An ironclad was a steam-propelled warship protected by steel or iron armor constructed from 1859 to the early 1890s. The ironclad was developed as a result of the vulnerability of wooden warships to explosive or incendiary shells. The first ironclad battleship, Gloire, was launched by the French Navy in November 1859, narrowly preempting the British Royal Navy. However, Britain built the first completely iron-hulled warships.
Pre-dreadnought battleships were sea-going battleships built from the mid- to late- 1880s to the early 1900s. Their designs were conceived before the appearance of HMS Dreadnought in 1906 and their classification as "pre-dreadnought" is retrospectively applied. In their day, they were simply known as "battleships" or else more rank-specific terms such as "first-class battleship" and so forth. The pre-dreadnought battleships were the pre-eminent warships of their time and replaced the ironclad battleships of the 1870s and 1880s.
Takao (高雄) was an unprotected cruiser of the Imperial Japanese Navy. The name Takao comes from the Mount Takao, near Kyoto. Takao was used by the Imperial Japanese Navy primarily as an aviso or dispatch boat, for scouting, reconnaissance and the conveying of important messages.
Reina Cristina was an Alfonso XII-class unprotected cruiser of the Spanish Navy built at the naval shipyard at Ferrol and launched 2 May 1887. Reina Cristina spent her early years in Spanish waters. In 1894 she was transferred to the Spanish Navy's Asiatic Squadron to deter any aggressive moves the German Empire might take against the Spanish-owned Caroline Islands in the Pacific. When Spain faced the "Tagalog Revolt" (1896–1897) – the Spanish name for the first two years of the Philippine Revolution – in the Philippine Islands, Reina Cristina was actively involved in the Spanish campaign to put down the revolt. In addition to patrolling Philippine waters to prevent the smuggling of contraband to the insurgents, she also supported Spanish Army actions against them at Cavite, Novaleta, and Binacayan, including the provision of naval gunfire support to Spanish troops ashore.

Don Juan de Austria was a Velasco-class unprotected cruiser of the Spanish Navy that fought in the Battle of Manila Bay during the Spanish–American War.
Castilla was an Aragon-class unprotected cruiser of the Spanish Navy that fought in the Battle of Manila Bay during the Spanish–American War. She was built at Cadiz, Spain. Her construction as an armored corvette with a central battery ironclad design began in 1869. In 1870, her design was changed to that of an unprotected cruiser or wooden corvette, and, after political events delayed her construction. During the first two years of the Philippine Revolution in 1896–1897, Castilla patrolled to intercept contraband destined for the Philippine insurgents and supported Spanish Army forces fighting ashore in Cavite Province on Luzon. When the Spanish–American War broke out in April 1898, Castilla was part of the squadron of Rear Admiral Patricio Montojo y Pasarón in Manila Bay and was subsequently engaged and sunk in the Battle of Manila Bay.
Emperador Carlos V was an armored cruiser of the Spanish Navy which served in the Spanish fleet from 1898 to 1933. The money intended to build torpedo boats was used to build a 9,000-ton cruiser, deriving this cruiser from the British Blake class. Said cruiser stood out for its great autonomy, while it suffered from having little armor, mounting only during its first days of life 4 pieces of García Lomas of 100 mm.
The Infanta Maria Teresa class of three armored cruisers were built for the Spanish Navy between 1889 and 1893. All three were sunk in action against the United States Navy during the Battle of Santiago de Cuba in 1898.
The Alfonso XII class of unprotected cruisers was a series of three ships built during the 1880s for service with the Spanish Navy. They were named for a Spanish king and two Spanish queens.

Andrea Doria was an ironclad battleship built for the Italian Regia Marina in the 1880s and 1890s. Named for the 16th-century Genoese admiral Andrea Doria, she was the third and final ship of the Ruggiero di Lauria class. The ship was armed with a main battery of four 432 mm (17 in) guns, was protected with 451 mm (17.75 in) thick belt armor, and was capable of a top speed of 17 knots.
SMS Gefion was an unprotected cruiser of the German Kaiserliche Marine, the last ship of the type built in Germany. She was laid down in March 1892, launched in March 1893, and completed in June 1895 after lengthy trials and repairs. The cruiser was named after the earlier sail frigate Gefion, which had been named for the goddess Gefjon of Norse mythology. Intended for service in the German colonial empire and as a fleet scout, Gefion was armed with a main battery of ten 10.5-centimeter (4.1 in) guns, had a top speed in excess of 19.5 knots, and could steam for 3,500 nautical miles, the longest range of any German warship at the time. Nevertheless, the conflicting requirements necessary for a fleet scout and an overseas cruiser produced an unsuccessful design, and Gefion was rapidly replaced in both roles by the newer Gazelle class of light cruisers.
Miyako (宮古) was an unprotected cruiser of the early Imperial Japanese Navy. The name Miyako comes from the Miyako Islands, one of the three island groups making up current Okinawa prefecture. Miyako was used by the Imperial Japanese Navy primarily as an aviso for scouting, reconnaissance and delivery of high priority messages.
An unprotected cruiser was a type of naval warship that was in use during the early 1870s Victorian or pre-dreadnought era. The name was meant to distinguish these ships from “protected cruisers”, which had become accepted in the 1880s. A protected cruiser did not have side armor on its hull like a battleship or “armored cruiser” but had only a curved armored deck built inside the ship — like an internal turtle shell — which prevented enemy fire penetrating through the ship down into the most critical areas such as machinery, boilers, and ammunition storage. An unprotected cruiser lacked even this level of internal protection. The definitions had some gray areas, because individual ships could be built with a protective deck that did not cover more than a small area of the ship, or was so thin as to be of little value. The same was true of the side armor on some armored cruisers. An unprotected cruiser was generally cheaper and less effective than a protected cruiser, while a protected cruiser was generally cheaper and less effective than an armored cruiser, with some exceptions in each case.
Dubordieu was an unprotected cruiser built for the French Navy in the early 1880s. Intended to serve as a long-range commerce raider, the ship was fitted with a sailing rig to supplement its steam engine on long voyages, and she carried an armament of four 165 mm (6.5 in) and twelve 140 mm (5.5 in) guns. She was among the final French unprotected cruisers, thereafter being replaced by more durable protected cruisers. The French Navy was not satisfied with the vessel, owing to her obsolescent design, since she too weak to defeat the more powerful protected cruisers and was too slow to escape from them.
