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.
The rate of building B-21 bombers would speed up if the fiscal 2026 defense budget passes. But it remains unclear how much capacity would be added, and whether the Air Force would simply build the bombers faster, or buy more.
