United Launch Alliance postponed Vulcan’s first Amazon Leo mission on Friday, November 13, 2026, after a power interruption at Air Liquide’s gaseous nitrogen plant disrupted high-pressure pump operation, the company said. The stated holdup is in the ground supply, not a reported rocket malfunction. Source Source
In its November 13 update, ULA targeted Saturday, November 14, at 12:32:30 p.m. EST (17:32:30 UTC) for the next attempt. ULA plans to launch the mission from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida. Friday’s attempt had been scheduled for 12:54 p.m. EST. Source Source
ULA said it could not confirm a sustained nitrogen supply and opted for the backup opportunity. “The vehicle and spacecraft are healthy,” the company said. A clean bill of health for the rocket, unfortunately, isn’t a substitute for nitrogen. Source
The planned payload is 40 broadband satellites, and ULA says this is the first of 38 planned Vulcan launches for Amazon. Amazon Leo, formerly Project Kuiper, is intended to use an initial constellation of more than 3,000 low-Earth-orbit satellites to provide internet access, including in places underserved by existing networks.
