PARIS — Norway’s Kongsberg and Germany’s Helsing are teaming up to provide Europe with a sovereign satellite constellation for space-based intelligence, surveillance and targeting by the end of the decade, the companies said in a joint statement on Wednesday.

The plan is to deploy a satellite fleet with interconnected communications for defense use by 2029, with Germany’s Hensoldt providing sensor technology and German startup Isar Aerospace the preferred launch parter. Kongsberg and Helsing signed their teaming agreement to speed up the roll out of critical European space capabilities, the companies said.

European leaders increasingly see their dependency on American space-based intelligence as a strategic liability, with the U.S. halt on data sharing with Ukraine earlier this year setting off alarm bells across the continent. Finland’s ICEYE has been one of the most visible beneficiaries, selling at least eight radar satellites this year to European countries seeking a sovereign space capability.

“Sovereign monitoring, intelligence, and targeting are fundamental to credible deterrence,” Kongsberg Defence & Aerospace President Eirik Lie said in the statement. “Communication, oversight and connectivity are key to operate defense assets effectively, and Europe needs full control over these capabilities.”

The cooperation is a response to Europe’s greater need for deterrence and addresses the strategic issue of space-based intelligence, Kongsberg and Helsing said, with the companies citing “key lessons from recent geopolitical events.”

Kongsberg wasn’t immediately able to answer questions on the required investment or how many satellites are planned for the constellation, which countries the partnership is targeting, or who would own the satellites.

The teaming agreement combines Kongsberg’s satellites with Helsing’s artificial-intelligence capabilities, pulling together synthetic aperture radar, electro-optical and radio-frequency data for satellite-image analysis, they said. The companies said they have operational experience in Ukraine, with Helsing AI algorithms used there as well as deployed in orbit for data analysis.

“The war in Ukraine demonstrates that most reliable targeting begins in space,” Helsing co-Chief Executive Officer and co-founder Gundbert Scherf said. “Together with Kongsberg, we will provide crucial integrated space defense systems to ensure Europe wins the fight for sovereignty.”

Hensoldt will provide SAR, electro-optical/infrared and electronic warfare sensors, while Kongsberg Satellite Services will contribute with its ground network to communicate with satellites.

The cooperation will include setting up local satellite production in Germany to create “a self-reliant European defense capability,” the companies said.

With Norway’s satellite expertise and Hensoldt’s sensors, “we can build a resilient space architecture that gives Europe the information advantage it needs,” Hensoldt Chief Executive Officer Oliver Dörre said. “Europe’s security depends on sovereign sensing and intelligence.”
