Rheinmetall ICEYE Space Solutions has given the Bundeswehr direct access to several synthetic aperture radar (SAR) reconnaissance satellites dedicated exclusively to German military use, the Neuss-based joint venture announced on October 6, 2026. German forces can now task the satellites independently under the SPOCK 1 program, and the company has started SAR satellite production at its plant in Neuss, near Düsseldorf.
The milestone comes less than ten months after the Federal Office of Bundeswehr Equipment, Information Technology and In-Service Support (BAAINBw) signed the operator contract on December 18, 2025, a day after the Bundestag budget committee approved it. Valued at approximately €1.7 billion gross and running to the end of 2030, SPOCK 1 is one of the first large awards under the €35 billion that Defense Minister Boris Pistorius committed to military space projects through 2030. It targets a specific gap: persistent, all-weather imaging at the tactical and operational level for German land forces on NATO’s eastern flank.
How Bundeswehr SAR Satellites Under SPOCK 1 Support the Lithuania Brigade
SPOCK 1 stands for SAR Space System for Persistent Operational Tracking, Stage 1. According to the BAAINBw, its purpose is to detect adversary mobilization and force build-ups early and feed that imagery into land operations. The primary user is Panzerbrigade 45, formally established on April 1, 2025, and based at the Rūdninkai training area, roughly 30 km from the Belarusian border. The brigade is planned to reach 4,800 soldiers and 200 civilian staff, with full operational capability by the end of 2027.
The contract buys a service, not hardware. The constellation remains the property of Rheinmetall ICEYE Space Solutions, which operates the satellites, manages the ground station, and runs AI-assisted first-pass image exploitation before delivering a high daily volume of images. Under the contract’s phasing, initial operational capability was scheduled from October 1, 2026, with full operating capability set for April 2028. The joint venture also supplies its sovereign AI analysis software and exercise data on request. The company has not disclosed how many satellites are currently available to German operators.
SPOCK 1 adds a high-revisit layer to existing German SAR capacity. The three-satellite SARah system, ordered in 2013 for roughly €800 million, pairs the Airbus-built SARah-1, an active phased-array satellite of about 4,000 kg launched on June 18, 2022, with two OHB passive reflector satellites launched on December 24, 2023. SARah was built for strategic, worldwide imaging from a few large spacecraft; SPOCK 1 trades satellite size for numbers and revisit rate.
How Rheinmetall ICEYE Is Scaling Gen4 SAR Satellite Production in Neuss
Rheinmetall holds 60% of the joint venture and ICEYE 40%. The partners signed a memorandum of understanding in May 2025 and formally established the company in Neuss in November 2025, at a site Rheinmetall is converting from automotive production. The plant combines production, integration, testing, and quality assurance, with a stated goal of building and certifying several dozen satellites per year. Rheinmetall CEO Armin Papperger said the start of production shows the group can scale space technology industrially in Germany. ICEYE CEO Rafal Modrzewski credited years of operating ICEYE’s commercial constellation for the speed of delivery, adding: “Our job now is to hold that pace as the system grows.”
Rheinmetall has not published specifications for the SPOCK 1 spacecraft. ICEYE stated in November 2025 that the Neuss plant would build its fourth-generation (Gen4) design. Publicly available specifications indicate Gen4 operates in X-band with resolution of up to 16 cm, an imaging bandwidth of 1,200 MHz, and capacity for up to 500 images per satellite per day. Its larger antenna extends high-resolution coverage to a 400 km area, against 150 km for the previous generation. Earlier ICEYE satellites weighed about 85 kg.
Under frequent Baltic cloud cover and long winter nights, those figures matter. X-band radar images through darkness, cloud, and smoke, and sub-meter resolution combined with repeated passes supports change detection, a technique well suited to spotting vehicles massing in assembly areas or fresh earthworks near a border. In an April 1, 2026, filing with the International Telecommunication Union, the joint venture described a network of 190 satellites in four orbital planes at 650 km, a spectrum reservation rather than a firm production order.
Analysis: SPOCK 1 shifts German military space from owning a few exquisite satellites to buying exclusive, assured access to a commercially derived, proliferated constellation. The gain is speed: SARah took a decade from order to completed constellation, while SPOCK 1 moved from contract to tasking in under ten months. The cost is dependence on a single industrial operator, at a rising price; Finance Ministry documents shared with the Bundestag budget committee put the potential total at up to €2.7 billion. For NATO, a dedicated radar layer over the eastern flank closes an ISR gap that the Netherlands and Finland have also moved to fill through their own ICEYE contracts.
The next markers are the number and launch dates of dedicated SPOCK 1 satellites, neither yet disclosed, and progress toward full operating capability in April 2028. The contract allows two one-year extensions to the end of 2032, tied to the availability of a successor system, SPOCK 2; roughly €860 million earmarked for those extensions has not been approved. Whether Neuss reaches several dozen satellites per year, and how much of that output goes to export customers, will decide whether the plant becomes a European production hub or a single-program line.
