Ukraine Starlink reliance: Why Europe is racing to build Iris²

Why does Ukraine rely so heavily on Starlink?

Ukraine relies on Starlink for real-time battlefield communications and Starshield, a US-government-controlled service, for high-stakes military operations such as drone warfare. The network provides the high-speed, low-latency connectivity required to pilot unmanned vehicles and intercept Russian attacks in real-time. According to Vincent Tourret, a researcher at the French Institute of International Relations, high-speed internet is a prerequisite for modern drone warfare.

The technical superiority of the SpaceX constellation is evident in both speed and hardware portability. Starlink terminals are lightweight and compact, allowing them to be mounted on small drones or various mobile vehicles. In contrast, competitors often require larger equipment that is better suited for vehicle roofs than for agile tactical units.

The tactical advantage of latency

In modern combat, the speed of data transfer can determine the outcome of an engagement. Soldiers on the ground have noted that even a one- or two-second advantage in command transmission provides a decisive edge. This rapid data flow allows for faster decision-making and more effective responses to incoming threats, a capability that current non-Starlink alternatives struggle to match.

What are the risks of this technological dependence?

The primary risk is that Ukraine's critical military capabilities are controlled by a private entity rather than a sovereign state. This dependence creates a vulnerability where service can be restricted or altered based on the decisions of a single individual or the political climate in the United States. Elon Musk recently highlighted this tension by accusing Ukraine of violating terms of service regarding drone strikes, warning that service could be terminated for such violations.

The recent slowdown of services in Ukraine has already demonstrated how quickly defensive capabilities can be compromised. This instability has sparked political concern in Europe, with officials like French MEP Christophe Grudler arguing that Ukrainian defense should not be subject to the whims of US political figures or private entrepreneurs. The ambiguity surrounding recent service restrictions—involving a complex interplay between the Pentagon, Donald Trump, and Musk—further underscores the instability of this arrangement.

How do current European alternatives compare to Starlink?

Currently, no immediate, high-performance alternative to Starlink exists that can fully replicate its battlefield utility. France's Eutelsat, through its OneWeb service, serves as the primary European alternative, but it operates with a significantly smaller constellation of approximately 600 active satellites compared to Starlink's more than 10,000. This massive scale difference impacts both coverage and the ability to provide specialized, low-latency services for small-scale hardware.

While Eutelsat can support many military needs, there are significant logistical and financial hurdles. According to Eva Berneke, former CEO of Eutelsat, the company's terminals are generally larger and roughly five times more expensive than Starlink's. While they are effective for mounting on tanks or cars, they lack the portability required for the small drones that are central to Ukraine's current defensive strategy.

What is the role of the EU's Govsatcom network?

Govsatcom serves as a short-term safety net for the European Union by sharing existing satellite capacities among member states. While Ukraine is seeking to join this network, the current framework has limitations regarding direct combat applications. Specifically, the network cannot currently be used for active warfare operations, such as the remote piloting of combat drones.

There is hope for expansion within this framework. The European Commission aims to integrate commercial providers, such as Eutelsat's OneWeb, into the programme by early next year. If successful, this would allow Ukraine to utilize Govsatcom as a reliable backup to Starlink. However, experts like Vincent Tourret caution that while a backup is essential for maintaining general connectivity, it will likely not be sufficient for high-intensity strikes or interceptions in its current state.

When will Iris² provide European satellite autonomy?

The Iris² project is the European Union's long-term strategic answer to the dominance of SpaceX, with an expected operational date in 2029. Unlike the broader commercial market, Iris² is designed as a defense-first programme, prioritizing the needs of governments, military forces, and emergency services. Ukraine has already been guaranteed access to this network once it becomes fully operational.

The architecture of Iris² differs significantly from the Starlink model. The network plans to utilize approximately 348 satellites across low and medium earth orbits. While this is a much smaller number than Starlink's constellation, proponents argue the design is more efficient. Kari Bingen, director of the Aerospace Security Project at CSIS, explains that by using satellites that can beam a more concentrated signal, the network can achieve wide coverage with fewer units. However, some analysts remain skeptical, suggesting that while Iris² provides sovereignty, it may not fundamentally change the technological landscape of satellite warfare.

FAQ: Ukraine's Satellite Connectivity

Why is Starlink so important for Ukraine?

Starlink provides the high-speed, low-latency internet required for modern battlefield operations. It allows Ukrainian troops to pilot drones, transfer real-time data, and maintain communications in areas where traditional infrastructure has been destroyed. This connectivity is considered a decisive factor in the effectiveness of their defensive maneuvers.

Can Europe replace Starlink immediately?

No, there is currently no immediate replacement that matches Starlink's scale and specialized hardware. While companies like Eutelsat offer satellite services, their constellations are much smaller, their terminals are larger and more expensive, and they currently lack the specific capabilities required for small-scale drone warfare.

What is the Iris² satellite network?

Iris² is a European Union initiative designed to create a sovereign, defense-oriented satellite constellation. It aims to reduce Europe's dependence on non-European providers like SpaceX. The project is expected to be operational by 2029 and will prioritize military and government communications.

Is Govsatcom a viable military option for Ukraine?

Govsatcom acts as a short-term backup rather than a primary combat tool. While it can provide essential connectivity, it is currently unable to support active warfare operations like drone piloting. The EU is working to expand its capabilities by including commercial providers in the near future.

What are the risks of relying on SpaceX?

The main risk is the lack of sovereign control. Because Starlink is a private service, its availability can be influenced by the decisions of Elon Musk or shifts in US political policy. This creates a strategic vulnerability where Ukraine's ability to defend itself depends on an external, private entity.

Key takeaways

  • Ukraine relies on Starlink for high-speed, real-time battlefield communications and drone control.
  • The current European alternative, Eutelsat OneWeb, has a much smaller satellite constellation.
  • The EU's Iris² network aims to provide sovereign satellite security by 2029.
  • Govsatcom offers a short-term connectivity backup but lacks current drone-piloting capabilities.
  • Starlink's small, lightweight terminals provide a tactical advantage over larger competitors.

Conclusion

The conflict in Ukraine has highlighted a critical gap in European strategic autonomy. While Starlink has been an indispensable asset for Ukrainian defense, the reliance on a private American provider introduces significant geopolitical and operational risks. Europe's response—a dual approach involving the immediate expansion of Govsatcom and the long-term development of the Iris² constellation—aims to ensure that future security is not subject to the decisions of external actors. Until Iris² becomes operational in 2029, Ukraine will likely continue to navigate the complex balance of utilizing superior commercial technology while seeking more stable, sovereign alternatives.
