装有两个或两个以上子弹头的导弹弹头。一般由母弹头舱、子弹头、释放机构和推进、制导等装置组成。按弹头有无制导装置分，有集束式多弹头、分导式多弹头、全导式多弹头和机动式多弹头。多弹头可提高弹头的突防能力和摧毁目标的能力。
由于与美国相比，俄罗斯更倚重于多弹头分导再入飞行设备，俄罗斯不得不建造相当数量的单弹头导弹来重新获得与美国的势均力敌，而他们没有钱来做到这点。
Since Russia relied more heavily than the United States on MIRVs, the Russians would have to build a considerable number of single-warhead missiles to regain parity, and they couldn’t afford to do it.
更需要指出的是，运载火箭整流罩的设计技术与导弹多弹头整流罩设计技术存在显著的不同。
What deserves special mention is that a distinct difference exists between the design technology of the fairing on a carrier rocket and that of a multiple-warhead missile.
