Fire Control Systems

Rangefinders

Directors and Gun Groups

Main Battery

These ships were fitted with 2 tripod-type directors, one in an armoured tower and one in a light aloft tower[1] as well as a directing gun[2].

The main battery was divisible into two groups, fore (A & B) and aft (X & Y)[3].

A C.O.S. in the T.S offered the following options[4]:

  1. all guns on aloft director
  2. all on armoured director
  3. all on directing gun
  4. forward group on aloft director, aft group on armoured director
  5. forward group on armoured director, aft group on directing gun

Each gun had a local C.O.S. with 3 positions:

  1. Gunlayer's firing (local trigger circuits connected)
  2. Director 1 (director main to local main, director aux to local aux)
  3. Director 2 (director main to local aux, director aux to local main)

Secondary Battery

All units except Queen Elizabeth had pedestal-mounted directors for their secondary batteries. Queen Elizabeth's 6-in guns were supported by a pair of tripod-mounted directors [5].

The secondary directors were situated port and starboard high on her forward superstructure[6].

The broadside-mounted secondary guns were in port and starboard groups, and either were laid and fired locally or under the control of the director on their side.

Torpedo Control

Transmitting Stations

Dreyer Table

All ships had Mark IV* tables, although it is possible that Queen Elizabeth was originally given a Mark IV Dreyer table which was later upgraded to the Mark IV* standard[7].

Each ship also had 4 (?) Dreyer Turret Control Tables[8].
