The Zhongbin-class battleships (: 中滨级战列舰; Zhōngbīn jí zhànlièjiàn) were a pair of pre-dreadnought battleships built for the Imperial Kodeshi Navy (IKN) during the 1900s. ​Her sister ship was the Yu'an which saw action against Beifang during 1907 Kodeshi-Beifang War.

Background
Kodeshia embarked on a program to modernize and expand its fleet. As with the earlier ironclad battleships, Kodeshia lacked the technology and capability to construct its own battleships, and turned again to the Teutonic Empire. They were ordered as part of the Ten Year Naval Expansion Programme by Emperor Qianlong in 1898, under the condition that they be completed within 20 years. This target proved impossible to meet due to the Great Kodeshi Famine and other factors. The construction process itself took longer than expected, however, so it wasn't until 1902 when the ships finally left dry dock.

Design
The design of the Zhongbin-class was based around an improved version of the battleships in Teutonic service. This design incorporated some improvements over previous designs such as larger ballast tanks, more powerful engine mounts, and new machinery including a quadruplex propeller system. Zhongbin-class's most obvious design feature was her tumblehome hull. This had several advantages because it allowed greater freeboard since the narrow upper decks reduced the structural weight of the vessel's hull, it increased the field of fire of guns mounted on the sides, and it reduced the ship's roll in heavy seas. Its great disadvantage was that it reduced buoyancy and stability which contributed to excessive heel during turns. As well as this, there were also many changes made to improve survivability of these vessels. These included small "gull" batteries along their side edges, large number of machine gun ports placed above each main battery turret, additional armour plating between armoured deck plates, and even a few extra watertight compartments added into the bow section of the ship. The Zhongbin-class remained largely unchanged from the original model designed by Teutonic architect Ernst von Bülow, although she received minor modifications throughout the course of construction. The Zhongbin-class ships had an overall length of 110 m (360 ft 10 in), beam of 23.5 m (77 ft 1 in), draught of 16.9 m (55 ft 5 in). They displaced 8,500 tons standard load and 9,000 tons normal load. The crew numbered 1,148 with around 30-48 officers and the rest enlisted sailors.

Propulsion
The ships were powered by two basic steam compound engines, each driving one propeller, using steam generated by 20 natural draft boilers. The engines were rated at 4,367 indicated horsepower (3,256 kW), and designed to reach a top speed of 16.5 knots (30.6 km/h; 19 mph). This allowed for a range of 4,500 nmi (8,300 km; 5,200 mi) at 10 knots (19 km/h; 12 mph).

Armament
The ships carried a main battery of two twin 279 mm (11 in) guns. They were mounted in twin-gun barbettes fore and aft of the superstructure. Secondary armament of the Zhongbin-class consisted of two single 178 mm (6 in) guns four single 127 mm (6 in) guns, fourteen single 76 mm (3 in) guns, two single 51 mm (2 in) guns and four 381 mm (15 in) underwater torpedo tubes, two of these were in the bow and stern, and the two broadside underwater tubes were located amidship.

Armour
The armour scheme of the Zhongbin-class ships was similar to that used by the Teutonic ship except that the Kodeshi ships used superior Harvey armour of the same thickness instead of compound armour. The armoured waterline belt ranged from 115-265 mm (4.5–10.8 in). The deck armour was 35-70 mm (1.3–2.7 in) thick, and the main gun turrets had a thickness of 280 mm (11 in) The conning tower design was protected by a layer of 275 mm (10.8 in) thick armour.

Service
The Zhongbin-class was commissioned in June 12 1895 arriving in Kodeshia from Teutonia and was soon joined by her sister ship the Yu'an in October 5 1896. After being refitted with new machinery and equipment, they departed on February 17 1897 and arrived in Chenghai naval base on May 3 1898. Zhongbin served as the Imperial Kodeshi Navies flagship under Admiral Zheng He's command. They performed various duties such as escort duty and anti-piracy operations against pirates off the coast of Kodeshia.

Kodeshi-Beifang War
At the start of the Kodeshi-Beifang War in 1907, Zhongbin and Yu'an were assigned to the 1st Division of the 1st Fleet. They participated in the Battle of Zhoushan Bay where they were attacked by the Beifang fleet led by Vice Admiral X. During this engagement, both ships suffered heavy damage including loss of their forward magazines which caused severe flooding. Yu'an would have to be scuttled due to reduced buoyancy of the tumblehome hull. In addition, she lost over half her crew during the battle. However, despite losing more than 50% of her complement, she still managed to complete the mission successfully.

Grand Campaigns
By the time of the outbreak of the Grand Campaigns Zhongbin was reclassified as a coastal defence ship. Her role changed considerably when she became part of an coastal force commanded by Vice Admiral Zhang Qian. Under his leadership, she launched several shore bombardment attacks along the Taiyi River at Selengerian forces who were trying to invade Kodehsia. This allowed him to capture many fortifications while also inflicting considerable casualties upon the enemy. His actions earned Zhongbin some fame amongst the public. Zhongbin would take part in the later stages of the Tang Offensive of 1924 as part of a naval force conducting shore bombardment and escorting the battleship Tianlin and the navies first aircraft carrier.

Kodeshian Civil War
As a coastal defence ship Zhongbin remained loyal to the Emperor once the civil war broke out in 1927. She acted as one of two main warships protecting the capital city of Songhari during the rebellion that erupted there between royalist and republican factions. Eventually the ship was surrendered to the new Kodeshi State once the royalist forces were defeated.

Poja Service
Zhongbin and number of other vessels underwent an extensive refit and were sold to the Confederacy of Poja in the 1920s. The ship would be decommissioned and transferred to the Pojacki Navy. Zhongbin was renamed something; she thereafter became part of the Pojacki fleet. By the 1930, something was placed in inactive reserve; sections of her armour plate was removed to build fortifications. She was disarmed and thereafter used as a barracks ship for cadets from the Naval Academy. Eventually she sold for scrap in the 1940s.
