The British reported extensively on the details of this class in their 1903 Annual Report of the Torpedo School.[1]

This class increased the voltage previously used to 125 volts.[2]

Two distinct electrical systems were installed, "battle service" and "lighting service", with separate mains and feeders. Battle service supplied everything required in action: all lights below the protective deck (engine room, magazines, lighting at guns hoists, winches). Lighting service was for comfort items, such as in cabins, messes, and the forty five 12-in desk fans and eight 16-in fans in the officers' quarters. There were 1,100 lighting fixtures in all, 730 of them on the battle service.[3]


Six 30-in hand-controlled projectors. They ran on 125 volts, drawing 80 amperes with 60 volts across the arc.[4]


Main Battery

The two 12-in and four 8-in turrets trained electrically, each driven by two identical motors (25/15 H.P. for the 12-in and 8-in turrets, respectively). The training motors ordinarily worked together, but either was capable of training the turret individually.[5] The Ward-Leonard control systems were modified over the system used in the previous class.[6]

The same guns had 7/5 H.P. rammer motors. Each gun had its own ammunition hoist (30/8 H.P.) which would rapidly reverse and could run in any of five speeds. Elevation was also electrical, by 5/2.5 H.P. motors.[7]

Secondary Battery

The 7-in guns were trained and elevated by hand.[8]


The British recorded the particulars in 1911 as[9]

  • four 21-in torpedoes firing on the broadside in two submerged flats

At 5 metres, the torpedoes were noted as being only as long as British 18-in torpedoes.

Twelve torpedoes were allowed, but generally six were in the forward flat and five in the aft.
