Name two primary propulsion types used on modern surface ships.

• A. Steam turbines and electric motors.
• B. Nuclear reactors and diesel engines.
• C. Hydraulic propulsion and steam engines.
• D. Gas turbine engines and diesel engines.

Answer: (D)

Two main propulsion sources are used on most modern surface ships: gas turbine engines and diesel engines. Gas turbines deliver high power and quick throttle response, which is ideal for pursuing high speeds and rapid maneuvering. Diesel engines, on the other hand, are fuel-efficient and reliable for long-range cruising and economical operations. Together, they’re often arranged in configurations like CODAG, CODOG, or CODLAG, allowing the ship to switch between or blend fast, high-power modes and efficient, steady-speed modes depending on the mission. While nuclear propulsion exists for some specialized ships, it isn’t the typical pairing across modern surface ships, and old steam or hydraulic systems aren’t the standard two primary propulsion types today.
