What is the main advantage that a missile has over an artillery shell?

 Missiles and artillery shells are both types of military ordnance that are designed to be launched over long distances and to deliver a payload to a target. However, missiles have several key advantages over artillery shells:

Range: Missiles typically have a much longer range than artillery shells, as they are powered by rocket engines or jet engines and can be guided to their targets. This allows them to strike targets at distances that are beyond the range of most artillery systems.

Accuracy: Missiles can be equipped with guidance systems that allow them to be precisely directed to their targets, whereas artillery shells are generally not as accurate and are affected by factors such as wind and gravity.

Speed: Missiles can travel at much higher speeds than artillery shells, which makes them more difficult to intercept or defend against.

Payload: Missiles can carry a wider variety of payloads than artillery shells, including explosives, chemical or biological agents, and nuclear weapons.

Versatility: Missiles can be launched from a variety of platforms, including ships, planes, and ground-based launchers, which gives them a high degree of versatility in terms of how they can be employed.
