European Governments' Critical Dependencies on US Electronics: Medium-Term Challenges

While Europe faces significant medium-term constraints in achieving electronic independence from US systems, there are pathways to gradually reducing dependencies. The European Commission's "ReArm Europe" plan aims to unlock up to €800 billion for defense, including investment in domestic capabilities[10]. The focus on developing strategic enablers represents a logical starting point, targeting systems that would be necessary to deter or fight without US support.

All key enablers are not in American hands - such as AWACs allocated to NATO and some French assets, present and future.

However, complete independence remains unlikely in the medium term. The deeply integrated nature of transatlantic defense cooperation, combined with the technical challenges of developing advanced electronic systems, ensures that some level of dependency will persist. As one expert noted, Europe "cannot simply switch off its dependencies on America" but can "take steps to manage the risks"[10]. The most realistic path forward combines targeted investment in critical capabilities with strategic management of remaining dependencies.

European Governments' Critical Dependencies on US Electronics: Medium-Term Challenges

Europe faces significant challenges in reducing its reliance on US electronics technologies, particularly in strategic sectors. While European leaders increasingly call for technological sovereignty, several critical dependencies on American electronic systems cannot be easily replaced within the medium term (3-5 years). This analysis examines the entrenched dependencies in defense, communications, and industrial applications that will require sustained effort and substantial investment to overcome.

 Defense Electronics and Strategic Enablers

European defense capabilities are heavily dependent on US electronics systems, creating vulnerabilities that cannot be quickly addressed. This dependency extends beyond mere procurement patterns to operational capabilities that are deeply embedded in European military structures.

 Critical Military Systems Integration

European militaries are fundamentally structured around interoperability with US armed forces, creating dependencies that extend to the core of their operational capabilities[10]. Almost two-thirds of arms imported by European NATO members between 2020-2024 came from the US, an increase from 52% in the previous five-year period[7]. This dependency is particularly pronounced in certain countries - over 90% of arms imports in Norway, Sweden, Italy, and the Netherlands came from the US, while the UK figure exceeded 80%[7].

The most challenging area to replace is what experts call "strategic enablers" - the critical systems that make modern warfare possible. These include:

- Satellite communications infrastructure
- Intelligence and surveillance systems
- Theater protection capabilities
- Electronic warfare countermeasures
- Secure communications networks[10]

As one defense specialist noted, "If you talk about tanks and these kinds of things, the gap between the US and EU is probably not so big. However for the strategic enablers, a lot comes from the US such as transport helicopters or satellite communications. We are very dependent on the infrastructure as well as on the products"[7].

 The F-35 Dependency Model

Perhaps no system better exemplifies Europe's electronic dependency than the F-35 fighter jet. This fifth-generation combat aircraft, with 150 units currently operated by non-US NATO allies, demonstrates how hardware dependency extends to ongoing operational dependence[10]. The F-35 relies on:

- Constant data integration from US systems
- Regular software updates controlled by the US
- Maintenance systems tied to US infrastructure

This creates an operational vulnerability that cannot be quickly resolved. If Washington chose to, "it could make it hard if not impossible for these jets to fly"[10], giving the US significant leverage over European defense capabilities.

 Semiconductor and Electronics Manufacturing Constraints

The hardware foundations of Europe's technological sovereignty face serious challenges in achieving independence from US systems.

 Declining Manufacturing Base

European electronics manufacturing capacity has dramatically declined over recent decades:
- Europe's share of global printed circuit board (PCB) production has plummeted from 13.8% to merely 2.2%[6]
- The EU's dependency on non-EU PCBs across strategic sectors is expected to increase from 82.5% in 2023 to 88.9% by 2035[6]
- Only 8% of global defense-related advanced packaging production occurs in the EU[4]
- Just 6% of global defense-related PCBs are produced in Europe, with the industry "at a critical juncture with a risk of disappearing entirely from the region"[4]
- A mere 4% of global defense-related IC substrate production takes place in the EU[4]

The electronics component in defense equipment is growing rapidly - from 10% of equipment value in 2000 to 17% today, and projected to reach 25% by 2035-2040[4]. This creates a widening gap between European needs and production capabilities that will be difficult to close.

 Semiconductor Ecosystem Limitations

While Europe has made efforts to boost its semiconductor industry through initiatives like the European Chips Act[5], its position in the global ecosystem remains limited:

- Europe accounts for just 10% of the global microchips market[11]
- The region remains dependent on a complex global supply chain for advanced chip design and manufacturing
- Critical components of the semiconductor ecosystem, such as design tools and advanced manufacturing equipment, remain dominated by US companies[13]

 Digital Infrastructure Dependencies

Beyond hardware components, European digital sovereignty faces significant challenges in cloud computing and data infrastructure.

 Cloud Computing Dominance

European digital infrastructure relies heavily on US-based services:
- American companies like Amazon, Microsoft, and Google control over two-thirds of the European cloud market[11]
- This creates dependencies not just for commercial applications but for government services and defense systems
- The infrastructure required to replace these services would require not just financial resources but significant time to develop

 AI Systems and Advanced Software

The software layer creates another dimension of dependency:
- US-based companies like OpenAI and Anthropic lead in artificial intelligence development[11]
- AI capabilities are increasingly central to both civilian and military applications
- The data and expertise required to develop competitive AI systems represents a significant hurdle for European independence

 Temporal and Structural Obstacles to Autonomy

Even with political will and financial resources, Europe faces significant challenges in achieving electronic independence within the medium term.

 Realistic Timeframes for Capability Development

Experts provide clear assessments of the timeline required to reduce dependencies:
- "In three years, it's going to be very difficult for Europe to be ready on its own," though "in five years, it's a different ball game"[7]
- For complex products, development typically requires "two, three years" even in normal circumstances, with time pressures providing only limited acceleration opportunities[7]
- According to defense experts, Europe could achieve self-sufficiency within five years in selected areas like battlefield command and control, long-range strikes, and suppression of enemy air defenses[10]
- However, other critical capabilities, particularly space-based intelligence systems, will require substantially more time[10]

 Supply Chain Entanglement

The interdependent nature of defense industrial production creates additional obstacles:
- Many defense products are "truly NATO products built with components from many allies"[7]
- The F-35, while American-designed, incorporates components and expertise from multiple European countries[7]
- This integration makes "European" and "American" distinctions somewhat artificial in many complex systems

 Conclusion: Pathways to Reduced Dependency

While Europe faces significant medium-term constraints in achieving electronic independence from US systems, there are pathways to gradually reducing dependencies. The European Commission's "ReArm Europe" plan aims to unlock up to €800 billion for defense, including investment in domestic capabilities[10]. The focus on developing strategic enablers represents a logical starting point, targeting systems that would be necessary to deter or fight without US support.

However, complete independence remains unlikely in the medium term. The deeply integrated nature of transatlantic defense cooperation, combined with the technical challenges of developing advanced electronic systems, ensures that some level of dependency will persist. As one expert noted, Europe "cannot simply switch off its dependencies on America" but can "take steps to manage the risks"[10]. The most realistic path forward combines targeted investment in critical capabilities with strategic management of remaining dependencies.
