Directors
Main Battery
The ships were fitted with a tripod-type director in a light aloft tower on the foremast along with a directing gun in the Y turret[1]. The battery was not divisible into for split director firing[2].
Secondary Battery
The 4-in broadside guns are not listed as ever having had directors installed[3].
Torpedo Control
Transmitting Stations
Like all large British ships of the era prior to King George V and Queen Mary, these ships had 2 TSs[4].
Dreyer Table
As of 1917, the surviving units still carried the Mark I Dreyer tables they'd been outfitted with[5]. Indefatigable was lost with her Mark I table[6] at the Battle of Jutland.
The ships were never given Dreyer Turret Control Tables[7].
Shipwide Network
The ships used Vickers F.T.P. Mark III range and deflection instruments to send data to gun sights, retaining Barr and Stroud (probably Mark II*[Inference]) instruments for other destinations[8].
Target Visible and Gun Ready signals mounted in the TSs and control positions indicated which turrets could see the target and which guns were ready[9].
