The 2-shaft vertical triple expansion engines and 8 cylindrical boilers supplied 17,000 ihp allowing a speed of 24 knots while she had a coal bunker capacity of 350-1,000 tons. Her crew numbered 350 men. The armament consisted of 2x1-8” (1 fore, 1 aft) guns, 4x1-6” guns, 6x1-4.7” guns, 16x1-3pdr guns and 5x1-18” surfaced torpedo tubes.
