Another GPS satellite launch has shifted from ULA to SpaceX due to an ongoing investigation into the Vulcan rocket.

US Air Force hands the GPS-III SV08 mission to SpaceX to keep the satellite navigation modernisation timetable on track

The US Air Force has decided to move the next GPS-III satellite launch away from United Launch Alliance’s (ULA) Vulcan rocket and onto SpaceX’s Falcon 9. The change follows an ongoing investigation into technical issues identified after Vulcan’s first flight.

Originally, the GPS-III SV08 mission was due to fly on Vulcan, but delays and the need for further checks prompted the choice of an alternative provider. SpaceX has already demonstrated a track record of successful GPS-III launches and is ready to deliver the mission within the required timeframe.

ULA continues work to address the findings and upgrade the Vulcan rocket, although an exact date for the launcher’s return to flight has not yet been confirmed. Reassigning the launch is intended to prevent disruption to the schedule for refreshing the United States’ navigation satellite constellation.

The US Air Force also notes that diversifying contractors strengthens the resilience of national space programmes and reduces the risks associated with technical delays.
