Protected Cruiser
Protected cruisers, a type of naval cruiser of the late-19th century, gained their description because an armoured deck offered protection for vital machine-spaces from fragments caused by shells exploding above them. Protected cruisers resembled armored cruisers, which had in addition a belt of armour along the sides. Evolution From the late 1850s, navies began to replace their fleets of wooden ships-of-the-line with armoured ironclad warships. However, the frigates and sloops which performed the missions of scouting, commerce raiding and trade protection remained unarmoured. For several decades, it proved difficult to design a ship which had a meaningful amount of protective armour but at the same time maintained the speed and range required of a "cruising warship". The first attempts to do so, armored cruisers like , proved unsatisfactory, generally lacking enough speed for their cruiser role. During the 1870s the increasing power of armour-piercing shells made ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

These watches are divided into work periods to ensure that the roles are always occupied at all times, while those members of the crew who are assigned to work during a watch are known as ''watchkeepers''.

Typical bridge watchkeepers include a lookout and a deck officer who is responsible for the safe navigation of the ship; whereas in the engine room, an engine officer ensures that running machinery continues to operate within tolerances.
