Vulcan failed to deliver 40 Amazon Leo satellites to orbit on Sunday after an anomaly roughly 10 minutes after liftoff from Cape Canaveral. ULA said the payload did not reach orbit. For Amazon, the immediate consequence is clear: the mission carried its largest-ever batch of internet-constellation satellites.
The failure is a tangible setback for Amazon Leo’s deployment, but it does not yet establish the fate of the wider programme. ULA, the Boeing-Lockheed Martin joint venture, said it did not yet have data on the cause. Amazon Leo said on X that every launch carries risk, particularly an inaugural mission, and described ULA as a trusted partner. That is a corporate response, not a technical account of what went wrong.
The deployment stakes are substantial. Amazon has bought 38 launches from ULA, and Vulcan is intended eventually to carry nearly half of the first generation of Amazon Leo, planned at 3,232 satellites. Amazon had launched about 400 satellites since April 2025 and had not launched since July, according to Le Figaro with AFP. The loss of 40 satellites therefore removes an especially significant mission from the rollout schedule, even though the supplied reporting does not establish a revised timetable.
Vulcan’s recent record makes the investigation consequential. Le Figaro reports that the US military’s space component suspended use of the rocket for its missions after a booster failure during a February launch, the second such failure in four flights. The key question is now the cause of Sunday’s anomaly, before broader conclusions are drawn about the launches Amazon has purchased.
Amazon has alternative launch routes, but they do not erase this interruption. Ariane 6 was scheduled to launch 36 Amazon Leo satellites from Kourou no earlier than 23 November, while Blue Origin’s New Glenn remained grounded after a vehicle exploded during a May test. ULA’s eventual technical explanation, and any effect on Vulcan’s return to flight, will determine how serious this setback becomes.
