What centralized fire control meant aboard Sydney

What centralized fire control did HMAS Sydney have?

A director and central gunnery position coordinated firing data, though it was less integrated than later rangefinder-based systems.

HMAS Sydney's arrangement used a director and a central gunnery officer to coordinate the ship's fire. The central position could average the information available and transmit firing orders to the guns. That made it a genuine form of centralized control by the standards of the time. It was not yet the tightly integrated rangefinder and computing system suggested by later fire-control terminology.
