50年代防空导弹的普及,极大地冲击了野战高射炮的发展。一些发达国家的地面防空系统甚至淘汰了高炮系统,转而向全面导弹化发展。可是,嗣后的战争表明:为降低防空导弹的威胁,空中目标在攻击中一改昔日的高空高速突防的战术,针对雷达的低空盲区和防空导弹的弱点,采取低空突防的战术实施近距离低空突袭(图1)。因此高炮,特别是小口径高炮,以其射速高、初速大机动灵活、射击准备时间短、抗 The popularity of the 50’s air defense missiles has greatly affected the development of field anti-aircraft guns. In some developed countries, the ground air defense system even eliminated the antiaircraft artillery system and turned to full missile development. However, the ensuing war shows that in order to reduce the threat of anti-aircraft missiles, the air target has changed the tactics of the old high-altitude and high-speed penetration in the attack and adopted the tactics of low-altitude penetration to implement the short-range Low-altitude raid (Figure 1). Therefore, anti-aircraft guns, especially small-caliber anti-aircraft guns, are characterized by their high-speed fire, high-speed maneuvering, short shooting preparation time,
