Isar Aerospace Raises €150M to Boost European Space Launch Capabilities
Munich-based Isar Aerospace secures major funding to expand rocket production and infrastructure, positioning Europe as a competitive force in global space access.
In a major development for the European space sector, Isar Aerospace announced on June 25, 2025, that it has secured a €150 million convertible bond agreement with Eldridge Industries. This capital injection arrives at a critical juncture for the Munich-based launch company, just months after its first orbital launch attempt and amid an intensifying global race for affordable and reliable access to space. The financing not only bolsters Isar’s manufacturing and launch capabilities but also underscores growing investor confidence in Europe‘s emerging space ecosystem.
As the European Union grapples with reduced launch capacity due to setbacks with legacy systems like Ariane 6 and Vega C, companies like Isar Aerospace are stepping into the void. With a vertically integrated production model and a focus on cost-efficient satellite launches, Isar is positioning itself as a cornerstone of Europe’s sovereign access to space. The Eldridge investment marks a significant milestone in this journey, enabling the company to scale production, enhance infrastructure, and prepare for its next launch attempt.
One of the primary allocations of the €150 million convertible bond is the expansion of Isar Aerospace’s production facilities near Munich. The company has acquired a 40,000 m² site touted as “the world’s most modern production facility for orbital launch vehicles.” This new facility will enable Isar to scale up to 40 launches annually by 2028, using advanced robotic assembly lines and additive manufacturing techniques that reduce manual labor by up to 70%.
Isar’s vertical integration strategy is a key differentiator in the European space landscape. With 80% of its components manufactured in-house, including 3D-printed Aquila engines, the company can maintain tighter control over quality, reduce costs, and respond more swiftly to technical challenges. This model contrasts sharply with the fragmented supply chains of traditional aerospace firms, offering Isar greater resilience in a competitive and volatile market.
The Spectrum rocket, Isar’s flagship vehicle, reflects this efficiency-driven philosophy. A two-stage, 28-meter launcher powered by liquid oxygen and propane, Spectrum is designed to deliver payloads of up to 1,000 kg to low Earth orbit (LEO) at a target cost of €10,000 per kilogram. While this pricing still trails behind U.S. competitors like SpaceX and Rocket Lab, it represents a significant improvement over legacy European offerings and positions Isar competitively in the emerging small satellite market.
“This investment demonstrates strong confidence from global markets in our efforts to build a new space champion.”, Daniel Metzler, CEO of Isar Aerospace
Beyond production, the Eldridge funding will support enhancements to Isar’s launch infrastructure. The company operates from Norway’s Andøya Spaceport and maintains integration facilities at the Guiana Space Centre in French Guiana. These dual launch sites enable Isar to conduct simultaneous campaigns, improving scheduling flexibility and increasing launch cadence potential.
Spectrum’s design further supports operational agility. Its second-stage engine is capable of multiple ignitions, eliminating the need for additional kick stages and allowing for complex deployment missions. The vehicle supports three configurations, Dedicated, Lead, and Rideshare, catering to a wide range of customer needs, from commercial satellite operators to governmental agencies.
Isar’s infrastructure strategy aligns with its broader mission to democratize space access. By offering a diversified and cost-effective launch service, the company aims to reduce Europe’s reliance on non-European launch providers, a strategic objective gaining urgency amid geopolitical tensions and supply chain disruptions. Isar Aerospace’s first orbital launch attempt on March 30, 2025, ended in failure just 30 seconds after liftoff. The Spectrum rocket lost control and impacted the Norwegian Sea, triggering the Flight Termination System. While the failure was a setback, the company treated it as a critical learning opportunity, capturing over 1,200 telemetry channels that provided valuable performance data.
In the immediate aftermath, Isar emphasized its parallel production strategy. Second and third Spectrum units were already under assembly, allowing the company to maintain momentum and avoid extended downtime. The next launch is scheduled for late 2025 and will feature upgraded avionics and thrust vector control systems to address the issues identified during the first mission.
Industry experts have drawn comparisons to SpaceX’s early development path, noting that initial failures are often necessary steps in the iterative design and testing process. Isar’s financial backing, now exceeding €550 million, gives it a cushion that early New Space pioneers lacked, enabling a faster and more robust recovery trajectory.

The timing of the Eldridge investment, just months after a failed launch, speaks volumes about investor confidence in Isar’s long-term vision. Convertible bonds, which convert to equity in future financing rounds or IPOs, provide immediate liquidity without diluting current shareholders. This financial structure is particularly well-suited for high-capital, high-risk ventures like space launch services.
By securing regulatory approvals and closing the deal swiftly, Isar has positioned itself to execute on its roadmap without delay. The company’s ability to attract institutional capital even after a failed mission illustrates the growing maturity of Europe’s commercial space sector and the perceived strategic value of independent launch capabilities.
Looking ahead, Isar is preparing for a potential IPO and aims to meet a 12-launch-per-year threshold by 2027. Achieving this cadence will be critical to validating its business model and justifying its valuation in public markets. The company also stands to benefit from upcoming European Space Agency funding opportunities, such as the €169 million Launcher Challenge expected to be allocated in late 2025.
Isar Aerospace’s €150 million financing agreement with Eldridge Industries marks a turning point not only for the company but also for the European space industry at large. It represents a vote of confidence in Europe’s ability to develop indigenous launch capabilities and reduce reliance on foreign providers. With a vertically integrated production model, advanced manufacturing techniques, and a growing launch infrastructure, Isar is well-positioned to become a leading player in the global small satellite market.
As the company prepares for its next launch and continues scaling operations, the stakes are high. Success could establish a new model for public-private collaboration in space, while failure could reinforce Europe’s dependence on external actors. Either way, Isar Aerospace is now at the forefront of a broader movement to secure Europe’s place in the final frontier. What is the purpose of the €150 million financing? What is a convertible bond?
