Fire Control Instruments
By 1909, the 6 ships in this class were equipped with Vickers, Son and Maxim instruments for range, deflection and orders and with Barr and Stroud rate instruments:[2]
- Vickers range transmitters: 6
- Vickers deflection transmitters: 6
- Vickers combined range and deflection receivers: 23
- Vickers C.O.S.: 3
- Vickers Check fire switches: 6
- Barr and Stroud rate transmitters: 4
- Barr and Stroud rate receivers: 8
- Siemens Fire Gongs (turrets): 4 with 2 keys
- Vickers Fire Gongs (elsewhere): 12 with 4 keys
- Siemens Captain's Cease Fire Bells: 18 with 1 key
These ships lacked Target Visible and Gun Ready signals.[3]
Radio
In 1901, Cressy with the China Squadron and Aboukir in Reserve were listed as having or slated to receive a "1 to 52" W/T set.[4] Based on the push to deploy wireless in such units, it is likely that her sisters were completed with W/T or received them shortly thereafter.[Inference]
