What type of propulsion does the FREEDOM variant (LCS-1) use?

The FREEDOM variant (LCS-1) employs a combination of diesel engines and gas turbines, which allows it to operate efficiently at various speeds and optimize fuel consumption. This propulsion system is known as Combined Diesel and Gas (CODAG). By integrating both types of propulsion, the FREEDOM variant benefits from the fuel efficiency of diesel engines for cruising at lower speeds, while utilizing gas turbines for high-speed maneuvers or when a quick surge of power is needed. This hybrid approach provides flexibility in operations, making the vessel adaptable to a range of mission profiles and requirements.

Using a single diesel engine or electric propulsion would not provide the same versatility and speed benefits as the CODAG system. The traditional propeller mechanism enhances the vessel’s efficiency and maneuverability, aligning with the operational goals of the Freedom variant within the Littoral Combat Ship program.
