Name one of the major components of a ship’s propulsion system.

A major component of a ship's propulsion system is the gas turbine engine. Gas turbine engines are widely used in naval vessels due to their high power-to-weight ratio and efficiency at higher speeds. These engines operate on the principle of converting energy from fuel into mechanical energy through the combustion process, which drives the turbines that, in turn, propel the ship.

Moreover, gas turbine engines are often favored for their ability to reach fast acceleration and high speeds, making them suitable for many types of naval operations, from surface combatants to auxiliary vessels. They are also capable of operating on various fuels, enhancing their versatility in different settings.

While other propulsion systems such as diesel engines and steam engines do play significant roles in maritime propulsion, gas turbine engines represent modern advancements in naval technology, specifically designed for high-performance requirements.
