These ships had no fire control tables.[4]
Fire Control Instruments
By 1909, both in this class were outfitted with the latest Vickers F.T.P. Fire Control Instruments (Mark I in Boadicea, Mark II in Bellona), marking a new wrinkle in equipment by replacing the Barr and Stroud equipment that had taken hold shortly after 1906. The equipment was fitted as follows:[6][7]
- Range Transmitters: 3
- Deflection Transmitters: 3
- Range Receivers: 6
- Deflection Receivers: 6
- C.O.S.: 1
- Vickers Fire Gongs: 6 with 3 keys
None of the ships had Target Visible or Gun Ready signals.[8]
