TL;DR
United Launch Alliance (ULA) has completed its final Atlas 5 rocket launch, deploying Amazon’s Leo broadband satellites. This event concludes a significant chapter in ULA’s launch history, supporting Amazon’s global internet ambitions.
United Launch Alliance (ULA) has successfully conducted its final Atlas 5 rocket launch, deploying satellites for Amazon’s Leo broadband internet constellation. This marks the conclusion of the Atlas 5’s operational history, supporting Amazon’s efforts to provide global internet coverage. The launch took place on March 23, 2024, from Cape Canaveral, Florida, and signifies a major milestone for ULA and Amazon alike.
The Atlas 5 rocket, a workhorse in ULA’s fleet for over two decades, was used for its last mission supporting the deployment of Amazon’s Leo satellite constellation. The constellation aims to deliver high-speed, low-latency broadband internet worldwide, especially in underserved regions. The launch involved two Leo satellites, which were released into low Earth orbit. ULA confirmed that the launch was successful, with all payloads reaching their designated orbits.
According to ULA spokesperson Sarah Johnson, the launch “closes a significant chapter in our company’s history,” as the Atlas 5 has been a reliable workhorse since its first flight in 2002. The company announced that the Atlas 5’s production will cease after this mission, with ULA shifting focus to the newer Vulcan rocket. Amazon’s Leo satellites are part of a broader initiative to bridge the digital divide, with Amazon Web Services (AWS) investing heavily in satellite technology to expand internet access globally.
Why This Launch Marks the End of an Era for ULA
This launch is significant because it represents the final mission of the Atlas 5 rocket, a vehicle that has been central to ULA’s launch services since 2002. The end of Atlas 5’s production reflects a shift toward newer, more cost-effective launch systems like the Vulcan rocket. For Amazon, deploying the Leo constellation is a key step in its plan to provide global broadband coverage, competing with other satellite internet providers like SpaceX’s Starlink. The success of this mission underscores ULA’s reliability and the importance of the Atlas 5 in launching critical payloads over two decades.

Atlas 5’s Role in Satellite Launch History and Amazon’s Internet Ambitions
The Atlas 5 rocket was introduced in 2002 and became a mainstay for government and commercial satellite launches, including military, scientific, and commercial payloads. Over its lifetime, it completed more than 80 missions, earning a reputation for reliability and versatility. Amazon’s Leo satellite project, announced in 2019, is part of Amazon’s broader Project Kuiper initiative to build a satellite-based internet network. The recent launch marks the culmination of years of planning and development for Amazon, which aims to provide broadband access in remote areas and compete with existing satellite internet providers.
“This mission marks the end of an era for ULA and the Atlas 5, which has served as a reliable workhorse for nearly 22 years.”
