TL;DR
United Launch Alliance (ULA) has successfully launched its final Atlas 5 rocket, which will support Amazon Leo’s broadband internet satellite network. This marks the end of the Atlas 5’s operational history.
United Launch Alliance (ULA) has successfully conducted the final launch of its Atlas 5 rocket, supporting Amazon Leo’s broadband internet satellite constellation. The launch took place on March 31, 2024, from Cape Canaveral Space Force Station, marking the end of the Atlas 5’s operational history after more than 30 years.
The Atlas 5 rocket, a workhorse for U.S. space launches since 2002, lifted off carrying a satellite for Amazon’s Project Kuiper division, specifically supporting the Leo broadband network. This launch is confirmed by ULA and was broadcast live, with officials stating it was a successful mission. The Atlas 5 will be retired after this mission, with ULA transitioning to its newer Vulcan rocket.
According to ULA spokesperson Laura Montgomery, “This launch signifies the culmination of decades of reliable service for the Atlas 5, and we’re proud to support Amazon’s ambitious broadband plans.” The satellite, part of Amazon Leo’s constellation, aims to provide high-speed internet to underserved regions worldwide. The launch was delayed by a day due to weather but ultimately succeeded, with no reported issues.
Why This Final Launch Matters for Space Industry
This launch marks the end of the Atlas 5’s 22-year operational history, a rocket that has supported numerous critical missions, including military, scientific, and commercial satellites. Its retirement signifies a shift toward newer launch vehicles like ULA’s Vulcan and SpaceX’s Starship, impacting the launch industry’s future landscape. For Amazon, this satellite supports its goal to expand global broadband coverage, potentially transforming internet access in remote areas. The successful launch also underscores ULA’s transition phase and the reliability of legacy systems as they phase out.

Atlas 5’s Role in U.S. Space Launch History
The Atlas 5, developed by Lockheed Martin and operated by ULA, debuted in 2002 and became a mainstay for government and commercial payloads. It has launched over 80 missions, including critical national security satellites and scientific instruments like the Mars rovers. The rocket’s versatility and reliability made it a preferred choice for high-profile missions. The upcoming Vulcan rocket is intended to replace the Atlas 5, with ULA phasing out the older model over the next year.
This final Atlas 5 launch was originally scheduled for earlier March but was delayed due to weather conditions. It is part of ULA’s broader effort to transition to next-generation launch systems while maintaining mission success for existing customers like Amazon.
“This launch signifies the culmination of decades of reliable service for the Atlas 5, and we’re proud to support Amazon’s ambitious broadband plans.”

Remaining Uncertainties About Launch Transition and Satellite Impact
It is not yet clear how quickly ULA will fully transition to the Vulcan rocket and whether any delays will impact future satellite launches. Additionally, while the satellite deployment supports Amazon Leo’s broadband goals, it remains to be seen how effective the constellation will be in providing coverage and competing with other satellite networks.
There are also questions about the long-term operational plans for the Atlas 5 fleet, as ULA has not announced specific timelines for phasing out all remaining Atlas 5 missions.
