SpaceX's Proposal to Revamp Rocket Launch Spectrum Faces Resistance from Aerospace Group

SpaceX-backed plan to automate spectrum coordination for rocket launches faces opposition from aerospace and defense groups urging caution due to interference risks.

SpaceX is advocating for a significant overhaul of how wireless spectrum is coordinated for rocket launches, seeking to replace the current third-party frequency coordination system with a more direct and automated approach. This proposal, supported by the Commercial Space Federation (CSF), aims to implement near-real-time database coordination across shared telemetry frequency bands used during launches.

Following a Presidential Memorandum issued in August 2026, the Federal Communications Commission (FCC) opened the floor for public comment on modernizing launch spectrum coordination. The CSF petitioned the FCC to shift from the existing flight-test frequency coordination process to a system that allows direct coordination between government and commercial entities, potentially streamlining launch scheduling.

However, this move has prompted pushback from a coalition of aerospace and defense industry stakeholders, including major aircraft manufacturers like Boeing and Lockheed Martin. The Aerospace & Defense Industry Spectrum Coalition submitted formal comments cautioning the FCC about the risks of increased electromagnetic interference that could arise from these changes.

The coalition emphasized that the shared frequency bands are critical for real-time safety telemetry not only during rocket launches but also throughout prototype aircraft evaluations, electric vertical takeoff and landing (eVTOL) certification flights, and defense testing operations. They expressed concerns that the expedited nature of the FCC's review process has not allowed enough time for thorough technical studies to confirm that the new coordination approach would not cause harmful interference.

The FCC is now tasked with balancing the desire to accommodate faster and more frequent rocket launches, as advocated by SpaceX, with the need to protect existing aerospace and defense operations that depend on these frequencies. This dispute highlights the complex management of shared spectrum resources amid growing demand from diverse aerospace activities.

Separately, SpaceX recently achieved a regulatory milestone after the FCC approved its application to deploy 15,000 next-generation satellites for its direct-to-device (D2D) mobile service, branded as Starlink Mobile. Unlike traditional satellite internet offerings that rely on terrestrial cell towers, SpaceX plans to use satellites in tandem with ground-based femtocells to deliver 5G coverage. This approach aims for download speeds around 150Mb/s, significantly higher than current Starlink downlinks provided through partnerships with terrestrial mobile operators.

The FCC granted SpaceX a waiver allowing it to offer mobile service without leases from terrestrial carriers, a move the agency said would increase competition and bring modern connectivity to a broader population. Nonetheless, industry experts remain skeptical about the feasibility of such satellite-to-device 5G technologies.

Overall, SpaceX's dual efforts to modernize spectrum coordination for space launches and revolutionize satellite-based mobile service illustrate the evolving challenges in managing wireless resources amid expanding aerospace and telecommunications ambitions.
