Vulcan

Vulcan suffered a significant performance anomaly in one of its four solid rocket motors shortly after launch.

United Launch Alliance will conduct an investigation before the next Vulcan launch.

The Vulcan booster and Centaur upper stage performed nominally and delivered the spacecraft directly to the intended orbit despite the Cert-2 SRB anomaly.

One of Vulcan’s solid rocket booster nozzles detached at approximately T+1:06 during the observed flight.

The Vulcan booster and Centaur delivered the spacecraft directly to geosynchronous orbit despite the solid rocket motor anomaly.

One solid rocket booster on the Vulcan USSF-87 launch appeared to suffer an anomaly similar to the Cert-2 anomaly in October 2024.

A burnthrough on a Vulcan launch was observed at T+0:29 and the full SRB nozzle detached at T+1:06 in the provided launch video.

United Launch Alliance’s Vulcan rocket delivered USSF-87 to geosynchronous orbit.

The Vulcan rocket delivered the satellite to its intended orbit.

Roughly 20 seconds after liftoff on the USSF-87 mission, at least one of the Vulcan rocket's solid rocket booster nozzles showed signs of a possible burn-through.

The Vulcan launch vehicle rolled during ascent to orbit.

Observers identified a potential SRB anomaly during the ULA Vulcan launch.

United Launch Alliance's Vulcan rocket lifted off on the USSF-87 mission.

United Launch Alliance’s Vulcan rocket is on the launch pad for the USSF-87 mission that will place U.S. national security spacecraft into geosynchronous orbit.

Liftoff for the USSF-87 Vulcan mission is scheduled for Thursday at 3:30 a.m. EST (0830 UTC) from Space Launch Complex-41 at Cape Canaveral.

United Launch Alliance is planning a rapid cadence of Vulcan launches following USSF-87.

Issues on Vulcan’s recent flight require review before Vulcan will carry its next national security payload.

The Ariane 64 and United Launch Alliance’s Vulcan rockets both completed their recent missions successfully.
