Originally laid down for a casemated monitor, but subsequently transformed into an armored-belt corvette. Straight bow and stern, the bow being heavily strengthened for ramming,single screw, full sail-power (double topsail-yards). The belt encloses the water-line to the height of the upper deck. The battery is all on the upper deck and entirely unprotected. The upper-deck rail is so fashioned as to give four guns for bow and four for stern fire. Forward it is recessed on each bow, and similarly astern for the forward and after guns to get bow and beam fire. (See Amethyst, English.) The platform for the next pair of guns (forward and aft) has an overhang of about three feet (see Tourville, French), in order to give them clear fore-and-aft and beam fire also. The remainder of the battery is broadside. Her spar-deck rail is very high (about eight feet); she has a topgallant forecastle and poop-cabin. Amidships there is a bridge for discharging Whitehead torpedoes. PETER THE GREAT. Armored, belt, breastwork, and double-turreted sea-going monitor, straight bow strengthened for ramming, double screws, no sail-power. Musket-proof superstructure between the turrets expanding into a flying deck. The belt has an overhang similar to the American monitors. General type similar to the Dreadnaught. [Illustration: PETER THE GREAT.] ADMIRAL POPOFF. NOVGOROD. [Illustration] Armored belt and barbette casemate, circular iron-clads. Six screws, no sail-power. The belt of these ships encloses the water-line to the height of the low freeboard. The deck has more than the ordinary spring, forming a sort of light glacis. In the centre of the vessel rises a circular barbette casemate, covering the carriages of two heavy guns mounted on a turn-table within it. Forward and aft the top of the casemate is continued in a musket-proof superstructure, having aft a musket-proof pilot-house. The forward section of the vessel is heavily strengthened for ramming. The two smoke-stacks are placed one either side of the casemate. [Illustration: _Stern View_] [Illustration] DOUBLE AND SINGLE TURRETED MONITORS. These vessels are of the general type of the American monitors, with slight freeboard, great overhang, and double screws. The turret is raised somewhat higher than in the American monitors, and the foot is protected by a glacis. The turret is also somewhat larger, giving clear fire past the smoke-stacks. Pilot-house on top of the turret. [Illustration: URAGAN.] RUSSIAN GENERAL-SERVICE FLEET.
