Isar Aerospace and RFA secure fresh funding: ESA backs Europe’s launch push

In June and August 2026, two of Europe’s most closely watched launch startups, Isar Aerospace and Rocket Factory Augsburg (RFA), picked up new funding and backing from the European Space Agency (ESA). That gives Europe’s push for sovereign launch access some real weight.

Isar Aerospace said in June 2026 that it had raised €270 million in a Series D from new investors Island Green Capital and Molten Ventures, with HV Capital, Lakestar, and UVC Partners also taking part. That brings its total funding to about €870 million and gives the company more room to scale Spectrum rocket production toward 40 rockets a year.

RFA’s position looks stronger too. KKR invested €30 million in August 2023, OHB completed a capital increase that Rocket Factory Augsburg announced in June 2026, and ESA awarded the company a €186.9 million European Launcher Challenge contract in August 2026.

ESA also selected Isar Aerospace and Spain’s PLD Space. Private investors and public institutions are both putting money behind a tougher, more resilient European launch market after years of relying on established providers outside Europe.

If you follow Europe’s launch sector closely, this is one to watch. The real test, though, is still getting to orbit and doing it reliably.

The next markers to watch are Isar Aerospace’s next Spectrum flight from Andoya in Norway, its planned second site in Nova Scotia, and Rocket Factory Augsburg’s inaugural RFA ONE launch from SaxaVord Spaceport in Scotland.
