- Munich‘s Isar Aerospace has closed a €270M Series D round, backed by Island Green Capital and Molten Ventures, alongside HV Capital, Lakestar, UVC Partners, and KfW Capital, to expand global operations and ramp up serial production of its Spectrum launch vehicle.
- A launch window for Spectrum’s long-awaited qualification flight opens June 15–21 from Andøya, Norway, which is the fourth attempt at Mission ‘Onward and Upward.’
- The company is building a new launch site in Canada, has signed a cooperation agreement with TKMS, and reports that its launch manifest extends through 2028.
In 2025, the United States had over 190 orbital launches, while Europe had fewer than 10. The main problem is production infrastructure. Right now, Isar Aerospace is the only private European company working on a production system to close this gap.
Founded in 2018 in Munich by Daniel Metzler, Josef Fleischmann, and Markus Brandl as a spinout from the Technical University of Munich, the company has now raised €270 million in Series D funding to expand globally and boost production of its Spectrum launch vehicle.
Island Green Capital and Molten Ventures are new investors, joining HV Capital, Lakestar, UVC Partners, KfW Capital, and others. With this round, Isar Aerospace’s total funding now stands at about €870 million, including earlier equity and debt.
“Space is no longer a frontier; it is the infrastructure of national power. With this strategic backing, we are expanding access to space for nations worldwide, delivering an orbital launch system at scale for government and commercial use customers,” Metzler says.
What are the €270M funds?
Three things are being built in parallel, and all three require capital.
The first is production. Isar’s facility in Parsdorf, near Munich, spans 40,000 square metres and is designed to manufacture up to 40 Spectrum launch vehicles per year, with a high degree of automation and vertical integration. Vehicles three through seven are already in production.
The second is launch infrastructure. Spectrum currently flies from a dedicated complex at Andøya Space in northern Norway, covering polar and sun-synchronous orbits. An agreement with Maritime Launch Services adds Spaceport Nova Scotia in Canada as a second launch site, extending the network to mid- and high-inclination orbits.
The third is the manifest. Isar’s booked launch schedule already extends through 2028, with missions for ESA, NOSA, ElevationSpace, Astroscale, and international commercial customers.
The clearest expression of the defence demand shift is Isar’s cooperation with TKMS, the German naval shipbuilder. The two companies have agreed on an industrial partnership to establish a sovereign Canadian space launch capability as part of TKMS’s bid for the Canadian Patrol Submarine Project, a NATO framework procurement seeking up to 12 conventionally powered submarines.
European competitors include PLD Space, targeting its first orbital launch from Kourou in late 2026, and Rocket Factory Augsburg, developing the RFA ONE launcher for similar small-satellite missions. Both are yet to reach orbit.
Isar’s most recent fundraising context, including a €65M extension from the NATO Innovation Fund in 2024, reflects consistent institutional confidence in the company’s approach.
The rocket that needs to work
The €270 million raises the stakes on a launch window that was already closely watched.
Spectrum’s first flight on March 30, 2025, lasted less than 30 seconds. The rocket cleared the launchpad, making it the first orbital rocket to launch from continental Europe, but it lost control and was shut down by the safety system before falling into the sea.
Isar called it a successful test of the Flight Termination System and a useful data-gathering mission. However, independent observers were less optimistic.
The qualification flight, called Mission ‘Onward and Upward,’ has already been attempted three times. The January 2026 launch was cancelled because of a faulty pressurisation valve. In March, the attempt was stopped when an unauthorised vessel entered the safety zone. The April launch was postponed due to a suspected leak in a pressure vessel.
The window opening on June 15 will be the fourth try. If Spectrum reaches orbit, Isar will become a commercial launch provider. If not, the company will have to explain to its new investors why it has not progressed.
What comes after orbit
If the qualification flight succeeds, Isar’s growth plan is clearer than most launch companies at this stage. The production facility is running, the launch schedule is full, and a second launch site is secured.
Isar is raising money to move into industrial-scale production. Development risk and production-scale risk are distinct challenges, and investors are supporting the move toward larger-scale manufacturing.
Whether Europe can compete with SpaceX in small-satellite launches will depend largely on what happens during the June 15 to 21 launch window at Andøya.
