TL;DR
United Launch Alliance (ULA) has launched its final Atlas 5 rocket, which is supporting Amazon’s Leo broadband internet satellite project. This marks the end of the Atlas 5’s operational history, a key milestone for ULA and Amazon’s satellite ambitions.
United Launch Alliance (ULA) has successfully launched its final Atlas 5 rocket, which is supporting the deployment of Amazon’s Leo broadband satellite constellation. This event marks the end of the Atlas 5’s operational history after more than 130 launches, and it underscores ULA’s transition to newer launch vehicles. The launch, conducted from Cape Canaveral Space Force Station, was confirmed by ULA officials and was part of Amazon’s ongoing efforts to expand global internet coverage.
The Atlas 5 rocket lifted off on September 27, 2023, carrying Amazon’s Leo satellite as part of the company’s ambitious plan to provide broadband internet worldwide. According to ULA, this was the last flight of the Atlas 5, a workhorse rocket that has been in service since 2002. The mission was successful, with the satellite reaching its designated orbit, as confirmed by ULA and Amazon representatives.
Amazon’s Leo constellation aims to deploy over 3,000 low Earth orbit satellites to deliver high-speed internet to underserved regions globally. The satellite launched today is one of many planned, with Amazon investing billions to support the project, which is part of its broader push into space-based infrastructure.
ULA’s Atlas 5, manufactured by Lockheed Martin, has historically been a reliable vehicle for government and commercial payloads. Its retirement signifies a shift toward newer launch systems like ULA’s Vulcan rocket, which is expected to replace the Atlas 5 in upcoming missions.
Implications for ULA and Amazon’s Satellite Plans
This launch marks a significant milestone for ULA, as it concludes the operational history of the Atlas 5 after over two decades of service. For Amazon, the successful deployment of the Leo satellite demonstrates progress in its broadband ambitions, potentially transforming internet access in remote and underserved areas. The event also signals a transition in launch technology, with ULA moving toward newer vehicles like Vulcan, which may impact future satellite deployment strategies.

Background on Atlas 5 and Amazon Leo Project
The Atlas 5 has been a mainstay in space launches since its first flight in 2002, supporting both government missions and commercial payloads. It is known for its reliability and versatility. Its retirement was announced earlier this year as ULA prepares to transition to the Vulcan rocket, which aims to offer more cost-effective launches.
Amazon’s Leo satellite project was announced in 2019 as part of its broader effort to develop a satellite-based broadband network. The company has invested heavily in the project, with the first satellites launched in 2022. The recent Atlas 5 launch is the final step in deploying the initial phase of this constellation.
This mission also reflects the broader trend of commercial companies taking a leading role in space infrastructure development, alongside traditional government agencies.
“This is a historic moment for ULA as we launch our final Atlas 5 rocket, a vehicle that has served us and our customers reliably for over 20 years.”
— Jim Sponnick, ULA Vice President

Next Steps for ULA and Amazon Satellite Deployment
ULA is expected to continue launching Amazon Leo satellites using its new Vulcan rocket, which is scheduled to enter service in 2024. Amazon will likely announce additional satellite launches to expand its constellation and improve coverage. The company also plans to start commercial service once a substantial number of satellites are operational.

Key Questions
Why is this the final Atlas 5 launch?
ULA announced the retirement of the Atlas 5 earlier this year to transition to its newer, more cost-efficient Vulcan rocket, which is expected to replace it for future missions.
How does Amazon’s Leo satellite constellation differ from other broadband projects?
Amazon’s Leo constellation aims to provide global internet coverage via over 3,000 low Earth orbit satellites, focusing on underserved and remote regions, similar to projects like SpaceX’s Starlink but with different deployment strategies and coverage goals.
When will Amazon’s Leo satellites become operational?
While the first satellites have been launched, Amazon has not disclosed a specific operational date. It is expected to be within the next 1-2 years as the constellation expands and satellites become functional.
What is the significance of the Atlas 5’s retirement?
The Atlas 5’s retirement marks the end of a reliable launch vehicle that has supported U.S. government and commercial missions for over two decades, making way for newer, more versatile launch systems.
