ULA swapping Vulcan for Atlas-5 for first 2025 launch
ULA has decided to destack the Vulcan rocket it had planned as its first launch in 2025 (launching a military payload) and is now replacing it with one of its remaining Atlas-5 rockets to put the first batch of satellites for Amazon’s Kuiper internet constellation.
It appears the military is not ready to certify this launch after the second Vulcan launch in October 2024 experienced a problem with one of its strap-on boosters. The payload got to its proper orbit, but the loss of that booster’s nozzle appears to be an issue the military remains concerned about.
Rather than wait, ULA decided to switch to the Kuiper launch. The company wants to complete up to 20 launches in 2025, many of which are for Amazon using its last ten or so Atlas-5 rockets. When it can start commercial launches of Vulcan remains somewhat uncertain. The military has indicated it will make a final decision of certification in the spring, and has also said that first operational flight will follow soon after.
