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。

The size of the airframe, and its evident focus on supersonic persistence, suggests at a minimum an intention to provide a long range interceptor for air control in the Second Island Chain geography.

新机的大小以及它在超音速续航性上的明显关注，至少暗示了提供一种具备争夺第二岛链制空权能力的长间隔截击机的意图。

By means of block structure grid and second-order zonal solver method, the research on supersonic inlet performance of solid rocket ramjet assisted range projectiles was carried out.

采用块结构网格与二阶精度流场分区求解技术，对固体火箭冲压发动机增程弹丸超声速进气道特性进行了深入研究。

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.

These include: eight sophisticated diesel submarines, advanced SU-30 fighter aircraft, modern air-to-air and air-to-surface weapons, supersonic anti-ship cruise missiles and as many as 350 short- and medium-range ballistic missiles.
