ULA & Northrop Grumman complete static fire test of Vulcan strap-on booster
As part of its investigation into the loss of a strap-on booster nozzle during the second launch of ULA’s Vulcan rocket in October 2024, ULA and Northrop Grumman on February 13, 2025 successfully completed a static fire test of another strap-on booster.
The test was also apparently done in order to convince the Space Force to certify Vulcan for military launches. The Pentagon originally required Vulcan to complete two launches before certification, something that second launch achieved despite the loss of the nozzle. It has held off that certification however, insisting on more information into the nozzle loss.
The investigation has scrambled ULA’s planned launch schedule. The company had hoped after the second certification launch to fly two Space Force commercial launches before the end of 2024. Both launches were pushed back into 2025, so much so that ULA has been forced to de-stack a Vulcan rocket so it can instead do an Atlas-5 launch first, carrying the first set of Amazon’s Kuiper satellites.
Whether the results of this static fire test will satisfy the military is at present unknown. No details about the test were revealed, other than the companies were studying the results.
Readers!
My annual February birthday fund-raising drive for Behind the Black is now over. Thank you to everyone who donated or subscribed. While not a record-setter, the donations were more than sufficient and slightly above average.
As I have said many times before, I can’t express what it means to me to get such support, especially as no one is required to pay anything to read my work. Thank you all again!
For those readers who like my work here at Behind the Black and haven't contributed so far, please consider donating or subscribing. My analysis of space, politics, and culture, taken from the perspective of an historian, is almost always on the money and ahead of the game. For example, in 2020 I correctly predicted that the COVID panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Every one of those 2020 conclusions has turned out right.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
