Orion Class Battleship (1910)
Fire Control Systems
Rangefinders
Directors
Main Battery
The ships were fitted with a cam-type tripod-type director in a light aloft tower on the foremast along with a directing gun (in 'X' turret?)[1].
This class was the first in which the main battery could be divided into forward ('A', 'B' & 'Q') and aft ('X' & 'Y') groups for split director control[2].
In all likelihood, a C.O.S. in the TS afforded these options:
- all turrets on aloft tower
- all turrets on directing gun
- forward group on aloft tower, aft group on directing gun
Secondary Battery
The 4-in guns never had directors installed[3].
Torpedo Control
Transmitting Stations
Like nearly all large British ships of the era prior to King George V and Queen Mary[4], these ships likely had 2 TSs.
Dreyer Table
Orion and Conqueror were eventually retro-fitted with a Mark II Dreyer tables, while Monarch and Thunderer received Mark III Dreyer tables[5]. As of June 1918, they had not been provided Dreyer Turret Control Tables[6].
