President Lyndon B. Johnson announces the existence of the Lockheed A-11, with a cruising speed of more than Mach 3 at altitudes above 70,000 feet. (Use of the designation A-11 to refer to the Air Force’s YF-12A was deliberate to cloud the existence of the CIA’s A-12, a single-seat reconnaissance aircraft that had been flying in secret and was the actual basis for the two-seat YF-12.) Only three YF-12A interceptors are built, and the SR-71 program for the Air Force takes precedence.
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.
