Questions tagged [missiles]

In modern military usage, a missile, or guided missile, is a self-propelled precision-guided munition system, as opposed to an unguided self-propelled munition, referred to as a rocket. All known existing missiles are designed to be propelled during powered flight by chemical reactions inside a rocket engine, jet engine, or other type of engine.
