The 4 third class cruisers of the Gem Class were completed in 1904 and 1905.
Fire Control
Rangefinders
Evershed Bearing Indicators
This equipment was unlikely to have been fitted for gun or searchlight control.[1] [Fact Check]
Gunnery Control
The ships were hard-wired for Telaupad control. Five Navyphones and fire gongs on flexible cables were to be placed in any convenient position for controlling the armament in whole or in part. Six group officer's navyphones were (also?) provided. The flying bridge housed 4 C.O.S.

Four groupings were possible for the forward guns:
- The three foremost broadside guns in 2 groups, port and starboard, with forecastle gun as third group.
- Number 2 and 3 broadside gun in two groups, port and starboard, with Number 1 broadside gun and fore gun as third group.
- As 1, but with forecastle gun in port group
- As 1, but with forecastle gun in starboard group
The aft guns had simpler groupings:
- broadside guns 4 and 5 in 2 groups, port and starboard, quarterdeck gun with port group.
- Same as above, but quarterdeck gun with starboard group.
