Therefore, the number of warheads and projectiles is generally not exactly equal.
The production of warheads, especially nuclear warheads, is strictly restricted by international conventions, and the production cost is high, so it is impossible to mass produce them, while the projectile body is not. Moreover, for strategic missile forces, the number of nuclear warheads is generally counted internationally, and conventional warheads are rarely counted.
In addition, the missile body can carry multiple warheads, including cluster multiple warheads, split-guided multiple warheads and full-guided multiple warheads.
