Rangefinders
Directors
Main Battery
The ships were fitted with a tripod-type director in a light aloft tower on the foremast[1] along with a directing gun. The battery was divisible into fore (A & B) and aft (Q & Y) groups, and a C.O.S. in the T.S. allowed the following modes of control[2]:
- all turrets on aloft director
- all turrets on directing gun
- forward group on aloft, aft group on directing gun
By 1917, Lion and Princess Royal were awaiting fitting of a second tripod-type director aft, at which time they would have been fitted with a 5-way C.O.S., possibly in the manner[3]:
- all turrets on forward aloft director
- all turrets on aft director
- all turrets on directing gun
- forward group on forward director, aft group on aft director
- forward group on forward director, aft group on directing gun
Secondary Battery
The 4-in broadside guns are not listed as ever having had directors installed[4].
Torpedo Control
Transmitting Stations
Dreyer Table
At the Battle of Jutland, Lion and Princess Royal carried Mark III Dreyer tables[5], while Queen Mary was using a Mark II Dreyer table when she was destroyed[6][7].
By 1917, Lion and Princess Royal had been upgraded to a Mark IV* Dreyer table, but had no Turret Control Tables[8].
