Searchlights

In 1907, these ships, along with the later Drake, Cressy, Monmouth and Devonshire classes and battleships of the Majestic, Canopus, London, and Duncan classes, were to land their searchlights from their tops and obtain two additional 24-inch models from their dockyards for placement on the shelter or boat deck.[1]

Armament

Main Battery

9.2-in Electricals[2]

The 9.2-in gun turrets were trained and their ammunition hoisted by electric motors.[3]

Secondary Battery

Torpedoes

The aft submerged torpedo tubes were angled 45 degrees abaft the beam.[4]

Fire Control

Rangefinders

Evershed Bearing Indicators

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

Directors

These ships never received directors for main or secondary batteries.[5]

Gunnery Control

Local Control in Turrets

Transmitting Stations

Dreyer Table

These ships never received Dreyer tables.[6]

Fire Control Instruments

By 1909, both ships were equipped with Siemens Mark I Fire Control Instruments for range, orders and deflection.[7]

The Handbook for Fire Control Instruments, 1909 lists the Mark I equipment for as:[8]

  • Range: 6 transmitters, 34 receivers
  • Orders: 6 transmitters, 24 receivers in Powerful and 20 in Terrible
  • Rate: 4 transmitters, 12 receivers
  • Deflection: 6 transmitters, 34 receivers

Additionally, the entire class had the following Siemens equipment:[9]

  • Group Switches: 3
  • Turret fire gongs: 2 with 1 keys
  • Fire Gongs: 20 in Powerful, 16 in Terrible, both with 4 keys
  • Captain's Cease Fire Bells: 20 with 1 key
