United Launch Alliance (ULA) has successfully launched its final Atlas 5 rocket, which is supporting Amazon’s Leo broadband satellite project. This marks the end of the Atlas 5’s operational history and a key milestone for Amazon’s satellite plans.
United Launch Alliance (ULA) has successfully launched its final Atlas 5 rocket, which is supporting Amazon’s Leo broadband satellite constellation. This event marks the end of the Atlas 5’s operational history and is a significant milestone for Amazon’s satellite deployment efforts.
The Atlas 5 rocket, built by ULA, lifted off from Cape Canaveral Space Force Station on September 27, 2023. It carried a payload for Amazon’s Project Kuiper, specifically supporting the company’s Leo satellite constellation aimed at providing global broadband internet services.
This launch is confirmed as the final Atlas 5 mission supporting Amazon Leo, with ULA stating that the rocket’s production has officially concluded after this flight. The mission underscores the continued reliance on Atlas 5 for critical satellite deployments, despite the company’s transition to newer launch vehicles.
Why the Final Atlas 5 Launch Matters for Satellite Launching
This launch signifies the end of the Atlas 5’s operational service, which has been a mainstay for U.S. space launches since 2002. It also marks a pivotal moment for Amazon’s satellite plans, as the Leo constellation is a cornerstone of its global broadband ambitions. The successful deployment demonstrates the continued importance of reliable launch vehicles for large-scale satellite networks and signals a shift toward newer rockets like ULA’s Vulcan.

Background on Atlas 5 and Amazon Leo Satellite Deployment
The Atlas 5 rocket, developed by ULA, has supported numerous high-profile satellite missions since its debut in 2002. It has been a workhorse for government and commercial payloads, including NASA missions and military satellites.
Amazon’s Leo satellite constellation aims to provide high-speed internet worldwide, especially in underserved regions. The project, part of Amazon’s broader Project Kuiper, involves deploying over 3,000 satellites in low Earth orbit. The recent launch is the latest in a series supporting this initiative, which has been progressing since 2019.
“This launch marks the end of an era for Atlas 5, which has served us and our customers well for over two decades. Supporting Amazon’s Leo constellation underscores the rocket’s reliability and importance.”
