For transonic free stream, sudden performance degradation occurs. For the further supersonic range, performance losses increase slightly with increasing Mach number.

在继续的超声速范围内，性能损失随外流马赫数增加只有小幅增长。

Artillery was gradually replaced by tactical missiles in the defensive role, but the Air Force was too busy building a fleet of long-range bombers and supersonic fighters to be bothered with ground-based air defenses, while Army troops had a clear need for such defenses.
