United Launch Alliance (ULA) successfully launched an Atlas 5 rocket on April 27, 2026, at 8:53:30 p.m. EDT from Cape Canaveral Space Force Station. This mission was notable for being the quickest turnaround at this launch pad, completing the operation almost three days faster than the previous record.
The Atlas 5 rocket carried 29 Amazon Leo satellites as part of the Leo Atlas 6 mission, marking ULA’s sixth flight for these broadband internet satellites. This launch follows two demonstration satellites sent into orbit in October 2023.
The recent mission also set a milestone with this being the 108th overall Atlas 5 launch and the 100th under ULA. To enhance efficiency, ULA modified its prelaunch procedures. In contrast to the traditional method of rolling out the rocket a day before launch, ULA rolled the Atlas 5 to the pad on the morning of the launch. This allowed them to save time as the Mobile Launch Platform was lowered into position.
In a bid to streamline operations, two teams worked together to complete tasks that usually take two days. ULA noted that not all future missions would adopt this new schedule, as specific operational factors will influence the timeline.
With this launch, the Amazon Leo satellite constellation now comprises 270 satellites, marking the 10th overall launch for this effort. Ultimately, the initial constellation aims to include over 3,200 satellites.
