The two armoured cruisers of the Duke of Edinburgh Class were completed in 1906.

Fire Control

Rangefinders

Evershed Bearing Indicators

It is unlikely that this equipment was ever provided.[Inference]

Directors

In 1916, it was approved that the ships of this class should be retrofitted with directors as time, resources and opportunity permitted,[1] but these plans were slow to execute. Duke of Edinburgh received one in October 1918, but Black Prince was likely lost before her equipment was ever ordered.[2][Inference]

Gunnery Control

Local Control in Turrets

Transmitting Stations

Dreyer Table

These ships never received Dreyer tables.[3]

Fire Control Instruments

By 1909, both ships were equipped with Vickers, Son and Maxim instruments for range, deflection and orders and with Barr and Stroud rate instruments as follows:[4]

  • Vickers range transmitters: 10
  • Vickers deflection transmitters: 10
  • Vickers combined range and deflection receivers: 33
  • Vickers C.O.S.: 5
  • Vickers Check fire switches: 10
  • Barr and Stroud rate transmitters: 4
  • Barr and Stroud rate receivers: 8
  • Siemens turret fire gongs: 12 with 6 keys
  • Vickers fire gongs: 10 with 4 keys
  • Captain's Cease Fire Bells: 16 (16 in Duke of Edinburgh) with 1 key (supplier not stated)

As in the Minotaur class, bearing instruments were installed in or by 1915. The receivers in the four 9.2-in broadside guns and the 6-in officers' positions are operated in by transmitters in the TS for their side or by their respective master transmitters in the foretop. The two centre-line turrets are connected to a transmitter in the TS or to one of the master transmitters. The 6-in guns are worked om transmitters in the O.O.Q. position on that side.[5] The overall bill of fare ran to:

  • 2 special "master" bearing transmitters, Graham's type (in foretop, P&S)
  • 6 Barr and Stroud bearing transmitters:
    • 2 in the O.O.Q.'s position, P & S
    • 2 in the foretop, P & S
    • 2 in the TS, P & S
  • 23 Barr and Stroud bearing receivers:
    • 10 for the 6-in guns (1 each)
    • 6 for the 9.2-in guns (1 per turret)
    • 2 in the O.O.Q.'s position, P & S
    • 1 repeat in the fore TS
    • 2 repeats in the foretop
  • Three C.O.S. (one in fore TS, and two in foretop)

These ships lacked Target Visible and Gun Ready signals.[6]
