. The ship had a partial double bottom and a centreline bulkhead separated the engine and boiler rooms. Sissoi Velikys crew initially consisted of 27 officers and 555 enlisted men, but grew to a total of 686 by 1905. Sissoi Veliky had two vertical triple-expansion steam engines, each driving one four-bladed propeller. They had a total designed output of using steam provided by 12 cylindrical fire-tube boilers. The ship's designed speed was , but she reached a top speed of during her sea trials on 1896, despite from her engines. She carried a maximum of of coal at full load that gave her a range of at a speed of . Armament Like many Russian ships before and after it, Sissoi Veliky was plagued by regular "improvements" of the original design that delayed construction for years. In the beginning of 1893, over a year after construction began, the MTK again redesigned Sissoi Velikys artillery. The two pairs of 12-inch 40-calibre guns were changed from barbette mountings to French-style twin turrets. These guns had a maximum elevation of +15° and the ship carried 80 rounds per gun for them. Their rate of fire was intended to be one round per 1.5 minutes, but it was one shot per 2.5–3 minutes in reality. They fired a shell at a muzzle velocity of to a range of at an elevation of +10°. The secondary armament was replaced by a half-dozen 45-calibre quick-firing (QF) six-inch (152 mm) Canet guns that were mounted in casemates on the main deck. Each gun was provided with 200 rounds of ammunition. Alterations of the shell hoists to accommodate the larger rounds for the Canet guns began only in December 1895. They fired shells that weighed with a muzzle velocity of . They had a maximum range of when fired at an elevation of +20°. The ship's anti-torpedo boat armament was changed more than once and, in the end, consisted of a dozen QF Hotchkiss guns and 10 Maxim QF guns. The 47 mm guns were mounted on the top of the superstructure and on the upper deck above the six-inch casemates. They fired a shell at a muzzle velocity of . The 37 mm guns were mounted in the fighting top. They fired a shell at a muzzle velocity of . Sissoi Veliky carried six above-water torpedo tubes, one each in the bow and stern and two on
