United Launch Alliance Advances Amazon Leo Constellation with Successful Leo 5 Launch

A United Launch Alliance (ULA) Atlas V rocket carrying the Leo 5 mission for Amazon lifted off on April 4 at 1:46 a.m. EDT from Space Launch Complex-41 at Cape Canaveral Space Force Station. This mission demonstrates the strong partnership between ULA and Amazon to accurately and rapidly launch and deliver innovative solutions for global connectivity.

“Connecting the world begins with liftoff and ULA is proud to work collaboratively with Amazon Leo to deliver the next batch of 29 satellites to space,” said Gary Wentz, ULA vice president of Atlas and Vulcan programs. “We have precisely delivered a total of 139 satellites, and each one contributes to Amazon’s overall mission, we understand the importance of populating the Leo constellation and are already working on our next Amazon Leo mission, Leo 6 which will launch on an Atlas V rocket in late April.”

The Amazon Leo 5 launch deployed another batch of operational satellites into low Earth orbit. There are three remaining Amazon Leo missions on the Atlas V rocket, as well as 38 launches on the next-generation Vulcan rocket.

ULA’s next launch is the Atlas V Amazon Leo 6 mission. This launch is planned for April 27, 2026, from Cape Canaveral Space Force Station, Fla., pending range approval.
