After nozzle failure, Space Force is “assessing” impacts to Vulcan schedule
United Launch Alliance has started assembling its next Vulcan rocket-the first destined to launch a US military payload-as the Space Force prepares to certify it to loft the Pentagon's most precious national security satellites.
Space Force officials expect to approve ULA's Vulcan rocket for military missions without requiring another test flight, despite an unusual problem on the rocket's second demonstration flight earlier this month.
ULA has launched two Vulcan test flights. Military officials watched closely, gathering data to formally certify the rocket is reliable enough to launch national security missions. The first test flight in January, designated Cert-1, was nearly flawless. The Cert-2 launch October 4 overcame an anomaly on one of Vulcan's strap-on solid rocket boosters, which lost its exhaust nozzle but kept firing with degraded thrust.
