The U.S. Space Force is once again shifting a national security payload to SpaceX, this time reassigning the GPS III SV10 satellite to a Falcon 9 rocket launch slated for late April. The move comes after continued delays and an ongoing investigation into an anomaly experienced during the inaugural launch of United Launch Alliance’s (ULA) new Vulcan Centaur rocket in January. This latest development underscores a growing reliance on SpaceX for critical space access, even as ULA struggles to deliver on its substantial backlog of military contracts.
The GPS III SV10 satellite, weighing over four tons, is a vital component of the U.S. Military’s global positioning system. Its transfer to SpaceX highlights the Space Force’s priority of maintaining a consistent cadence for deploying these advanced capabilities. According to Space Systems Command, the decision allows for “rapid delivery of advanced GPS capability while the Vulcan anomaly investigation continues,” demonstrating a commitment to “responsive and reliable launch for the nation.”

A Shift in the Balance of Power
This isn’t the first time the Space Force has turned to SpaceX to fill a gap left by ULA. The trend reflects a significant shift in the landscape of U.S. Space launch capabilities. For decades, ULA, a joint venture between Lockheed Martin and Boeing, was the sole provider of launch services for the military, relying on its Atlas V and Delta IV rockets. However, SpaceX disrupted the market by offering significantly lower costs and a faster turnaround time with its reusable Falcon 9 rocket.
SpaceX began launching national security missions in 2018, after successfully challenging the Air Force’s initial decision to award ULA a multibillion-dollar sole-source contract. The company argued the lack of competition stifled innovation and drove up costs. A lawsuit filed by SpaceX in 2014 ultimately led to an opening of the launch market. SpaceNews reported in 2020 that the military selected ULA for 60 percent and SpaceX for 40 percent of missions through the end of 2023.
More recently, SpaceX has solidified its dominance. In April 2023, Space Systems Command announced SpaceX had won the majority of launch contracts through the end of the decade, with ULA taking a secondary role and Blue Origin being added as a third provider. This outcome underscores the growing confidence in SpaceX’s reliability and cost-effectiveness.
Vulcan’s Troubled Debut and the Need for Assured Access
The current situation stems from an anomaly experienced during the first launch of ULA’s Vulcan Centaur rocket on January 8, 2024. While the rocket successfully delivered payloads to orbit, the upper stage failed to achieve its intended orbit, prompting an investigation. The Space Force requires “assured access to space,” a policy established in the 1990s following a series of launch failures that resulted in the loss of critical military payloads. This policy necessitates having multiple, reliable launch providers to mitigate risk and ensure continued access to space-based assets.
The Delta IV rocket, previously a mainstay of U.S. Military launches, has been retired, and the Atlas V is nearing the end of its service life. This leaves SpaceX’s Falcon 9 and Falcon Heavy, along with ULA’s Vulcan, as the only rockets currently certified to launch the heaviest national security payloads. SpaceX’s ability to rapidly reuse its boosters gives it a significant advantage in terms of launch cadence and responsiveness. Each GPS III satellite requires a heavy-lift launch vehicle capable of delivering more than four tons to orbit.
The backlog of military launch contracts held by ULA currently exceeds $8 billion, but the company’s ability to fulfill those contracts is increasingly dependent on resolving the issues with the Vulcan rocket and demonstrating consistent reliability. The Space Force’s decision to transfer the GPS III SV10 launch to SpaceX is a clear signal of the importance of maintaining mission timelines and minimizing disruption to critical space-based capabilities.
Looking Ahead
The Space Force is continuing to investigate the anomaly experienced during the first Vulcan launch, and ULA is working to implement corrective actions. The next scheduled launch for Vulcan is currently planned for later this year, but the timeline remains contingent on the outcome of the investigation. In the meantime, SpaceX will continue to play a crucial role in ensuring the timely deployment of essential national security payloads. The Space Force has not provided a specific date for the next update on the Vulcan investigation, but officials have indicated they will provide further details as they become available.
