RAAArty....whilst I am sitting on the sideline watching progress, however having technical training and experience in gun and director 'fire control systems' I can confirm
On a warship at sea, when the FCS director dome locks onto a target, the director body physically moves .......if we can imagine the director dome is locked onto the target, the dome does not move....it is locked
So when the vessel pitches or rolls, the directors electro hydraulic system is compensating for the movement of the vessel
In slow motion, the director is sending a continuously varying set of co-ordinates to the gun mount fire control system to compensate for the pitch & roll of the vessel
Gun mount director fire control systems were in their absolute infancy in design and use on Dreadnaught vessels.....the scholars suggest approximately only 3% of Capital ordinance firings controlled by director systems in the Battle of Jutland accurately found their mark
On modern day vessels [5000 tonnes] in a war training exercise, the barrel of a 125 mm quick fire gun mount can be visually seen to appear 'hunting in both train and elevation'. This naturally is that the dome of the director and the barrel of the mount are absolutely locked on the target despite the vessels pitch & roll
I doubt if any similar visual scenario would have been evident with the slower movement of 12" or 14" guns on Dreadnaught vessels of 25000 tonnes
