Remember the Titan: Barring changes to the schedule, the final Titan IV rocket will blast off from its pad at Vandenberg AFB, Calif., Wednesday. Carrying a classified payload for the National Reconnaissance Office, the 20-story Titan is being replaced by a new breed of rockets developed under the Air Force’s Evolved Expendable Launch Vehicle program.
While the Space Force is still making long-term plans to establish high-fidelity live and virtual test and training ranges in the coming years, officials say they're also working with operators to identify near-term gaps and quickly field capabilities to address them.
