How have warship designs changed over the years, and why?

 Warship designs have changed significantly over the years, reflecting the evolution of naval warfare and the technological advances that have shaped the development of military ships. Some of the key ways in which warship designs have changed over the years include:

Weapon systems: Warships have always been designed to carry weapons, and the types and capabilities of these weapons have changed significantly over time. For example, early warships carried cannons that fired iron balls, while modern warships may be equipped with guided missiles, drones, and other advanced weapons systems.

Propulsion systems: Warships have also evolved in terms of their propulsion systems, which determine how they are powered and how they move. Early warships were powered by wind or human muscle, while modern warships may be powered by fossil fuels, nuclear power, or other energy sources.

Armor and protection: Warships have been designed to protect their crews and equipment from enemy attacks, and the methods of protection have changed over time. Early warships used thick wood planking to absorb cannon fire, while modern warships may be equipped with armor plating, electronic countermeasures, and other protective systems.

Size and shape: The size and shape of warships have also changed over time, reflecting advances in construction techniques and the needs of the military. Early warships were relatively small and often shaped like longboats, while modern warships may be much larger and have complex hull shapes
