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.
The Alfonso XII class had three masts and two funnels. They were unarmored, but their hulls were built with a French-style cellular system with 12 watertight bulkheads. The Ferrol-built ships were the first two steel-hulled cruisers built in that yard. The main guns were built by Hontoria and mounted in sponsons. The torpedo tubes were fixed; one was on each beam, two were forward, and one was aft. The class took a long time to complete; the lead unit was delayed for five years by material shortages and took ten years from keel-laying to commissioning.
The ships were designed for colonial service, and were not intended to fight the armored and heavily armed ships they would meet in the Spanish–American War. They were plagued by machinery and boiler problems, and proved to be much slower steamers than their designers had intended.
After early service in home waters, the Alfonso XII-class cruisers were assigned to colonial duty in the Caribbean and Philippines. Thanks to machinery and boiler problems, only one was seaworthy during the Spanish–American War, and two were lost during the conflict, one of the sunken ships being salvaged and put into service in the United States Navy. The lone survivor in Spanish service was decommissioned soon after the war.
Named for a Spanish king and laid down in 1881, Alfonso XII was delayed during construction for five years by material shortages and not completed until 1891. She was immobilized at Havana, Cuba, by machinery and boiler trouble by 1897, and was anchored only 200 yards (180 m) from the battleship USS Maine when the latter exploded in February 1898. Unable to get underway, she took no part in the ensuing Spanish–American War except to land her guns for use in coastal defenses. She was decommissioned in 1900, the last survivor of the class in Spanish service.
