Space Force Pauses Vulcan Launches: A Deep Dive into the Anomaly and What It Means for National Security Space Access
The U.S. Space Force has temporarily halted all national security launches utilizing United Launch Alliance’s (ULA) Vulcan Centaur rocket following a recurring anomaly with its solid rocket boosters. This decision, announced on February 25, 2026, comes after the issue surfaced on both the January 2024 debut launch and the more recent USSF-87 mission on February 12, 2026. While the rocket’s core engines have compensated, ensuring mission success thus far, the Space Force is prioritizing a thorough investigation before resuming critical national security payloads.
The Recurring Booster Issue: What Happened?
The problem centers around anomalies detected in the solid rocket boosters shortly after liftoff. During the February 12th USSF-87 launch, carrying two reconnaissance satellites for the Geosynchronous Space Situational Awareness Program (GSSAP), a visible anomaly occurred approximately 20 seconds into flight. A similar issue was observed during the October 2024 national security payload certification launch, attributed to a manufacturing defect in a booster nozzle. The exact nature of the February 12th anomaly is still under investigation by ULA.
Impact on National Security Space Launch Capabilities
This pause represents a significant disruption. ULA has contracts for over two dozen national security launches in the coming years. The Vulcan Centaur was designed to replace both the Atlas 5 and Delta 4 rockets, representing a crucial component of the U.S.’s strategic space lift capability. The grounding underscores the critical importance of reliability in national security space access.
Beyond the Immediate Pause: Broader Implications for ULA
The timing of this issue is particularly sensitive for ULA. The company recently saw the departure of its longtime CEO, Tory Bruno, who subsequently joined competitor Blue Origin – the very company that manufactures the BE-4 engines powering Vulcan’s first stage. This adds another layer of complexity to the situation as ULA navigates the investigation and corrective actions.
What’s Next for the Vulcan Centaur?
According to Space Force Col. Eric Zarybnisky, resolving the anomaly will be a “many-months process.” ULA is committed to identifying the root cause and implementing corrective measures to prevent future occurrences. The Space Force has made it clear that no further national security missions will proceed until the issue is fully addressed.
The Role of Solid Rocket Boosters in Modern Launch Systems
Solid rocket boosters are frequently used to provide additional thrust during the initial phases of launch, particularly for heavier payloads. They offer a cost-effective solution, but are less controllable than liquid-fueled engines once ignited. The recent Vulcan anomalies highlight the challenges of ensuring consistent performance and reliability in these systems.
FAQ: Vulcan Centaur Launch Pause
