HMS Dwarf (1843) was an iron screw steam yacht, notable for being the first screw-propeller driven warship acquired by the Royal Navy. Originally built as a private vessel, she was purchased by the Admiralty in the same year she was launched, marking a significant early step in the Royal Navy's adoption of screw propulsion technology.
Design and Construction
Built by Ditchburn & Mare at Blackwall, London, Dwarf was launched in 1843. She was initially constructed as a private yacht for Richard Lloyd. Her design featured an innovative iron hull combined with screw propulsion, which was a cutting-edge technology for the era.- Type: Iron screw steam yacht
- Displacement: 164 tons (builder's measurement)
- Power: Engine of 40 nominal horsepower, driving a single screw propeller.
- Armament: Typically carried one 18-pounder carronade.
Service History
Upon her launch in 1843, Dwarf was promptly purchased by the Royal Navy and commissioned as HMS Dwarf. Her acquisition was a pivotal moment, as it represented the Admiralty's first venture into owning a screw-propelled warship. This preceded the entry into service of HMS Rattler, which was the first purpose-built screw sloop for the Royal Navy, also launched in 1843.Dwarf primarily served as a tender. Initially, she was attached to the gunnery training ship HMS Excellent. Later, she served as a tender to the Commander-in-Chief, Portsmouth, and participated in experimental duties with the Channel Fleet. Her service provided valuable practical experience with the new screw propulsion system, allowing the Royal Navy to evaluate its performance and advantages over traditional paddlewheels and sails. Although her small size and experimental nature limited her role in frontline combat, her operational experience was crucial for the development and widespread adoption of screw propulsion across the fleet.
HMS Dwarf remained in service for a decade before being sold out of the Royal Navy in 1853.
