The PLAAF designations for its general-purpose bombs normally consists the bomb’s normal weight in kilograms followed by a single digit to tell the different series/generations. The first-generation general-purpose bombs introduced in the 1950s/60s were based on the Soviet FAB 1946 series high-drag bombs. They were available in two sizes: 250kg (250-1) and 500kg (500-1). These bombs are no longer in service today.

PLAAF为它的普通用途炸弹命名通常由标准重量公斤数后面是一个表明不同的系列/代的单独数字组成。第一代普通-用途炸弹在1950年/60年制造以苏联FAB 1946系列高阻炸弹为基础。他们可供使用二种尺寸：250公斤（250-1）和500公斤（500-1）。这些炸弹目前不在服役中。

The second-generation bombs were developed in the late 1960s based on the Soviet FAB 1954 series high-drag bombs. They are available in four sizes: 250kg (250-2), 500kg (500-2), 1,500kg (1500-2), and 3,000kg (3000-2). Like their Soviet prototypes, these bombs feature circular ring airfoils for improved ballistic characteristics at supersonic speed. This series can only be carried by the H-6 medium bomber and Q-5 attacker in their internal bomb bays.
第二代炸弹在1960年后期发展以苏联FAB1954系列高阻炸弹为基础。它们可供使用四种尺寸：250公斤（250-2）、500公斤（500-2）、1,500公斤（1500-2）和3,000公斤（3000-2）。像他们的苏联原型，这些炸弹为在超音速改良弹道特性以圆环翼面为特点。这系列只能被H-6中型轰炸机轰炸机和Q-5攻击机在它们的内炸弹舱携带。

In the early 1990s a new series of streamlined, low-drag general-purpose (LDGP) bombs was introduced, designed for external carriage by fighter-bomber aircraft rather than in internal bays. They come in three sizes: 250kg (250-3), 500kg (500-3), and 1,000kg (1000-3). They have Western-style stabilising fins at tail and a single nose fuse. Each size of the bomb could be fitted with different types of warheads (blast, incendiary, anti-armour, etc) for specific combat requirements. They can be equipped by every fighter aircraft in current service with the PLA. 

在1990年早期中一种流线型的新系列，低阻普通-用途（LDGP）炸弹被推出，设计用于被战斗轰炸机在外部携带而不是在内舱中。它们可供使用三种尺寸：250公斤（250-3）、500公斤（500-3）和1,000公斤（1000-3）。它们在尾部有一个西方风格的稳定翼和一个单独的弹头引信。炸弹的每个尺寸可能为特定的战斗需求配备有不同类型的弹头（爆炸、燃烧、反装甲等）。它们能被PLA目前服役的所有战斗机装备。 

 

Later the PLAAF also introduced the fourth series general bombs, which are retarded LDGP bombs fitted with a high drag tail assembly for low-altitude attacks. These bombs are almost identical to the third series bombs apart from the tail assembly, which provides a high speed, low altitude delivery capability by quickly slowing the bomb and allowing the aircraft to escape the blast pattern. This series of bombs are also available in three sizes: 250kg (250-4), 500kg (500-4) and 1,000kg (1000-4).

稍后PLAAF也推出了第四代普通-用途炸弹，是为低高度攻击装有一个高阻尾翼的减速LDGP炸弹。这些炸弹除了尾翼外和第三代系列炸弹相同，被快速减慢的炸弹提供一个高速度、低高度投放能力和允许飞机逃脱爆炸模式。这个系列炸弹也可供使用三种尺寸：250公斤（250-4）、500公斤（500-4）和1,000公斤（1000-4）。
