Imperieuse-class cruiser


The Imperieuse-class cruiser was a class of two armoured cruisers launched between 1883 and 1884 for the Royal Navy.

Description

In an 1886 magazine article, Sir Edward Reed complained that these ships did not deserve to be called "armoured", as they were not armoured at bow or stern, only along the middle of each side. This armour belt was additionally only wide, and as designed would have extended above the waterline. As completed, the two ships were overweight, with the result that the belt was completely submerged, leaving them armoured in name only.
The layout of the main armament was unusual for the time, having one gun each forward and aft, and another gun mounted on either beam – in a lozenge arrangement similar to that employed by the French. The original secondary battery comprised ten 6-inch guns, but the overweight condition of these ships forced the elimination of four of these weapons.
Intended for prolonged deployments on distant foreign stations, the ships were sheathed with wood and copper to prevent marine growth on the hull, and were originally fitted with a brig sailing rig to economize on coal. After trials showed them to be sluggish under sail, the masts and yards were removed and replaced by a single pole mast between the funnels. This reduction in rig and the weight saved thereby allowed the reinstallation of two 6-inch guns, for a total of eight.
