Before President John F. Kennedy publicly announces the Soviet buildup of offensive intermediate range missiles in Cuba, Strategic Air Command goes on actual airborne alert. B-52 crews are sent on 24-hour flights, fully armed, to areas within striking distance of possible enemy targets. These highly classified flights, which are continued until 1968, are called “Chrome Dome” missions.
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.
