SpaceX Accuses Amazon of Kuiper Orbit Violations

SpaceX has accused Amazon of endangering other satellites by deploying its broadband constellation into higher-than-authorized orbits, prompting Amazon to deny any violations and pledge adjustments to its launch plans.

In letters filed with the Federal Communications Commission this week, SpaceX alleged that Amazon's Project Kuiper, now known as Amazon Leo, has conducted eight launches placing satellites 50 to 90 kilometers above the 400-kilometer initial altitude specified in its FCC license. The company highlighted a February 12, 2026, launch of 32 satellites aboard an Arianespace Ariane 6 rocket, which it said created unmitigable collision risks near the 480-kilometer altitude. According to SpaceX, Amazon and Arianespace failed to provide adequate coordination or predicted orbital data, forcing 30 Starlink satellites to perform emergency avoidance maneuvers within hours of the deployment. "Amazon's unapproved action materially altered the collision risk profile the Commission evaluated," SpaceX wrote, arguing that the practices heighten threats to operational spacecraft and space-based services relied on by millions.

Amazon responded in a filing on April 2, rejecting the...
