Protected cruisers were a type of naval cruiser of the late 19th century. They were so known because they had only a minimal amount of armor compared to existing "armored" cruisers. In around 1910, when armor plate began to increase in quality and engines became lighter, they were superseded by light and heavy cruisers.
Most of their armor was used on the special deck inside the vessel, protecting boilers and steam machines, trapezoid-like in cross-section. Also guns and conning tower could be armored.
The armor tended to range from 2 to 3 inches (5 to 7.5 cm) in thickness.
The displacement of protected cruisers was about 2500 - 7000 tons. Main armament was up to a dozen single guns between 3.9 and 6 inches (100mm - 152mm). Speed was usually about 18 - 23 knots.
Protected cruisers appeared about 1880 and disappeared about 1910, when countries started to build light cruisers, with armored sides and decks instead.
