These vessels were the first fleet scouts. They are of about 3,000 tons displacement, and have engines of 16,500 h.p., which give them a speed of 25 knots. As originally armed, they carried a battery of 12-pounders, but these were replaced recently by nine 4-in. quick-firers, a change which much increased the fighting value. The coal supply is 400 tons, and they have a complement of 268 officers and men. The average cost, complete, was over £270,000.
