在近年来发生的局部战争和地区冲突中,空中进攻作战发挥了日益重要的作用,取得了十分明显的战果。因而,世界各国在空军建设和作战运用方面,都十分重视加强空中进攻力量和充分发挥肮空兵的进攻特长,把空中进攻作为空军作战运用的重要方式。在这种情况下,对地攻击飞机的发展也就倍受重视。对地攻击飞机大体上可分为两类:一类是战略攻击机,即战略轰炸机;另一类是战役战术攻击机。后者按其遂行的任务又可分为战场遮断/纵深攻击机和近距支援飞机,分别被称为战斗(歼击)轰炸机与攻击机。战斗轰炸机主要用来对战区后方的公路、铁路、桥梁、车站、物资供应站、兵员集结点、军用机场等目标实施攻击和轰炸。目的是切断和削弱敌后方对前线的物资供应和人员补充,从而削 In the local wars and regional conflicts that have taken place in recent years, air offensive operations have played an increasingly important role and achieved very clear results. Therefore, all countries in the world attach great importance to strengthening the offensive capabilities of the air force and giving full play to the offensive capabilities of the air force in the construction and operation of the air force, and use the air attack as an important means of air force operations. Under such circumstances, the development of ground-attack aircraft will also receive much attention. Ground attack aircraft in general can be divided into two categories: one is a strategic attack aircraft, that is, strategic bombers; the other is a campaign tactical attack aircraft. The latter can be divided into battlefield interdiction / depth attack aircraft and close support aircraft according to their mission, which are respectively called combat (fighter) bomber and attack aircraft. Fighter-bombers are mainly used to attack and bomb the targets of highways, railways, bridges, stations, material supply stations, assembly points and military airfields in the rear of the theater. The purpose is to cut off and weaken the front-line supply and personnel replenishment by the enemy rear to cut it
