Millions extra for "Spock": Bundeswehr radar satellites much more expensive

Contents

The Bundeswehr is facing a technological turning point in space. However, the price for new sovereignty in reconnaissance threatens to rise massively. Under the name “Spock” (Spacesystem for persistent operational tracking), the Ministry of Defence plans to build a constellation of around 40 radar satellites. The system is intended to provide high-resolution data on Russian troop movements and mobilization activities to the new Panzerbrigade 45 in Lithuania, almost in real time. However, a confidential document from the Ministry of Finance to the Bundestag's Budget Committee, which Der Spiegel has seen, reveals a significant funding gap: the project is already up to 579.5 million euros pricier than planned before its launch.

Previously, a budget of around 1.76 billion euros, already considerable, had been allocated for the project. With the newly revealed additional costs and considering all contractual options until 2033, the total volume could rise to over 2.7 billion euros.

According to the report, the reason for the price surge is bureaucratic in nature: the “specific requirements” for the operator contract only became known during the final bidding process at the end of 2025. As the budget for 2026 was already well advanced at that time, the additional millions could no longer be planned in time. Nevertheless, according to Boris Pistorius' (SPD) ministry, the project cannot be delayed, as the safety of German soldiers on the NATO eastern flank directly depends on this data.

High-Tech Against the Darkness

The technical core of Spock is Synthetic Aperture Radar (SAR) technology. While conventional optical satellites rely on sunlight and are blinded by cloud cover or fog, radar satellites function independently of weather and time of day. They emit their microwave pulses and register their echoes, allowing them to deliver precise images of the Earth's surface even in cloudy conditions or at night. This capability is essential for the military to detect troop movements at any time. The Federal Intelligence Service (Bundesnachrichtendienst) also wants reconnaissance eyes in space, but these are delayed.

To handle the data volumes from the 40 satellites, the Bundeswehr is relying on AI. This is intended to automatically analyze the captured images and report changes in the landscape or troop concentrations. It's not just about pure photos: the system is supposed to be able to independently identify the type of objects detected – such as tank types or supply units. The goal is continuous and gapless tracking of relevant developments on the ground. The first images from the system are expected from October of this year, underscoring the time pressure.

Controversial Direct Award

The legal framework for the procurement is noteworthy. The contract for “Spock” was not put out for international tender but was awarded directly to the German-Finnish joint venture Rheinmetall Iceye Space Solutions (RISS). This was made possible by the Planning and Procurement Acceleration Act, which came into force in February 2026. The Bundeswehr justifies this step with the urgency and a market survey. This survey indicated that the technology from Iceye and Rheinmetall best met the military requirements.

Nevertheless, resistance is brewing in the industry. International providers and also German space companies criticise the lack of open competition and the unusually high costs. An industry insider complained that the project was originally intended for the retrieval of satellite data but has now expanded to a more expensive procurement of a complete infrastructure.

From University Project to Arms Giant

The technological basis of Spock comes from Finland. Iceye's story began over ten years ago at Aalto University near Helsinki. There, a team developed the minisatellite Aalto-1. Founders Rafal Modrzewski and Pekka Laurila pursued the idea of miniaturising massive and expensive radar technology to such an extent that it could fit onto small satellites weighing less than 100 kilograms. In 2018, the company's X1 became the world's first commercial SAR satellite in this weight class to fly into space. Today, Iceye operates a fleet of over 40 active Earth observation satellites.

The Ukrainian military uses Iceye data intensively for warfare, which has increased the attractiveness of the system for other European countries such as Poland, Portugal, and Sweden. The cooperation with Rheinmetall secures the German defense contractor sales rights in Germany and Hungary. Satellite production is scheduled to begin in Neuss from mid-2026.

Part of a Larger Space Offensive

Spock is embedded in a comprehensive offensive by the German government in space. The new Space Security Strategy aims to reduce dependence on US intelligence information and ensure the protection of critical orbital infrastructure.

Spock's full operational capability is targeted for April 2028, for which the groundwork must now be laid. A new integration and testing center on the Norwegian island of Andøya is set to ensure smooth operation from 2027. Despite the additional costs and criticism of the award, the German government signals: In an era where information is the most valuable currency on the battlefield, a gapless view from above is worth a lot of money.
