This US Navy training film covers the integrated fire control system for a warship's main battery — the chain from initial target detection through firing solution. It explains how surface search radar and optical rangefinders feed target data into the fire control director, how the ship's motion and target motion are continuously tracked, and how the analog fire control computer translates that data into gun elevation and train orders delivered to the gun mounts.
The film documents main battery fire control at the moment when radar-directed gunnery had matured but digital fire control had not yet arrived — the apex of the mechanical analog fire control era.
