Director Firing is a means of harmonising and centralising the pointing (and often firing) of a number of guns. It relies upon a director situated high above the deck to place sights on the target and determine the elevation and training for the guns. These angles are then transmitted to the guns where the gunners work to follow the example.
Some precocious and partial examples of director firing, at least in part, extend back into the 19th century. Results were often mixed, or obtained in experiments not enjoying serious support and true consideration of development.[Citation needed]
