United Launch Alliance Enables Expansion of Amazon Leo Constellation through Fourth Successful Launch

A United Launch Alliance (ULA) Atlas V rocket carrying the Leo 4 mission for Amazon lifted off on Dec. 16 at 3:28 a.m. EST 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 innovation solutions for global connectivity.

“One of our primary missions at ULA is to be a catalyst in connecting the world,” said Gary Wentz, ULA vice president of Atlas and Vulcan programs. “Partnering with Amazon contributes to their mission of bridging the global digital gap. We thank the Amazon Leo team for their continued collaboration.”

The Amazon Leo 4 launch deployed another batch of operational satellites into low Earth orbit. There are multiple remaining Amazon Leo missions on the Atlas V rocket, as well as 38 high-cadence, rapid fire launches on the next-generation Vulcan rocket. Through the world’s largest commercial launch agreement, ULA will deliver more than half of Amazon’s initial constellation 3,000 plus satellites.
