Iridium Absorbs Aireon in $367 Million Deal Ahead of Rocket Lab Sale

Iridium Communications has completed its takeover of Aireon, the aircraft-tracking venture, buying the remaining 61 percent it did not already own for $367 million. The move brings the aviation safety service fully in-house ahead of Iridium's planned $8 billion sale to Rocket Lab.

Iridium announced the completed purchase on July 6, acquiring Aireon shares from air navigation service providers in Canada, England, Denmark, Ireland and Italy. Aireon has provided an aviation safety service since 2019, using Iridium satellites and the Automatic Dependent Surveillance-Broadcast signals that aircraft transmit. It will continue to operate as a wholly owned subsidiary.

The transaction comes as Rocket Lab, based in Long Beach, California, prepares to acquire Iridium. Rocket Lab has said it intends to use Iridium's connectivity constellation, L-band spectrum and services to expand into new areas, though it has not detailed specific plans for Aireon.

Iridium CEO Matt Desch framed the deal as the culmination of a long effort. "What began as a bold vision more than a decade ago has become a foundational capability for global air traffic management, delivering real-time surveillance and operational intelligence on a truly global scale," he said. "Together, we will continue investing in the technologies and innovations that we believe will make aviation safer, more efficient, and more resilient for decades to come."

That work includes a space-based VHF system that would use radio equipment already on aircraft to extend pilot-to-controller voice and data communications into oceanic and remote airspace.

Rocket Lab CEO Peter Beck signaled ambitions for the acquired business last week after announcing the plan to buy Iridium. "We're not just going to acquire this business," Beck said. "We are going to apply the Rocket Lab magic to it. We're going to absorb it and optimize it and scale it into something really truly fantastic."

Aireon CEO Don Thoma, who is staying on following the deal, told employees in a June 29 email that Rocket Lab views the venture as central to the aviation growth strategy built around surveillance, communications and resilient positioning, navigation and timing services. "Aireon has been, and continues to be, an important part of the Iridium journey and will be central to the continued growth strategy," Thoma wrote. "Rocket Lab recognized this, viewing Aireon as a key driver of the unique mission critical capabilities Iridium provides to the aviation industry, specifically to the opportunities unlocked through the acquisition of Aireon."

By naming Aireon a key driver of Iridium's aviation capabilities and confirming Thoma's continued leadership, both companies frame the venture as core to the growth strategy Rocket Lab is buying into. Desch tied the deal directly to continued investment in aviation safety and efficiency technologies.

Rocket Lab expects to close its acquisition of Iridium in mid-2027, subject to regulatory clearances and approval from Iridium's shareholders.
