The classification is based on SPECS given from the builder companies and official military websites.The weapons chosen are purely cruise missiles that can solve both anti-ship / land-attack roles and that can be launched from more sources like ship,land,submarine,air or else.
The main criteria taken into consideration are the Max Speed, range, warhead power, cruise speed, versatility, target detection systems, design, precision and so on.
A cruise missile is a guided missile, the major portion of whose flight path to its target (a land-based or sea-based target) is conducted at approximately constant velocity; that relies on the dynamic reaction of air for lift, and upon propulsion forces to balance drag. Cruise missiles are designed to deliver a large warhead over long distances with high accuracy. Modern cruise missiles can travel at supersonic or high subsonic speeds, are self-navigating, and can fly on a non-ballistic, extremely low altitude trajectory. In 2011, it was estimated that a single Tomahawk cruise missile costs US$1,410,000.
