> United Launch Alliance (ULA) is preparing for the Flight Readiness Firing (FRF) of the Vulcan rocket as a validation of the fully integrated vehicle at Cape Canaveral Space Force Station, Florida.

>FRF demonstrates the day of launch timelines and procedures, propellant loading operations and the entire countdown through ignition of the twin booster engines at Space Launch Complex (SLC)-41.

>The firing will generate a roar of nearly a million pounds of thrust, but Vulcan will remain held to the launch pad by restraining mechanisms. The software program running in the rocket's flight computer will command engine shutdown to complete FRF.

> FRF is one of the most dynamic ground tests performed at the launch site. The team will complete post-abort safing procedures and begin detanking operations following the test.
