Vulcan

United Launch Alliance is beginning to stack the next Vulcan rocket while an SRB investigation continues.

Vulcan can carry 5 BlueBird satellites.

The next Vulcan rocket will be Amazon Leo LV-01 and will be the first Vulcan mission to use six solid rocket boosters and a LEO Centaur V upper stage.

AST SpaceMobile mentioned Vulcan among its launch vehicles during its last earnings release.

Preparation is continuing for Leo Vulcan 1 (LV-01), the first of 38 Leo missions on Vulcan Centaur.

Leo satellites are already stacked for LV-01 and future Vulcan launches.

ULA’s Vulcan rocket and Blue Origin’s New Glenn rocket are currently grounded.

Several GPS III satellite launches were moved from Vulcan to Falcon 9 بسبب delays.

Vulcan was planned to launch several GPS III satellites.

Block IIIF is scheduled to start launching next year on Vulcan.

The U.S. Space Force reassigned the final GPS III satellite launch, SV-10, from United Launch Alliance’s Vulcan rocket to a SpaceX Falcon 9 in late March 2026.

Ongoing investigations into Vulcan booster anomalies prompted the U.S. Space Force to move GPS III launch SV-10 from ULA’s Vulcan to SpaceX Falcon 9.

Three Amazon Leo missions remain on the Atlas V rocket, and 38 launches remain on the next-generation Vulcan rocket.

Amazon Leo’s launch lineup includes Falcon 9, Atlas V, Ariane 6, Vulcan, and New Glenn.

The U.S. Space Force is weighing launch alternatives as Vulcan faces a potential months-long grounding.

Amazon Leo’s Ariane 6 launch configuration carries 32+ satellites, Vulcan carries 40+ satellites, and New Glenn carries 48+ satellites.

Problems with ULA's Vulcan rocket could affect Space Force missions including Next-Gen GEO, Silent Barker, WGS, some NRO satellites, and some space domain awareness satellites.

United Launch Alliance has doubled payload processing infrastructure at its Eastern launch site and will bring its West Coast launch site online later in the year with modifications to support Vulcan.
