Munich-based Isar Aerospace secures major funding to expand rocket production and infrastructure, positioning Europe as a competitive force in global space access.
Isar Aerospace Secures €150M Financing: A Strategic Leap for European 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.
Scaling Production and Infrastructure: The Impact of the Eldridge Investment
Manufacturing Expansion and Vertical Integration
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
Launch Infrastructure and Operational Flexibility
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.
Resilience After Setback: Learning from Launch Failure
The March 2025 Launch and Technical Response
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.
“As I have seen before, it often takes a few attempts to reach orbit.”, Bulent Altan, Isar Board Member and former SpaceX VP
Investor Confidence and Strategic Timing
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.
Conclusion: A Pivotal Moment for European Space Sovereignty
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.

Starfighters Space Plans STARLAUNCH 1 Captive-Carry Flight Test
Starfighters Space schedules a December 2026 captive-carry flight of STARLAUNCH 1 aboard an F-104 Starfighter from Kennedy Space Center.
Starfighters Space, Inc. (NYSE American: FJET) will conduct the first captive-carry flight test of its STARLAUNCH 1 suborbital development vehicle using a Lockheed F-104 Starfighter in December 2026. The mission marks the program’s transition from ground-based design to active flight testing, establishing operational procedures for future drop tests and powered launches.
In a press release issued on October 13, 2026, the company confirmed that the airframe design for STARLAUNCH 1 has been finalized and inert flight hardware has been ordered. The December 2026 flight will originate from the company’s base at the National Aeronautics and Space Administration (NASA) Kennedy Space Center and proceed to the Federal Aviation Administration (FAA) licensed Cecil Spaceport in Jacksonville, Florida.
Transitioning to active flight testing
The upcoming captive-carry flight represents a critical milestone for the STARLAUNCH program. Inert flight hardware is expected to arrive at the Kennedy Space Center hangar in November 2026. Engineering teams will then begin assembly and testing of the rocket-aircraft interface to ensure the Lockheed F-104 Starfighter can safely carry the suborbital vehicle.
Tim Franta, CEO of Starfighters Space, stated that the planned captive-carry flight will move STARLAUNCH 1 from design and ground-based development directly into flight testing.
“Our approach is deliberately incremental: build the hardware, integrate it with the aircraft, fly it, collect data, and use those results to advance toward separation and powered flight. This work on STARLAUNCH 1 is also expected to generate engineering and operational experience to inform the future development of STARLAUNCH 2.”
The December 2026 mission is designed to test aircraft integration, evaluate aerodynamic behavior, and establish operational procedures. Piercarlo Ciacchi, Director of Flight Operations and Chief Pilot of Starfighters Space, noted that the flight will capture essential data for the FAA and the United States Space Force (USSF).
“December’s captive-carry mission would essentially be step one of a multi-flight campaign, building processes for our launch team while capturing data for the FAA and the Space Force as we move toward propulsive air launch.”
Following the December 2026 captive-carry mission, the company plans to conduct a drop test over the Atlantic Ocean. This will be followed by a demonstration of the integrated propulsion system.
Hardware integration and propulsion development
The December 2026 flight may also serve a dual purpose by incorporating hardware from the company’s Wind Tunnel in the Sky program. On October 8, 2026, Starfighters Space announced the completion of its first flight hardware for this initiative, manufactured by Italian engineering firm Robby Moto Engineering S.R.L. (RME). The assembled flight articles measure 3.65 meters in length and 178 millimeters in diameter.
During the STARLAUNCH 1 flight, the company may fly this newly completed Wind Tunnel in the Sky hardware under the opposite wing of the Lockheed F-104 Starfighter on a customer-funded rideshare mission. In this configuration, the hardware will simultaneously serve as an aerodynamic counterweight for the STARLAUNCH 1 vehicle.
Propulsion development is also advancing in parallel. On September 9, 2026, Starfighters Space signed a Memorandum of Understanding with Florida-based Vaya Defense & Space to evaluate the Vortex-Hybrid rocket engine for the STARLAUNCH system. Data collected during the December 2026 flight will support Vaya Defense & Space in developing a hybrid rocket motor aligned with the specific requirements of STARLAUNCH 1.
The STARLAUNCH development pathway
Starfighters Space operates the world’s only commercial fleet of flight-ready Mach 2+ supersonic aircraft. Based at the Kennedy Space Center, the company utilizes its fleet to provide pilot training, in-flight testing, and microgravity research, while actively developing air-launch capabilities for space payloads.
The STARLAUNCH program is the company’s primary air-launch initiative. STARLAUNCH 1 serves as the initial suborbital development vehicle, designed to pave the way for STARLAUNCH 2, a larger vehicle intended for orbital launches.
The program has met several technical milestones throughout the year. On January 21, 2026, the company announced the successful completion of subsonic and supersonic wind tunnel testing for STARLAUNCH 1. These tests demonstrated clean separation behavior at Mach 0.85 and Mach 1.3. Subsequently, on February 20, 2026, the program advanced to a Critical Design Review (CDR) with support from GE Aerospace to confirm design maturity.
Addressing the hypersonic testing bottleneck
The aerospace and defense industries are currently facing a significant bottleneck in hypersonic testing. Traditional ground-based wind tunnels are heavily oversubscribed and typically offer only seconds of test time per run. Airborne platforms like the Lockheed F-104 Starfighter fleet offer sustained testing at speeds exceeding Mach 2 in real atmospheric conditions.
This capability provides a complementary method to compress development timelines for defense primes and commercial space companies, allowing them to gather sustained aerodynamic data outside of traditional laboratory environments.
AirPro News analysis
We view the activation of the STARLAUNCH flight test campaign as a notable indicator of the shifting economics in high-speed aerospace testing. By utilizing legacy supersonic platforms to bypass the constraints of ground-based infrastructure, commercial operators are positioning themselves to capture overflow demand from defense primes and space launch developers. If the December 2026 captive-carry flight successfully validates the aerodynamic integration, it will likely accelerate the timeline for propulsive air-launch systems, offering a viable alternative to traditional vertical launch architectures for smaller payloads.
The dual-use nature of the December 2026 flight, which tests the launch vehicle while simultaneously flying a commercial payload as a counterweight, demonstrates a highly efficient approach to flight test monetization. This strategy allows the operator to offset development costs while proving out multiple distinct business lines on a single sortie.

Space Cargo Unlimited Books SpaceX Starfall for 2028 Mission
Space Cargo Unlimited signs with SpaceX to launch a 1-tonne in-space factory on Starfall in 2028, its first European customer.
Luxembourg-based startups Space Cargo Unlimited has secured a contract with SpaceX to launch a one-tonne modular space factory aboard the new Starfall reentry capsule. The mission, targeted for 2028, marks a significant capacity increase for commercial in-space manufacturing and establishes the company as the first known European customer for the Starfall vehicle.
Announced on September 15, 2026, the agreement will utilize Space Cargo Unlimited’s BentoBox payload platform to produce materials in Low Earth Orbit (LEO) before returning them to Earth. According to Reuters, the startup is currently in discussions with more than 100 potential customers, with approximately 40 percent originating from the life sciences and biotechnology sectors.
Scaling up microgravity production
The upcoming 2028 mission represents a tenfold increase in payload capacity for Space Cargo Unlimited. The company previously operated missions with a 100-kilogram limit. The Starfall contract expands that capacity to 1,000 kilograms, or one metric ton.
In a press release detailing the agreement, Space Cargo Unlimited Co-founder and CEO Nicolas Gaume highlighted the historical barriers to orbital production.
“For more than thirty years, we’ve known that manufacturing in microgravity can create materials and products that simply cannot be produced on Earth. The challenge has never been the science. The challenge has been making access commercially practical, repeatable and scalable.”
Demand for the expanded capacity appears robust. Reporting by Payload indicates that Space Cargo Unlimited has already sold one-third of its 1,000-kilogram allocation for the 2028 flight.
Starfall and the commercialization of Starship
The Space Cargo Unlimited contract is part of a broader commercial rollout for SpaceX’s Starfall reentry vehicle, which is designed to fly on the heavy-lift Starship launch system. SpaceX conducted the first demonstration mission of the Starfall capsule on a Falcon 9 rocket on June 23, 2026.
Other aerospace integrators are also securing space on future Starfall flights. In August 2026, Redwire subsidiary SpaceMD announced plans to fly 32 variants of its PIL-BOX payloads on a 2028 Starfall mission to research microgravity drug development. On September 21, 2026, German launch integrator Exolaunch confirmed an agreement for a Starfall mission scheduled for no earlier than 2029.
SpaceX is actively transitioning the Starship program from developmental testing to revenue-generating operations. Speaking to the vehicle’s long-term capabilities, SpaceX CEO Elon Musk noted the company’s aspirations are to deliver well over one million tons to orbit annually.
While Space Cargo Unlimited has publicized the 2028 target for its BentoBox mission, SpaceX has not officially confirmed the specific timetable for this flight.
AirPro News analysis
We view the transition from 100-kilogram research payloads to one-tonne commercial batches as a critical threshold for the in-space manufacturing sector. The high concentration of prospective biotechnology customers suggests that pharmaceuticals and advanced materials will likely drive the initial economic viability of orbital factories. If SpaceX can maintain the projected 2028 timeline for Starfall operations, the bottleneck for microgravity manufacturing will shift from launch availability to payload integration and terrestrial market demand.

In a press release issued on September 1, 2026, Dawn Aerospace detailed the agreement, which leverages the rapid reusability of the Aurora spaceplane to provide high-cadence microgravity testing. Astral Materials plans to use these flights to refine its microgravity furnace hardware. The system is designed to reduce gravity-driven defects, such as convection and sedimentation, during the growth of semiconductor crystals. These materials have potential applications in photonics, quantum computing, and high-power electronics.
Rapid iteration in suborbital flight
The Aurora spaceplane is designed to reach a top speed of Mach 3.7 and a maximum altitude of 100 kilometers, providing payloads with up to 127 seconds of microgravity per flight. According to the manufacturers, the vehicle supports a four-hour turnaround time between flights. This operational tempo allows researchers to conduct multiple tests within a single day.
Astral Materials Chief Technology Officer Jiya Janowitz highlighted the value of this cadence for hardware development, noting that payloads can be recovered in approximately 45 minutes.
“We can test an idea, recover it in around 45 minutes, make an adjustment on the ground and test it again later that same day. That kind of rapid iteration has never existed for microgravity manufacturing, and it fundamentally changes how quickly we can develop our technology.”
Astral Materials Chief Executive Officer Dr. Jessica Frick stated that the Aurora spaceplane provides a practical pathway to validate manufacturing systems before scaling to commercial production in orbit, where longer-duration microgravity is available.
Commercial operations and Oklahoma infrastructure
Commercial flight operations for the Astral Materials campaign are slated to begin in 2028 at the Infinity One Oklahoma Spaceport. The Oklahoma Space Industry Development Authority (OSIDA) welcomed the partnerships in an official social media statement on September 1, 2026, emphasizing the state’s focus on attracting high-cadence commercial spaceflight operations.
This agreement follows an April 16, 2026, announcement in which Dawn Aerospace and OSIDA launched the Suborbital Spaceplane Challenge. That initiative offered United States researchers up to 25 flights aboard the Aurora spaceplane to stimulate utilization of the Oklahoma facility.
Dawn Aerospace Chief Executive Officer Stefan Powell noted that routine access is required to transition microgravity manufacturing from a scientific curiosity to a viable industry, comparing the need for rapid experimentation to previous industrial revolutions.
AirPro News analysis
The partnership between Dawn Aerospace and Astral Materials highlights a critical gap in the current space manufacturing ecosystem. While orbital platforms like the International Space Station offer long-duration microgravity, the cost and lead times associated with orbital launches prohibit the rapid trial-and-error necessary for hardware development. Suborbital spaceplanes like Aurora serve as an essential stepping stone. By providing brief but frequent periods of microgravity, these vehicles allow companies to validate complex systems before committing to expensive orbital deployments.
We note a minor discrepancy in Dawn Aerospace’s published materials regarding the commencement of operations at the Oklahoma site. The main announcement targets 2028 for commercial flights, while the company’s boilerplate text references 2027. Regardless of the exact start date, establishing a reliable suborbital testbed will be vital for the commercial viability of in-space manufacturing applications.
