Which control system is implemented on DD-class ships?

The control system implemented on DD-class ships is the EPCE, which stands for Engineering Plant Control Equipment. This system is designed for managing and controlling various aspects of the ship's propulsion and auxiliary systems, ensuring efficient operation and optimal performance.

The EPCE system integrates various functionalities, including monitoring engine performance, controlling fuel flow, and managing power distribution. It serves as a crucial component for the operations of DD-class ships, which are known for their advanced technology and capabilities. By utilizing the EPCE, operators can effectively oversee the ship's machinery, responding quickly to any operational changes or needs.

The other options, such as EPCC, EPCA, and EPCI, refer to different configurations or systems that may be relevant but are not specifically designated for DD-class ships. Each of these may serve similar purposes in other classes of vessels but do not offer the same level of integration or design tailored specifically for the DD-class operational requirements.
