Arrow-class gunvessel

The Arrow class comprised six second-class screw-driven vessels built as dispatch vessels for the Royal Navy in 1854, mounting six guns. In 1856 they were re-designated as second-class gunvessels. A seventh vessel was built for the Argentine Navy in 1875.

Design
The Crimean War sparked a sudden need for shallow-draught, manoeuvrable vessels for inshore work in the Baltic and the Black Sea. The Arrow class of six wooden-hulled screw steamers were built during 1854 to a design by the Surveyor's Department. Construction was undertaken at two commercial yards on the Thames, R & H Green at Blackwall Yard and C J Mare & Company, at Leamouth. Two further designs of Crimean War gunvessel were ordered during 1855, the Intrepid-class gunvessel and the Vigilant-class gunvessel, and in 1856 the six Arrow-class dispatch vessels were re-classed as second-class gunvessels.

Propulsion
A two-cylinder horizontal single expansion steam engine provided 160 hp through a single screw.

Sail plan
All Arrow-class gunvessels were barque-rigged.

Armament
The Arrow class were provided with two 68-pounder Lancaster muzzle-loading rifles weighing 95 long cwt on pivot mounts, and four 32-pounder 25 long cwt guns.

Operational lives
Wrangler was sent to the Baltic on completion, and the others of the class to the Black Sea where they took part in the Crimean War. The Lancaster guns were not entirely successful, and the class had their armament reduced, being employed in their original designation as dispatch vessels.
