Means of delivery
Very different means of delivery can be used for nuclear, biological or chemical weapons, such as pieces of artillery, missiles, cruise missiles, aircraft, helicopters or torpedoes. Various systems, such as aircraft with cruise missiles or submarines with torpedoes or cruise missiles can also be combined with each other. Not all systems are suitable for delivering the various kinds of weapons of mass destruction. Long-range ballistic missiles, for instance, are a highly uneconomic means of transport for chemical weapons and are hardly suitable for the use of biological weapons. While pieces of artillery can fire chemical or nuclear weapons in local fights, they are not suitable for nuclear weapons with high explosive power.
