the problems which the Navy granted since the construction of the ship was already behind schedule. On her final set of sea trials in November 1895, Navarin reached a top speed of . She carried a maximum of of coal that provided a range of at a speed of . Armament The ship's main battery consisted of four 35-caliber Obukhov Model 1886 guns mounted in hydraulically powered twin-gun turrets fore and aft of the superstructure. The guns required 2 minutes, 22 seconds between shots. They fired a "light" shell at a muzzle velocity of . Each gun was provided with 80 rounds. Her secondary armament of eight 35-caliber Pattern 1877 guns were mounted in casemates in the superstructure. The ship carried a total of 1,600 rounds for them. Navarin was protected against torpedo boats by a suite of smaller guns that included fourteen quick-firing (QF) Hotchkiss guns mounted in the superstructure. They fired a shell at a muzzle velocity of . A total of eight Maxim QF guns were mounted in the fighting top and the other four guns may have been used to arm the ship's boats. They fired a shell at a muzzle velocity of . Navarin was also armed with six above-water torpedo tubes, one each in the bow and stern and one pair on each broadside. The ship carried two torpedoes for each tube. Protection The ship used compound armor for all armored vertical surfaces except for the gun turrets which were made from nickel steel. The maximum thickness of the waterline armor belt was which reduced to abreast the magazines. It covered of the ship's length and was high, and tapered down to a thickness of at the bottom edge. The upper of the belt was intended to be above the waterline, but the ship was significantly overweight and much of the belt was submerged. The belt terminated in transverse bulkheads. The lower casemate was above the belt, long and high, and was intended to protect the bases of the turrets and everything between them. It had 16-inch sides and was closed off by 16-inch transverse bulkheads fore and aft. The upper casemate protected the six-inch guns and was thick on all sides. The armor plates of the turret sides were 16 inches thick and the conning tower had sides that were thick. The armor deck was thick over the lower casemate, but thick forward
