Hellenic sloop-of-war Kartería (Greek, Modern (1453-);: Καρτερία; Greek for "Perseverance") was the first steam-powered warship to be used in combat operations in history.[1] It was built in 1825 in an English shipyard for the revolutionary Hellenic Navy during the Greek War of Independence, on the order of Capt Frank Abney Hastings, a former Royal Navy officer who had volunteered his services to the Hellenic Navy.
The vessel was built by Daniel Brent Shipwrights in the Greenland South Dockyard, Rotherhithe, London.[2] It was financed mainly from the proceeds of the 2nd Greek Loan raised by the London Philhellenic Committee, but also by Capt Hastings' private funds.
The 233-ton vessel was propelled by steam-powered paddles. Power was generated by 2 small steam engines. The vessel also featured 4 masts and could operate under sail: it was envisaged that the vessel would normally cruise under wind power, but switch to steam-power during combat operations, to allow maximum maneuvrability. It was armed with just 8 guns but all were 68-pounders, the most powerful calibre. The on-board furnaces that burnt coal to generate steam could also be used to heat cannon-shot to a red-hot state, creating highly incendiary missiles.[3]
The ship entered service in Greece in 1826. It was the first steam warship to see combat. (The first steam warship ever built was American, the USS Demologos, a 30-gun armoured warship launched in 1814, but never used in battle).[4]
Under the command of Hastings, the Kartería soon gained a fearsome combat reputation, taking part in numerous operations against the Ottoman Navy. (The Karteria fired 18,000 rounds in 1827 alone). The ship's most celebrated success was a raid on the port of Itea, near Salona (Amfissa) in the Gulf of Corinth, on 29/30 September 1827, where it sank 9 Ottoman ships.[5]
