The Redbreast class comprised nine first-class screw-driven composite gunboats built for the Royal Navy in 1889, mounting 6 guns.

Construction

Design

The Redbreast class were designed by Sir William Henry White, the Royal Navy Director of Naval Construction in 1888.[1] The hull was of composite construction, that is, iron keel, frames, stem and stern posts with wooden planking. These were the last class of composite-hulled gunboats built for the Royal Navy - the next class of gunboat, the Bramble-class gunboat of 1898, was of steel construction.

Propulsion

The class was fitted with a triple-expansion reciprocating steam engine developing 1,200 indicated horsepower, sufficient to propel them at 13 kn (24 km/h) through a single screw.

Sail plan

The class was given a barquentine rig.

Armament

The first four ships were armed with six 4-inch/25-pounder (25cwt) quick firing guns and four machine guns. The last five had an additional pair of 3-pounder quick firing guns in place of two of the machine guns.[1]
