Vulcan Issues to Impact Pentagon’s Next Rocket Competition
▼ Summary
– The US Space Force is responding to the second grounding of ULA’s Vulcan rocket in under two years, which may influence future Pentagon launch service procurement.
– The Vulcan is one of the Space Force’s two primary launch vehicles, alongside SpaceX’s Falcon 9, but has only completed four flights since its 2024 debut despite a large backlog.
– The rocket has experienced two anomalies involving its solid rocket boosters, with an exhaust nozzle blowing off in October 2024.
– A similar booster problem appears to have reoccurred during a Vulcan launch in February of this year.
– In both incidents, the rocket continued its flight and successfully reached the intended orbit.
The reliability of launch vehicles is a paramount concern for the US Space Force, and recent technical issues are directly shaping future procurement strategies. A senior general stated this week that the service is actively assessing the implications of United Launch Alliance’s Vulcan rocket experiencing its second major grounding in under two years. This operational history is expected to be a significant factor in the Pentagon’s upcoming competition for launch services.
As one of the Space Force’s two primary satellite launch providers, alongside SpaceX’s Falcon 9, the Vulcan rocket carries a heavy burden of national security missions. It currently has a manifest backlog approaching 70 launches. However, its operational cadence has been slow, with only four flights completed since its inaugural launch in January 2024. More concerning are the recurring technical problems that have emerged on two of those missions.
Both incidents involved anomalies with the rocket’s solid rocket boosters. The first occurred in October 2024, when an exhaust nozzle detached from a booster during flight. An apparently identical issue manifested again during a Vulcan launch this past February. While the vehicle successfully completed its primary mission and delivered its payload to the intended orbit on both occasions, the repeat failure has triggered a thorough investigation and another stand-down. These persistent solid rocket booster problems are now under intense scrutiny as the Space Force evaluates its long-term launch partnership with ULA.
The service’s analysis of these events will likely influence how it structures future contracts, potentially placing greater emphasis on demonstrated flight heritage and consistent operational availability. This evaluation comes at a critical time as the Pentagon prepares for its next round of launch service acquisitions, where proven reliability may carry more weight than ever before.
