HSwMS Sköld was a small river monitor built for the Swedish Royal Skerry Artillery in the late 1860s.
She was equipped with a dual propulsion system, both hand and steam-driven, although the hand-driven portion was removed early in the ship's career due to complaints from the crew.
This force was to be equipped with ten small monitors to operate in shallow waters that could navigate the Göta Canal system that linked Gothenburg (Swedish: Göteborg) on the west coast to Söderköping on the Baltic Sea.
Her crew initially numbered 40 officers and men, but it was reduced to 29 when the rowing mechanism was removed early in the ship's career.
[2] Sköld's most unusual feature was that John Ericsson designed, and had built in New York City, a combined hand and steam propulsion system.
[1] The ship was briefly armed with a single 267-millimeter (10.5 in) M/66 smoothbore gun, mounted in a long, fixed, oval-shaped turret, before being rearmed in 1870 with a 240-millimeter (9.4 in) M/69 rifled breech loader.
