis: Commands for Europe’s Maritime Defence
Command 1: Protect the Infrastructure First
Europe should treat undersea cables, energy pipelines, offshore installations and major ports as strategic infrastructure rather than purely commercial assets.
Their protection should be integrated into national and EU security planning.
Command 2: Build a Permanent Maritime Surveillance Network
Europe needs persistent surveillance rather than occasional patrols.
Satellites, aircraft, ships, coastal sensors and autonomous systems should feed into a common operational picture.
Command 3: Expand Underwater Monitoring
The seabed should become a much higher priority for European security investment.
Autonomous underwater vehicles, seabed sensors and acoustic monitoring could help identify suspicious activity around critical infrastructure.
Command 4: Connect Cybersecurity With Naval Operations
Cybersecurity teams should not operate separately from maritime defence planners.
The security of ports, ships, naval bases and logistics systems should be considered part of one interconnected environment.
Command 5: Make SAFE Procurement Truly European
The SAFE mechanism should encourage joint purchasing and European industrial cooperation whenever doing so produces genuine strategic benefits.
The objective should not simply be to spend faster.
The objective should be to build stronger capabilities.
Command 6: Reduce Procurement Fragmentation
Europe should avoid creating dozens of separate solutions to the same problem.
Common standards, shared platforms and compatible technologies can make European defence more efficient.
Command 7: Invest in Smaller Autonomous Systems
Europe does not need to answer every maritime threat with a large warship.
Unmanned surface vessels, underwater drones and autonomous surveillance systems could provide persistent monitoring at lower operating costs.
Command 8: Strengthen Civilian-Military Cooperation
Commercial shipping companies, telecom operators, energy companies and port authorities possess information that military organisations may not have.
A stronger security model should create mechanisms for responsibly sharing relevant information.
Command 9: Build Resilience Instead of Assuming Perfect Protection
Europe cannot realistically protect every metre of cable or pipeline.
It must therefore combine physical protection with redundancy.
Alternative cable routes, backup communications, spare equipment and rapid-repair capabilities can reduce the consequences of successful attacks.
Command 10: Measure Results, Not Headlines
The success of
How quickly can a suspicious vessel be identified?
How quickly can a damaged cable be repaired?
How quickly can a cyberattack be contained?
How effectively can multiple European navies operate together?
Those questions are more important than the size of a defence budget headline.
What Undercode Say:
Europe Is Finally Treating the Sea as a Strategic Battlefield
The most important development is not simply that European governments are spending more money.
It is that the definition of maritime security is expanding.
Europe increasingly understands that its ports, cables, energy systems and shipping lanes are interconnected.
The Undersea Domain Deserves More Attention
The seabed could become one of the most strategically important environments of the coming decade.
It contains infrastructure essential to communications and energy, yet remains difficult to monitor.
That combination makes it particularly attractive to actors seeking asymmetric advantages.
Naval Power Is Returning to European Strategy
For decades, European defence debates were dominated by land and air capabilities.
The changing security environment is forcing maritime power back toward the centre of strategic planning.
More Ships Are Not Automatically the Answer
A larger fleet can help, but ships alone cannot solve Europe’s maritime-security problem.
Europe also needs sensors, satellites, cyber defence, autonomous systems, intelligence and resilient infrastructure.
The Industrial Dimension May Be Just as Important
A credible maritime strategy requires a credible industrial base.
If European countries cannot produce ships, engines, sensors, weapons and software at scale, their strategic ambitions will remain dependent on external suppliers.
SAFE Could Change Procurement
The €150 billion SAFE instrument—roughly $175 billion—could become a major driver of European defence-industrial cooperation.
But its ultimate value will depend on how efficiently countries use it.
Europe Has a Historic Opportunity
The current defence buildup gives European governments an opportunity to fix longstanding industrial weaknesses.
They can either purchase equipment separately and preserve fragmentation, or use the spending surge to create a more integrated defence ecosystem.
The Shipbuilding Sector Could Become a Strategic Asset
European shipyards are not merely manufacturers.
They represent engineering knowledge, skilled employment, supply chains and strategic independence.
Maintaining that industrial capacity could become increasingly important during a prolonged geopolitical confrontation.
The Biggest Risk Is Fragmentation
Europe’s greatest weakness may not be a lack of money.
It may be the inefficient use of money.
If dozens of countries pursue incompatible systems, the continent could spend more while gaining less.
Maritime Security Will Become More Technological
The future maritime battlefield will involve artificial intelligence, autonomous vehicles, satellites, electronic warfare, cyber operations and real-time data analysis.
Traditional naval platforms will remain important, but they will increasingly operate as nodes inside a larger network.
Ports Will Become Cybersecurity Targets
The security of a port can no longer be separated from the security of its computer networks.
A cyberattack can disrupt physical commerce without physically damaging infrastructure.
Undersea Cables Will Receive Greater Political Attention
The growing recognition of cable vulnerability will likely lead to more monitoring, redundancy and international cooperation.
Europe Needs Faster Repair Capabilities
Protection is only one side of resilience.
When infrastructure is damaged, the ability to repair it rapidly can determine whether an incident becomes a crisis.
Intelligence Sharing Will Become Essential
Maritime threats frequently cross borders.
European countries will therefore need stronger mechanisms for sharing information about vessels, suspicious behaviour, cyber incidents and infrastructure risks.
Autonomous Surveillance Could Be a Major Force Multiplier
Unmanned systems could allow Europe to monitor large maritime areas without requiring expensive crewed platforms to remain permanently on station.
Artificial Intelligence Could Transform Maritime Awareness
AI systems could process vessel movements, satellite imagery, sensor data and historical patterns to identify anomalies that humans might overlook.
But AI Cannot Replace Human Judgment
False positives could generate unnecessary confrontations.
Maritime surveillance therefore needs human oversight, transparent procedures and reliable intelligence verification.
Europe Is Building a Deterrence Architecture
The goal is not necessarily to fight a maritime war.
The objective is to make hostile action more difficult, more visible and more costly.
Deterrence Depends on Credibility
A strategy works only if potential adversaries believe Europe has the capability and political will to respond.
That requires more than announcements.
It requires functioning equipment, trained personnel and coordinated command structures.
The Mediterranean Matters Too
European maritime security is not limited to the North Sea and Baltic.
The Mediterranean remains strategically important for energy, migration, trade and connections with the Middle East and North Africa.
The Atlantic Dimension Cannot Be Ignored
Europe’s economic connection to North America depends heavily on maritime and digital infrastructure crossing the Atlantic.
Transatlantic resilience is therefore directly connected to European security.
Energy Security Is Maritime Security
Europe’s energy transition does not eliminate maritime vulnerability.
Liquefied natural gas, offshore wind infrastructure, electricity connections and other energy systems all create new security requirements.
Defence Spending Is Becoming Industrial Policy
The European defence buildup is increasingly intertwined with manufacturing policy.
Governments want not only stronger militaries but also stronger domestic industries.
That Could Create Economic Benefits
Defence investment can support engineering, manufacturing, research and skilled employment.
But those benefits depend on long-term industrial planning rather than short-term procurement surges.
Export Success Will Matter
If European companies can compete internationally, domestic investment can produce broader industrial benefits.
European Cooperation Could Increase Global Competitiveness
Joint programmes can give European manufacturers larger production volumes and stronger international offerings.
Yet Cooperation Will Not Be Easy
National industrial interests remain powerful.
Governments naturally want contracts and jobs to remain within their own borders.
Political Compromise Will Shape the Outcome
The technical solution may be obvious while the political solution remains difficult.
Europe’s defence transformation will therefore depend as much on coordination as engineering.
The 2020s Could Become a Turning Point
The continent has moved from years of relatively restrained defence spending toward a period of rapid military investment.
That change is unlikely to disappear quickly.
Maritime Security Could Become a Permanent Priority
Even if geopolitical tensions eventually decline, the dependence on digital infrastructure and global shipping will remain.
The underlying vulnerability will not disappear.
Europe Is Learning From Recent Incidents
The growing concern surrounding critical infrastructure has demonstrated that security cannot be measured only by conventional military threats.
The Future Battlefield Will Be Everywhere
The distinction between land, sea, air, space and cyberspace is becoming increasingly blurred.
A single incident could involve several of these domains simultaneously.
The Real Test Will Be Execution
Europe now has more money, more political urgency and more industrial ambition.
The decisive question is whether it can transform those resources into coordinated capabilities.
The Maritime Shield Is Only Beginning
Europe’s new maritime strategy is not simply about buying more ships.
It is about creating a security ecosystem capable of protecting the physical and digital foundations of European prosperity.
Spending Figures
✅ The €343 billion figure for 2024 and the 19% year-on-year increase are supported by European Defence Agency data. The agency also projected €392 billion for 2025 at current prices, while another official presentation uses €381 billion in constant 2024 prices.
SAFE Funding
✅ SAFE provides up to €150 billion in EU loans for defence investment and common procurement. Converted at approximately €1 = $1.1662, that is about $175 billion. It is a loan instrument rather than a direct €150 billion grant.
Maritime Trade Dependency
✅ The statement that roughly 90% of EU external freight trade is transported by sea is supported by the European Commission. The broader claim that “90% of EU trade, energy supplies and internet data move by sea” is too broad as written and combines different statistics that should be separated.
Prediction
(+1) Europe Will Continue Expanding Maritime Security
European maritime defence spending is likely to remain elevated because the underlying vulnerabilities—shipping dependence, undersea cables, energy infrastructure and geopolitical competition—are structural rather than temporary.
(+1) Undersea Surveillance Will Become a Major Investment Area
Expect greater attention to seabed monitoring, autonomous underwater systems, cable protection and rapid-repair capabilities as European governments attempt to reduce their exposure to infrastructure disruption.
(+1) Joint Procurement Will Become More Important
The combination of SAFE, Readiness 2030 and growing defence budgets should push European countries toward more multinational procurement programmes, particularly where common platforms can reduce costs and improve interoperability.
(+1) European Naval Industry Could Enter a Long Expansion Cycle
If current defence commitments continue, major shipbuilders and their supply chains are likely to benefit from sustained demand for patrol vessels, frigates, submarines, support ships, autonomous systems and maritime sensors.
(-1) Fragmentation Could Limit the Results
The biggest threat to Europe’s defence transformation may be inefficient procurement. If national governments prioritise domestic preferences over interoperability and shared platforms, Europe could spend enormous sums without achieving proportional improvements in collective security.
(+1) The Definition of Maritime Defence Will Keep Expanding
The future European maritime-security model is likely to combine warships with cyber defence, satellites, autonomous vehicles, intelligence networks and infrastructure resilience. The strongest maritime shield will not be a fleet alone—it will be an interconnected system.
