当飞机作为军事武器在第一次大战中使用后,相应的地面防空武器也随之出现,早期的飞机速度较慢且只有低空飞行能力。最初的地面防空武器是发射弹丸的轻武器。随着飞机飞行高度的提高,特别是将飞机用于轰炸飞行后,防空武器也发展成能发射爆破弹头的大口径火炮。早期使用的触发引信不久便为机械定时引信所取 When the aircraft was used as a military weapon in World War I, the corresponding ground air defense weapon also appeared. Early aircraft were slower and had only low-altitude capability. The first ground-based air defense weapon was a firearm that fired projectiles. As the flight altitude increased, especially after the aircraft was used in bombing, the air defense weapon also developed into a large-caliber artillery capable of launching a blasting warhead. Early use of the trigger fuze will soon be taken for the mechanical timing fuze
