What is the PLCC called on a guided missile frigate (FFG)?

The correct answer, Control Logic Center, is significant as it refers specifically to the system utilized within a guided missile frigate that plays a crucial role in managing various functions of the ship's systems. The Control Logic Center serves as the central hub for processing signals and commands related to ship operations, particularly those that involve weapons systems, navigation, and environmental control.

In the context of guided missile frigates, the PLCC is essential for ensuring that the different mechanical systems work in concert, allowing for efficient operation and response during missions. It integrates data from various sensors and mediates communication across different platforms aboard the ship, which is vital for maintaining effective situational awareness and control during naval operations.

The other options, while they might seem plausible, do not accurately reflect the terminology used for this particular system on frigates. The Local Operations Panel and Local Operations Control, for example, imply a more localized control aspect that is not comprehensive enough to encompass the broader range of functions and authority that the Control Logic Center embodies. Line Operations Control may suggest operational management but does not convey the specific technical structure and functioning as represented by the Control Logic Center.
