Screw-driven steamships generally carry the ship prefix "SS" before their names, meaning 'Steam Ship' (or 'Screw Steamer' i.e. 'screw-driven steamship', or 'Screw Schooner' during the 1870s and 1880s, when sail was also carried), paddle steamers usually carry the prefix "PS" and steamships powered by steam turbine may be prefixed "TS" (turbine ship).
A screw steamer or screw steamship (abbreviated "SS") is an old term for a steamship or steamboat powered by a steam engine, using one or more propellers (also known as screws) to propel it through the water. Such a ship was also known as an "iron screw steam ship".
While steam turbine-driven merchant ships such as the Algol-class cargo ships (1972–1973), ALP Pacesetter-class container ships (1973–1974) [37] [38] and very large crude carriers were built until the 1970s, the use of steam for marine propulsion in the commercial market has declined dramatically due to the development of more efficient ...
The scope of the glossary encompasses both the "Old Navy" of the United States (sail or later steam vessels, with ship type named for the rigging or propulsion method [ex. steamer, cutter, schooner]), from its beginnings as the "Continental Navy", through the "New Navy" (revolutionary steam or fueled vessels, with naming derived from a hull ...
steam powered water-jet propulsion James Rumsey (1743 – December 21, 1792) was an American mechanical engineer chiefly known for exhibiting a boat propelled by machinery in 1787 on the Potomac River at Shepherdstown in present-day West Virginia before a crowd of local notables, including Horatio Gates .
The first small vessel that can be considered a steam warship was the Demologos, which was launched in 1815 for the United States Navy. [1] From the early 1820s, the British Navy began building a number of small steam warships including the armed tugs HMS Comet and HMS Monkey, and by the 1830s the navies of America, Russia and France were experimenting with steam-powered warships.

From the first Royal Navy steam vessel in 1820 until 1840, 70 steam vessels entered service, the majority with side-lever engines, using boilers set to 4psi maximum pressure. [8] The low steam pressures dictated the large cylinder sizes for the side-lever engines, though the effective pressure on the piston was the difference between the boiler ...
The vessel's novel features included an iron hull, the use of water ballast, and steam propulsion with a screw propeller. As was still common, an auxiliary sailing rig was also fitted.
