What is the PLCC called on new 51 class ships?

The correct term for the PLCC on new 51 class ships is the Shaft Control Unit. This component plays a critical role in managing the dynamics of propulsion, specifically focusing on the performance and control of the ship's shafts. The Shaft Control Unit is responsible for ensuring that the power generated by the gas turbines is efficiently transmitted to the propellers, allowing for optimal maneuverability and speed.

This unit integrates various systems that monitor and control shaft speed, direction, and positioning. By accurately regulating these parameters, the Shaft Control Unit helps maintain the vessel's stability and performance during operations.

In terms of related options, the Power Load Control Center is more associated with broader electrical load management systems rather than specifically controlling the propulsion shafts. The Pump Control Console typically pertains to managing fluid pump operations, and the System Control Unit does not specifically designate the focus on shaft control. Hence, the designation of Shaft Control Unit emphasizes its specific functionality and relevance to the operation of new 51 class ships.
