Space Force suspends use of ULA’s Vulcan rocket
Space Force officials yesterday made it official, that it has suspended all further military launches using ULA’s Vulcan rocket, due to the nozzle failure in one of the rocket’s solid-fueled strap-on boosters during the last launch on February 12, 2026.
The Space Force is pressing pause on all military launches on United Launch Alliance’s Vulcan rocket as officials investigate a recent anomaly they say could take “many months” to resolve.
That means launch plans for a GPS III satellite slated to fly on the brand new rocket next month are in flux, according to Col. Eric Zarybinsky, program executive officer for assured access to space. “I’m going to look for every flexibility I have to make sure that I can deliver warfighter capability as quickly as possible,” Zarybinsky told reporters at AFA’s Air Warfare Symposium here. “I’ve got a number of tools in my toolkit to do that, but until this anomaly is all over, we will not be launching National Security Space Launch missions on Vulcan.”
Though the rocket was able to get the payload to its proper orbit, despite the problem, this was the second Vulcan launch where a strap-on booster, built by Northrop Grumman, experienced a nozzle failure. In addition, another nozzle failure had occurred during a static fire test in 2025.
Prior to the February launch the Space Force had already shifted two launches from ULA’s Vulcan to SpaceX’s Falcon 9. At the moment ULA has seven military Vulcan launches scheduled for this year. Expect a considerable number to shift to SpaceX.
Blue Origin’s New Glenn rocket might also become an option, but the company must complete two more launches before the Space Force will certify it for national security launches. Considering that company’s slow pace in doing anything, it does not appear it will be able to take advantage of this situation.
ULA meanwhile had hoped to complete 18 to 22 launches in 2026, the majority using Vulcan. This decision by the Space Force likely means the company won’t complete more than five launches this year, most of which using its soon-to-be-retired Atlas-5 rocket.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon or from any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News
