Main Battery
These ships were fitted with 2 cam-type tripod-mounted directors, one in an armoured tower and one in a light aloft tower[1]. There were no directing guns[2].
The guns could be divided into a forward ('A' & 'B') and aft ('Y') groups. Inferring from other ships with 2 directors[3], a C.O.S in the T.S. permitted these control options:
- All guns on aloft director
- All guns on armoured director
- Forward group on aloft director, aft group on armoured director
It is likely that each gun had a local C.O.S. with 3 positions[Inference]:
- Gunlayer's Firing (aux and main circuits connected to local triggers)
- Director 1 (local main to director main, local aux to director aux)
- Director 2 (local main to director aux, local aux to director main)
Secondary Battery
The 4-in guns were supported by a pair of pedestal-mounted directors with double cam grooves and two rollers, one forward (on foremast below the spotting top) and one aft (on mainmast)[4]. This placement helped support that subset of the guns capable of firing to either side.
