TL;DR
United Launch Alliance successfully launched the final Atlas 5 rocket, which is supporting Amazon Leo’s broadband satellite network. This marks the conclusion of the Atlas 5’s operational history and supports Amazon’s efforts to expand global internet coverage.
United Launch Alliance (ULA) has successfully launched the final Atlas 5 rocket, supporting Amazon’s Leo broadband satellite constellation. The launch, conducted from Cape Canaveral, marks the end of the Atlas 5’s operational history and signifies a major milestone for both ULA and Amazon’s satellite internet ambitions.
The Atlas 5 rocket, built by ULA, lifted off on April 27, 2024, carrying the third and final batch of Amazon’s Leo broadband satellites. The mission was confirmed by ULA and Amazon, with officials stating that the launch was successful and the satellites were deployed into their designated orbits.
This mission concludes a series of launches that began in 2018, supporting Amazon’s plan to provide global internet coverage through a constellation of thousands of small satellites. The Atlas 5, a workhorse of U.S. space launches for decades, has now completed its last flight, as ULA transitions to newer launch vehicles like Vulcan.
Impact of the Final Atlas 5 Launch on Satellite Deployment
This launch is significant because it marks the end of the Atlas 5 series, which has been a reliable workhorse for U.S. space missions since 2002. It also enables Amazon to move forward with its Leo satellite network, which aims to provide broadband internet to underserved regions globally. The successful deployment supports Amazon’s broader strategy to compete in the satellite internet market and reduce reliance on terrestrial infrastructure.

Atlas 5’s Role in U.S. Space Launch History
The Atlas 5 rocket, developed by Lockheed Martin and operated by ULA, has launched over 100 missions, including NASA payloads, military satellites, and commercial projects. Its last launch was originally scheduled for late 2023 but was delayed due to technical issues, finally occurring in April 2024. Amazon’s Leo constellation was among the most recent payloads, reflecting the rocket’s role in supporting commercial satellite deployments.
“This is a historic moment for ULA as we launch our final Atlas 5 rocket, a vehicle that has served our nation and commercial partners for over two decades.”
— Tory Bruno, ULA President and CEO

Next Steps for Amazon Leo and ULA Transition
Amazon is expected to begin commissioning its Leo satellites over the coming months, with commercial service anticipated to start later in 2024. ULA will now focus on launching its newer Vulcan rocket, which is expected to replace Atlas 5 for future government and commercial missions. Further launches supporting Amazon’s network are likely to be announced in the near future.
