Spain’s Defense Ministry disclosed Wednesday a formal budget of €1.6 billion to €2 billion (approximately $1.82 billion to $2.28 billion) for a national sovereign military satellite communications constellation that will be integrated into the European Union’s IRIS2 network — the bloc’s most ambitious answer yet to Europe’s battlefield dependence on Starlink. The disclosure, published in a Ministry report tied to a meeting of Spain’s National Committee for Technological Security and Sovereignty, provides the first official budget envelope for a program previewed in May by Prime Minister Pedro Sánchez and signals that IRIS2 is no longer a Brussels abstraction but a program drawing sovereign capital from member states.

Spain’s commitment surpasses Poland’s earlier pledge of €470 million (approximately $536 million) for six dedicated IRIS2 satellites, making Madrid the largest single national backer of the EU’s military satellite program to date.

The strategic logic behind Spain’s investment is inseparable from a documented vulnerability. Ukraine’s armed forces rely on thousands of Starlink terminals for battlefield command-and-control and drone operations — communications that experienced a 2.5-hour complete outage in July 2025 when a SpaceX software failure knocked the service offline across the entire front. “Starlink is down across the entire front,” Ukraine’s drone force commander Robert Brovdi wrote in real time on Telegram, noting that combat missions had to proceed without video feeds. The incident crystallized what European defense planners had already argued: that sovereign military communications routed through a private American company controlled by a single individual represents a structural, not merely theoretical, security risk.

Why Europe Is Spending Billions to Leave Starlink Behind

Spain’s Prime Minister Sánchez put it plainly at the Madrid Space Congress in May 2026. Dependence on foreign commercial satellite providers for military connectivity, his government argued, amounted to a form of “servitude.” That framing echoed the position of EU Commissioner for Defence and Space Andrius Kubilius, who told the European Space Conference in January 2026 that he had “asked all partners to step up and speed up IRIS2” and expressed confidence that the first batch of satellites would be ready for deployment by 2029.

The urgency crystallized after the February 2025 Trump-Zelenskyy meeting and the suspension of US military aid to Ukraine, which raised direct questions about how much longer Starlink services — operated by a private company with no treaty obligations to any European government — would remain available to allied forces.

How IRIS2 Is Engineered for Sovereignty, Not Just Connectivity

IRIS2 — the Infrastructure for Resilience, Interconnectivity and Security by Satellite — is the EU’s third flagship space program after Galileo (navigation) and Copernicus (Earth observation), and it is structurally different from either commercial constellation competing in the same orbital lanes. The program is structured as a 12-year public-private concession contract between the European Commission and the SpaceRISE consortium — comprising satellite operators SES (Luxembourg), Eutelsat (France), and Hispasat (Spain) — supported by Thales Alenia Space, OHB, Airbus Defence and Space, Telespazio, Deutsche Telekom, Orange, Hisdesat, and Thales Six as core subcontractors. Under this structure, SpaceRISE bears the design, construction, and operational risk; the EU guarantees governmental access to the constellation for the duration; and the consortium recovers investment through commercial capacity sold to non-governmental users. Crucially, the EU does not own the satellites — it purchases guaranteed sovereign access. That arrangement is what makes the €6.5 billion (approximately $7.41 billion) public funding component economically viable at a total program cost of €10.5 billion (approximately $11.96 billion).

The constellation is designed as a multi-orbit architecture of 290 satellites: 272 in low Earth orbit at 1,200 kilometers (746 miles) altitude and 18 in medium Earth orbit at 8,000 kilometers (4,971 miles) altitude. The combination is deliberate. LEO satellites at 1,200 km provide round-trip communications latency of roughly 20 to 40 milliseconds — the low latency required for real-time military command-and-control and drone operations. MEO satellites at 8,000 km cover a much wider geographic footprint per satellite, providing resilient backup coverage. Neither a pure LEO constellation nor a pure MEO constellation delivers both attributes simultaneously; the multi-orbit design is IRIS2’s core technical claim to being a genuine Starlink-class capability for governmental users, not merely a slower GEO-satellite stopgap.

The security architecture adds a layer that commercial constellations do not carry. IRIS2 will rely on quantum cryptography through the European Quantum Communication Infrastructure (EuroQCI) and a “secure-by-design” approach for its entire communications stack — a technical specification that reflects the system’s intended military-grade users, from EU embassies to NATO-allied defense ministries.

Spain’s Dual Role: Backbone of the Ground and Pioneer of Low Orbit

Spain’s involvement in IRIS2 runs far deeper than a financial commitment. Hispasat — Spain’s largest satellite operator, a subsidiary of the Indra Group in which the Spanish state holds approximately 28% of shares through the state industrial holding company SEPI — holds two of the most structurally significant roles in the entire SpaceRISE consortium.

First, Hispasat is responsible for designing, developing, and implementing the constellation’s ground segment: all control centers, service stations, and telecommand and telemetry nodes that will manage and operate IRIS2’s different orbital layers and connect the constellation to terrestrial networks. That ground architecture must meet the stringent security and redundancy requirements of a system serving EU governments in crisis conditions.

Second, Hispasat will lead IRIS2’s Very Low LEO orbital layer — satellites operating below 750 kilometers (466 miles) in altitude. This layer is designed for innovative missions that complement the main LEO-High and MEO operational layers. The technical distinction matters: Very Low LEO orbits experience higher atmospheric drag, requiring continuous propulsion for orbit maintenance, but offer lower signal latency than higher LEO, higher spatial resolution for potential intelligence applications, and the natural orbital decay that limits space debris accumulation. The Very Low LEO layer is specifically designed to involve European startups and small and medium-sized enterprises — a deliberate attempt to route IRIS2 investment into the commercial space ecosystem rather than concentrating it entirely among established primes.

Spain’s national PEM Satcom multiórbita program — one of 15 Special Modernization Programs the Defense Ministry is launching in 2026 — covers the full stack of sovereign capability: space segment development, ground control and management infrastructure, user terminal procurement, and complete lifecycle operation. The program does not simply subscribe Spain to IRIS2 as a service consumer; it builds Spain’s own sovereign space segment that will be compatible with and contribute to the broader EU constellation while remaining under Spanish national control for defense purposes.

What Europe Still Has to Prove

Spain’s budget commitment lands at a moment of genuine program risk that its announcement framing does not address. IRIS2 has no satellites in orbit. The full-capacity system, originally projected for 2027, has slipped to 2030 under the official political target — and industry analysts calculated that the in-service date has slipped from an initial estimate of 2024 through 2026, 2028, and 2030, with the full-capacity constellation potentially not arriving until 2032 per Space Intel Report’s June 2025 industry estimate. The program is responding to these pressures by adding 66 smaller early-delivery LEO satellites for launches starting in 2029, but with limited capabilities rather than the full 5G digital capacity originally specified — an interim step that buys political credibility at the cost of initial performance, according to Space Intel Report.

Most significantly, the prime satellite manufacturing contract for IRIS2’s 272-satellite LEO-High layer — the backbone of the constellation — has not been awarded. As of July 29, 2026, SpaceRISE is conducting competitive dialogues between two bidders: Airbus Defence and Space (France) and Aerospacelab (Belgium). Request for Proposals for 272 LEO satellites were issued on January 5, 2026; binding proposals are under evaluation; Critical Design Reviews are targeted for 2026-2027. No prime contractor has been selected. Spain’s €1.6–2 billion ($1.82–2.28 billion) commitment is therefore a sovereign capital bet on a program still in the process of selecting its most critical industrial supplier.

Critics have raised the scale question bluntly. T.I. Weintraub, chief growth officer at ATLAS Space Operations, noted at the Space Tech Expo Europe in late 2024 that Starlink will likely operate 12,000 satellites by the time IRIS2 reaches orbit. The full IRIS2 LEO constellation is projected to deliver approximately 2 terabits per second of throughput — equivalent, per Quilty Space’s analysis, to roughly two ViaSat-3 GEO satellites — while Starlink’s network at the same time will be orders of magnitude larger. Former Eutelsat CEO Eva Berneke warned that if European governments begin freelancing with their own individual requirements — exactly what Spain’s national program represents in one sense — the result could be cost overruns and schedule slippage at the consortium level.

Spain’s bet is that the strategic imperative outweighs the execution risk. The geopolitical record since 2022 has consistently proved that argument correct.

IRIS2 Today: GOVSATCOM Fills the Gap

While IRIS2 remains under construction, the EU is not without sovereign satellite communications. The EU Governmental Satellite Communications program (GOVSATCOM) became operational on January 14, 2026, providing secure, encrypted satellite access to all EU member states by pooling capacity from eight existing geostationary satellites contributed by five countries: France, Spain, Italy, Greece, and Luxembourg. Spain is one of those five capacity contributors.

GOVSATCOM operates through a centralized ground hub architecture managed by a consortium led by GMV, the Spanish aerospace and defense company, in partnership with Indra and Hisdesat — further deepening Spain’s structural role in European sovereign space infrastructure. The system is intentionally designed as a temporary bridge: GEO satellites at 36,000 kilometers (22,369 miles) altitude produce round-trip communications latency of roughly 600 milliseconds — adequate for diplomatic traffic and crisis coordination, but not for the low-latency military command-and-control that IRIS2’s LEO layer is intended to provide.

Norway and Iceland joined GOVSATCOM and IRIS2 in March 2026, expanding the program beyond EU member states. Germany broke ground on a permanent GOVSATCOM Hub facility in Cologne in June 2026, one of two hubs — alongside a site in Athens — that will replace the interim operational setup. A European sovereign satcom architecture is being built, piece by piece. Spain’s €1.6–2 billion ($1.82–2.28 billion) national program is, as of Wednesday, its most significant funded component.

Frequently Asked QuestionsWhat is Spain’s PEM Satcom multiórbita program, and how does it relate to IRIS2?

PEM Satcom multiórbita is Spain’s national Special Modernization Program for sovereign military satellite communications. It covers the design, development, and operation of a multi-orbit satellite constellation that will be compatible with and integrated into the EU’s IRIS2 network. Spain’s national system gives Madrid independent control over its most sensitive military communications while contributing to and benefiting from the broader European network. The program covers the full technology stack: space segment, ground control infrastructure, user terminals, and complete lifecycle operation.

When will IRIS2 actually deliver military-grade, low-latency satellite communications?

The European Commission’s political target is initial government services in 2029, with full operational capability in 2030. In practice, the timeline is more complex. IRIS2 is adding 66 smaller early-delivery satellites for initial 2029 launches with limited capabilities, while the full 272-satellite LEO-High constellation — which will deliver the low-latency connectivity competitive with Starlink — is targeted for completion around 2032 by industry estimates. No satellites have been launched yet, and the prime manufacturing contract for the LEO-High layer has not been awarded as of July 2026.

Why can’t European militaries just continue using Starlink?

They can and do — but the Ukraine conflict demonstrated the structural risk. Starlink is owned and operated by a private American company; its continued provision to allied forces depends on the decisions of that company’s leadership, not on any treaty or legal obligation. A documented outage in July 2025 knocked Starlink-dependent Ukrainian military communications offline for 2.5 hours across the entire front. More fundamentally, the concern is long-term coercive dependency: a military that cannot communicate without a foreign commercial provider’s cooperation is not fully sovereign in its defense posture.

How does the quantum cryptography in IRIS2 differ from what Starlink uses?

IRIS2 is designed from the ground up to use quantum key distribution through the European Quantum Communication Infrastructure (EuroQCI) — a cryptographic method that exploits quantum physics to make eavesdropping on communications mathematically detectable. Starlink is a commercial broadband service not designed around quantum-secure government communications. IRIS2’s secure-by-design architecture reflects its intended governmental and military users; the quantum layer is one reason European defense planners view IRIS2 as categorically different from simply buying access to a commercial constellation.
