Armament

The Ariel-class gunboat was a class of nine 4-gun composite gunboats built for the Royal Navy between 1871 and 1873. Although most were sold by 1890, one of them survived into the 1920s as a salvage vessel in private ownership. They were the first class of Royal Navy gunboat built of composite construction, that is, with iron keel, stem and stern posts, and iron framing, but planked with wood.

Design and construction

Designed by Sir Edward Reed, Chief Constructor of the Royal Navy, the Ariel-class gunboats were the first Royal Navy gunboats of composite construction.[2] They were some of the first vessels to be fitted with compound-expansion engines, allowing the Royal Navy to experiment with new engine designs at little risk in small, cheap vessels.[2][Note 1] These engines were rated 60 nominal horsepower (an indicated horsepower of between 461 ihp (344 kW) and 534 ihp (398 kW)). They were armed with two 6-inch (150 mm) 64-pounder (56cwt) muzzle-loading rifles and two 4-inch (100 mm) 20-pounder Armstrong breech loaders. All 4 guns were mounted on traversing carriages. Some of the class were re-armed in the 1880s with two 5-inch and two 4-inch breech loaders. All the ships of the class carried a three-masted barquentine rig.[1]
