Background on the Vulcan Centaur Rocket
The Vulcan Centaur represents a modern advancement in space transportation. Developed by United Launch Alliance (ULA), a joint venture between Boeing and Lockheed Martin, this rocket replaces older models like the Atlas V and Delta IV. It stands over 200 feet tall and uses innovative engines powered by methane and oxygen. These choices make it more efficient and reusable in parts compared to previous designs. ULA designed the Vulcan to handle a variety of missions, from commercial satellites to national security tasks.
Engineers at ULA spent years testing the rocket’s components. The core stage relies on two BE-4 engines from Blue Origin, while strap-on boosters provide extra power for heavier loads. For certain flights, like the one in question, four solid rocket boosters attach to the main body. These boosters, known as GEM 63XL and made by Northrop Grumman, burn solid fuel to generate immense thrust quickly. The upper stage, called Centaur, uses hydrogen and oxygen for precise orbital insertions. This combination allows the Vulcan to carry payloads to distant orbits, such as geosynchronous ones about 22,000 miles above Earth.
The rocket’s development faced delays due to engine readiness and supply chain issues. Its first flight occurred in January 2024, followed by a second in October that year with a noted booster irregularity. By 2026, the Vulcan had become a key player in the U.S. launch market, competing with vehicles from SpaceX and others. Missions for the United States Space Force highlight its role in supporting military operations, including communication and surveillance from space. The February 12 launch, designated USSF-87, aimed to place classified satellites into orbit, underscoring the rocket’s importance for national defense.
Details of the February 12 Launch
The launch took place at Space Launch Complex 41 in Cape Canaveral Space Force Station, Florida. Liftoff happened at 4:22 a.m. Eastern Standard Time on February 12, 2026. Weather conditions were favorable, with clear skies allowing spectators and cameras to capture the event. The rocket configuration, VC4S, included the core stage, four solid rocket boosters, and the Centaur upper stage. Payloads consisted of multiple classified items for the Space Force, including surveillance satellites and smaller experiments.
As the countdown reached zero, the BE-4 engines ignited first, followed by the boosters. The rocket ascended steadily, producing a bright plume against the dark sky. Onlookers noted the typical roar and vibration associated with such events. Live streams from ULA showed the vehicle climbing through the atmosphere, with telemetry data indicating normal performance in the initial seconds. Separation events were planned meticulously, with boosters detaching after about 90 seconds and the core stage continuing until around five minutes into flight.
The mission’s objective was direct insertion into geosynchronous orbit. This path requires precise timing and power to position satellites where they can hover over specific Earth locations. ULA’s team monitored the flight from a control center, ready to respond to any deviations. Post-launch, the company confirmed the payloads reached their intended positions, marking the flight as successful overall. This outcome demonstrated the rocket’s robustness, even under unexpected conditions.
Description of the Anomaly
About 20 seconds after liftoff, an irregularity appeared in one of the four GEM 63XL boosters. Video footage revealed a sideways jet of flame emerging from the nozzle area. This indicated a burn-through, where hot gases escaped through an unintended path in the nozzle structure. Sparks and debris followed, visible as bright streaks trailing the rocket. The affected booster continued to operate, but with reduced efficiency and uneven thrust.
The nozzle’s role is to direct exhaust gases downward for maximum propulsion. When compromised, it can cause the rocket to roll or deviate from its path. In this case, the Vulcan’s guidance system detected the imbalance and adjusted the other engines to compensate. This quick response prevented a major trajectory error. Observers compared the visual effect to a firework malfunction, with material liberating from the booster.
ULA described the event as a significant performance anomaly. It occurred early in the boost phase, before the vehicle reached maximum dynamic pressure. Despite the visible drama, the rocket maintained stability. The boosters separated as scheduled, falling away into the ocean. Analysis of telemetry showed the core stage and Centaur performed without issues, ensuring the payloads’ delivery.
Immediate Aftermath and Mission Impact
Following the launch, ULA’s team began reviewing data from sensors and cameras. They established a recovery effort to collect any debris from the ocean. Initial assessments confirmed no ground damage or safety risks. The anomaly did not prevent orbital insertion, as the rocket’s redundancy features absorbed the loss in thrust. Payload deployment happened nominally, with satellites separating at the correct altitude and velocity.
The Space Force expressed satisfaction with the outcome. Their payloads, designed for long-term operations, entered geosynchronous orbit without complications. This success maintained operational timelines for defense-related activities. However, the incident raised questions about reliability for future missions. ULA paused upcoming launches pending the investigation’s results.
Historical Context of Booster Issues
This was not the first time the Vulcan encountered a booster anomaly. During its second flight in October 2024, a similar nozzle failure occurred. That event involved a manufacturing defect leading to nozzle detachment mid-flight. ULA conducted a thorough review then, implementing reinforcements to prevent recurrence. The 2024 incident also resulted in mission success, thanks to the rocket’s design margins.
Solid rocket boosters have a history in spaceflight. They powered the Space Shuttle for decades, with occasional irregularities like O-ring failures in the Challenger disaster. Modern boosters incorporate advanced materials to withstand extreme temperatures and pressures. Northrop Grumman, the manufacturer, uses carbon fiber composites for strength and lightness. Yet, the intense environment of launch can expose weaknesses in assembly or materials.
The GEM 63XL represents an evolution from earlier models. It provides more thrust than predecessors, enabling heavier payloads. Testing on the ground simulates flight conditions, but real launches reveal unforeseen stresses. ULA and Northrop Grumman collaborated closely after the 2024 event, applying fixes like enhanced inspections. The 2026 anomaly suggests persistent challenges in scaling production or material consistency.
Ongoing Investigation and Corrective Measures
A joint team from ULA, Northrop Grumman, and government agencies leads the investigation. They examine telemetry, high-speed video, and any recovered parts. Root cause analysis focuses on manufacturing processes, such as nozzle bonding or material quality. Simulations recreate the failure to test hypotheses. Findings will guide modifications, possibly including design changes or additional testing.
ULA’s leadership emphasized a data-driven approach. They plan to share results with stakeholders, including the Space Force and commercial clients. Corrective actions might involve supplier audits or process refinements. The goal is to enhance reliability without delaying the launch manifest. Vulcan has several missions lined up, including ones for Amazon’s satellite constellation.
The incident highlights broader industry efforts to improve launch safety. Redundancy in systems, like multiple engines, mitigates single-point failures. Certification processes for national security launches require demonstrated performance. ULA aims to resolve the issue swiftly to maintain trust.
Implications for the Space Industry
Recurring anomalies could affect ULA’s position in the competitive market. Rivals like SpaceX offer reusable rockets with proven track records. Customers weigh cost, schedule, and reliability when selecting providers. The Vulcan’s strengths include its powerful upper stage for direct GEO insertions, a niche capability.
The event underscores the challenges of new rocket development. Transitioning from legacy systems involves risks, but yields long-term benefits. ULA invests in Vulcan to secure future contracts under the National Security Space Launch program. Success in resolving booster issues will bolster confidence.
Broader trends show increasing launch cadence across providers. Government and private sectors demand more access to space for communication, Earth observation, and exploration. Anomalies serve as learning opportunities, driving innovation in materials and engineering.
